Principles of Asymmetric Synthesis (Paperback, 2nd edition): Robert E. Gawley, Jeffrey Aube Principles of Asymmetric Synthesis (Paperback, 2nd edition)
Robert E. Gawley, Jeffrey Aube
R1,323 Discovery Miles 13 230 Ships in 10 - 15 working days

The world is chiral. Most of the molecules in it are chiral, and asymmetric synthesis is an important means by which enantiopure chiral molecules may be obtained for study and sale. Using examples from the literature of asymmetric synthesis, this book presents a detailed analysis of the factors that govern stereoselectivity in organic reactions.

After an explanation of the basic physical-organic principles governing stereoselective reactions, the authors provide a detailed, annotated glossary of stereochemical terms. A chapter on "Practical Aspects of Asymmetric Synthesis" provides a critical overview of the most common methods for the preparation of enantiomerically pure compounds, techniques for analysis of stereoisomers using chromatographic, spectroscopic, and chiroptical methods.

The authors then present an overview of the most important methods in contemporary asymmetric synthesis organized by reaction type. Thus, there are four chapters on carbon-carbon bond forming reactions, one chapter on reductions, and one on oxidations (carbon-oxygen and carbon-nitrogen bond forming reactions). This organization allows the reader to compare the leading methods for asymmetric synthesis in an appropriate context.

A highlight of the book is the presentation and discussion of transition states at the current level of understanding, for important reaction types. In addition, extensive tables of examples are used to give the reader an appreciation for the scope of each reaction. Finally, leading references are provided to natural product synthesis that has been accomplished using a given reaction as a key step.

The Foundations of Physical Organic Chemistry - Fifty Years of the James Flack Norris Award (Hardcover): E. Thomas Strom, Vera... The Foundations of Physical Organic Chemistry - Fifty Years of the James Flack Norris Award (Hardcover)
E. Thomas Strom, Vera V. Mainz
R5,475 Discovery Miles 54 750 Ships in 10 - 15 working days

This book examines the history and fundamentals of the physical organic chemistry discipline. With the recent flowering of the organic synthesis field, physical organic chemistry has seemed to be shrinking or perhaps is just being absorbed into the toolkit of the synthetic chemist. The only Nobel Prize that can be reasonably attributed to a physical organic chemist is the 1994 award to George Olah, although Jeffrey I. Seeman has recently made a strong case that R. B. Woodward was actually a physical organic chemist in disguise (I). 2014 saw the awarding of the 50th James Flack Norris Award in Physical Organic Chemistry. James Flack Norris was an early physical organic chemist, before the discipline received its name. This book provides insight into the fundamentals of the field, and each chapter is devoted to a major discovery or to noted physical organic chemists, including Paul Schleyer, William Doering, and Glen A. Russell.

A. Wayne Garrison, Jay Gan, Weiping Liu
R2,730 Discovery Miles 27 300 Ships in 10 - 15 working days

Chirality as an environmental phenomenon was dealt with in a thorough and interesting manner in a series of three symposia entitled "Modern Chiral Pesticides: Enantioselectivity and Its Consequences," sponsored by the Agrochemical Division of the American Chemical Society and held in Washington, DC (2005), Boston, MA (2007) and San Francisco, CA (2010). All three symposia included speakers from industry, government and academia, representing several European countries, China, and the United States. Corresponding to this broad group of countries, institutions and speakers, the range of topics touched on almost all facets of chirality as it is manifested in environmental and human exposure and toxicity. The 40 oral and 20 poster presentations indeed approached comprehensive coverage: analysis of enantiomers and other stereoisomers; preparative separation of enantiomers; stereoselective occurrences of chiral pesticides in environment soil and water and in wildlife and human tissues and fluids; stereoselective degradation and metabolism of chiral pesticides; and stereoselective toxicity.
This book is a result of manuscript contributions by some of the oral and poster presenters to the third symposium in 2010. In addition to symposium participants, invitations were extended to the environmental chiral chemistry community in general, including most of the speakers in the 2005 and 2007 symposia, in an attempt to attain good coverage of this rather broad topic. Thus, this ACS Symposium book will generate many new ideas from interested readers and inform them of useful techniques for experimental exploration of the somewhat exotic, but important, area of chiral chemistry of pesticides.

100+ Years of Plastics - Leo Baekeland and Beyond (Hardcover): E. Thomas Strom, Seth Rasmussen 100+ Years of Plastics - Leo Baekeland and Beyond (Hardcover)
E. Thomas Strom, Seth Rasmussen
R5,463 Discovery Miles 54 630 Ships in 10 - 15 working days

This volume consists of written chapters taken from the presentations at the symposium "100+ Years of Plastics: Leo Baekeland and Beyond," held March 22, 2010, at the 239th ACS National Meeting in San Francisco. The symposium celebrates the 100th anniversary of the formation of General Bakelite Corp., which was preceded by Leo Baekland's synthesis of Bakelite in 1907 and the unveiling of the Bakelite process in 1909. It is quite reasonable to use the synthesis of Bakelite as the starting point of the Age of Plastics. Indeed, Time magazine in its June 14, 1999, issue on the 100 most influential people of the 20th century chose Leo Baekeland and his Bakelite synthesis as the sole representative of chemistry.
Leo Baekeland and Bakelite are the topics of the first four chapters of this volume. The first two chapters come from the perspective of Baekeland family members. Carl Kaufmann is related to the Baekeland family through marriage and is the author of the only full-length biography of Baekeland, published as a master's thesis from the University of Delaware. As a family member Kaufmann had access to all of Baekeland's papers. This first chapter (Leo H. Baekeland) is not only a biographical sketch, but an exploration of Baekeland's effect on the chemical industry. Hugh Karraker is Baekeland's great-grandson, and his chapter (A Portrait of Leo H. Baekeland) provides a family picture of the great inventor. Gary Patterson's chapter (Materia Polymerica: Bakelite) goes into the history of Bakelite chemistry, while Burkhard Wagner's contribution (Leo Baekeland's Legacy-100 Years of Plastics) covers the history of Bakelite manufacture through time and space, finishing with a description of another Baekeland legacy, the Baekeland Award given through the North Jersey Section of the ACS.
In later chapters, Les Sperling (History of Interpenetrating Polymer Networks Starting with Bakelite-Based Compositions) covers the improvements in interpenetrating networks. James Economy and Z. Parkar (Historical Perspectives on Phenolic Resins and High-Temperature Aromatic Polyesters of p-Hydroxybenzoic Acid and Their Copolyesters) follow the paths of resoles, novolaks, and related chemicals.

Lipid Oxidation (Hardcover, 2nd edition): E N Frankel Lipid Oxidation (Hardcover, 2nd edition)
E N Frankel
R4,499 Discovery Miles 44 990 Ships in 10 - 15 working days

In this second edition, Edwin Frankel has updated and extended his now well-known book Lipid oxidation which has come to be regarded as the standard work on the subject since the publication of the first edition seven years previously. His main objective is to develop the background necessary for a better understanding of what factors should be considered, and what methods and lipid systems should be employed, to achieve suitable evaluation and control of lipid oxidation in complex foods and biological systems.
The oxidation of unsaturated fatty acids is one of the most fundamental reactions in lipid chemistry. When unsaturated lipids are exposed to air, the complex, volatile oxidation compounds that are formed cause rancidity. This decreases the quality of foods that contain natural lipid components as well as foods in which oils are used as ingredients. Furthermore, products of lipid oxidation have been implicated in many vital biological reactions, and evidence has accumulated to show that free radicals and reactive oxygen species participate in tissue injuries and in degenerative disease.
Although there have been many significant advances in this challenging field, many important problems remain unsolved. This second edition of Lipid oxidation follows the example of the first edition in offering a summary of the many unsolved problems that need further research. The need to understand lipid oxidation is greater than ever with the increased interest in long-chain polyunsaturated fatty acids, the reformulation of oils to avoid hydrogenation and trans fatty acids, and the enormous attention given to natural phenolic antioxidants, including flavonoids and other phytochemicals.

This third volume of NMR Spectroscopy in the Undergraduate Curriculum continues the work we started with the first and second volumes in providing effective approaches for using nuclear magnetic resonance spectrometers as powerful tools for investigating a wide variety of phenomena at the undergraduate level. This volume focuses on upper-level courses and NMR spectroscopy across the curriculum. The applications and strategies in this volume will be helpful to those who are looking to transform their curriculum by integrating more NMR spectroscopy, to those who might not have considered NMR spectroscopy as a tool for solving certain types of problems, or for those seeking funding for a new or replacement NMR spectrometer.

Patrick B. Smith, Richard B. Gross
R5,477 Discovery Miles 54 770 Ships in 10 - 15 working days

This ACS Symposium Series is the product of a symposium held at the 241st National Meeting of the American Chemical Society in Anaheim, CA on March 27-31, 2011. It includes chapters on new biobased building blocks such as the furandicarboxylic acid, polyesters and polyamides from adipic, succinic and sebacic acids with aliphatic diols such as 1,3-propylene glycol, 1,4-butanediol, 1,12-dodecylenediol and isosorbide. The conversion of hydroxymethylfurfural, the dehydration product of hexose sugars, to succinic acid and 1,4-butanediol to produce poly(butylene succinate) is described in one chapter. Also the synthesis of new polymers from plant-derived olefinic monomers such as tulipalin A and studies of composites from cotton by-products are featured in other chapters. There is a strong emphasis on biocatalytic synthesis and polymerization within the book. Chapter topics include the synthesis of ?-hydroxyfatty acids and polymers therefrom, an interesting discussion on the structural differences of the products of the biocatalytic and chemical catalytic synthesis of polyesters from oleic diacid and glycerol and the ability to produce polylactic acid (PLA) and PLA-PHA copolyesters within a "microbial cell factory". Other areas of interest explored in other chapters include recent developments of biobased polymer fibers and oleate-based pressure sensitive adhesives and composites. One chapter describes a large increase in cold-drawn fiber tensile strength by the blending of a small amount of ultrahigh molecular weight (MW) poly(3-hydroxybutyrate) with a much lower MW 3-hydroxybutyrate polymer. The addition of a rubber and inorganic fillers to normally brittle PLA was found to dramatically improve its ductility. Finally, there are several chapters on seed oil-based polyurethanes, one on fibers from soy proteins and composites from starch.

Additives for Plastics Handbook (Hardcover, 2nd edition): J Murphy Additives for Plastics Handbook (Hardcover, 2nd edition)
J Murphy
R6,305 Discovery Miles 63 050 Ships in 10 - 15 working days

Both technically and economically, additives form a large and increasingly significant part of the polymer industry, both plastics and elastomers. Since the first edition of this book was published, there have been wide-ranging developments, covering chemistry and formulation of new and more efficient additive systems and the safer use of additives, both by processors in the factory and, in the wider field, as they affect the general public.

This new edition follows the successful formula of its predecessor, it provides a comprehensive view of all types of additives, concentrating mainly on their technical aspects (chemistry/formulation, structure, function, main applications) with notes on the commercial background of each. The field has been expanded to include any substance that is added to a polymer to improve its use, so including reinforcing materials (such as glass fibre), carbon black and titanium dioxide.

This is a book which has been planned for ease of use and the information is presented in a way which is appropriate to the users' needs.

Chemical Dynamics in Condensed Phases - Relaxation, Transfer and Reactions in Condensed Molecular Systems (Hardcover): Abraham... Chemical Dynamics in Condensed Phases - Relaxation, Transfer and Reactions in Condensed Molecular Systems (Hardcover)
Abraham Nitzan
R4,805 Discovery Miles 48 050 Ships in 10 - 15 working days

This text provides a uniform and consistent approach to diversified problems encountered in the study of dynamical processes in condensed phase molecular systems. Given the broad interdisciplinary aspect of this subject, the book focuses on three themes: coverage of needed background material, in-depth introduction of methodologies, and analysis of several key applications. The uniform approach and common language used in all discussions help to develop general understanding and insight on condensed phases chemical dynamics. The applications discussed are among the most fundamental processes that underlie physical, chemical and biological phenomena in complex systems.
The first part of the book starts with a general review of basic mathematical and physical methods (Chapter 1) and a few introductory chapters on quantum dynamics (Chapter 2), interaction of radiation and matter (Chapter 3) and basic properties of solids (chapter 4) and liquids (Chapter 5). In the second part the text embarks on a broad coverage of the main methodological approaches. The central role of classical and quantum time correlation functions is emphasized in Chapter 6. The presentation of dynamical phenomena in complex systems as stochastic processes is discussed in Chapters 7 and 8. The basic theory of quantum relaxation phenomena is developed in Chapter 9, and carried on in Chapter 10 which introduces the density operator, its quantum evolution in Liouville space, and the concept of reduced equation of motions. The methodological part concludes with a discussion of linear response theory in Chapter 11, and of the spin-boson model in chapter 12. The third part of the book applies the methodologies introducedearlier to several fundamental processes that underlie much of the dynamical behaviour of condensed phase molecular systems. Vibrational relaxation and vibrational energy transfer (Chapter 13), Barrier crossing and diffusion controlled reactions (Chapter 14), solvation dynamics (Chapter 15), electron transfer in bulk solvents (Chapter 16) and at electrodes/electrolyte and metal/molecule/metal junctions (Chapter 17), and several processes pertaining to molecular spectroscopy in condensed phases (Chapter 18) are the main subjects discussed in this part.

R4,022 Discovery Miles 40 220 Ships in 10 - 15 working days

A major strength of American Chemical Society (ACS) is the large number of volunteers who help to grow and sustain the organization, from local sections to technical divisions, from regional to national meetings, from task forces to national committees, and from conducting research to writing and reviewing manuscripts for journals. Some of them spend literally thousands of hours on behalf of ACS and the global chemistry enterprise, helping students or fellow scientists, organizing meetings and symposia, and reaching out to the local communities. One of the people who excelled in these efforts was the late Prof. Ernest L. Eliel. For many years he taught at the University of Notre Dame and the University of North Carolina and was an acknowledged leader in organic stereochemistry and conformational analysis. He was also a leader at ACS, serving as ACS President in 1992 and Chair of ACS Board of Directors in 1987-89. Unfortunately Prof. Eliel died in 2008, but the ACS held a symposium in 2016 honoring his work. This book features two volumes highlighting stereochemistry and global connectivity, which represent two of the key legacies of Prof. Eliel. Because stereochemistry is a fundamental chemistry concept, ongoing research is carried out in different subfields of chemistry (such as organic, medicinal, carbohydrates, polymers), using various analytical techniques (such as NMR, X-ray crystallography, and circular dichroism). The two volumes of this book contain many research papers that represent cutting-edge research in all the above areas. Because chemistry is now a world-wide enterprise, global connectivity is important to chemistry practitioners, and the chapters on international activities should be of great interest as well.

Investigating Classroom Myths through Research on Teaching and Learning (Hardcover): Diane Bunce Investigating Classroom Myths through Research on Teaching and Learning (Hardcover)
Diane Bunce
R5,466 Discovery Miles 54 660 Ships in 10 - 15 working days

This book is meant to be a companion volume for the ACS Symposium Series Book entitled Nuts and Bolts of Chemical Education Research. In the Nuts and Bolts book (edited by Diane M. Bunce and Renee Cole), readers were presented with information on how to conduct quality chemical education research. In the Myth book, exemplars of chemical education research are featured. In the cases where the chapter in the book is describing research that has already been published (typically in the Journal of Chemical Education), additional information is provided either in terms of research questions investigated that were not reported in the published article or background information on decisions made in the research that helped the investigation. The main focus of this type of discussion is to engage the reader in the reality of doing chemical education research including a discussion of the authors' motivation. It is expected that these two books could be used as textbooks for graduate chemical education courses showing how to do chemical education research and then providing examples of quality research.

Structural crystallographic studies can determine not only the full stereochemistry of chemical species but also their details of arrangement in the crystal. Such geometrical data provide an essential basis for the interpretation of chemical, physical, and biological properties of chemical species. This volume contains key papers presented at the seventh symposium on organic crystal chemistry at Poznan in Poland. Among the themes discussed were factors influencing molecular conformation and polymorphism, chemical and biological activity, intermolecular interactions, crystal chemistry of polymers and molecular modelling.

Acids and Bases - Solvent Effects on Acid-Base Strength (Hardcover): Brian G. Cox Acids and Bases - Solvent Effects on Acid-Base Strength (Hardcover)
Brian G. Cox
R3,095 Discovery Miles 30 950 Ships in 10 - 15 working days

Acids and bases are ubiquitous in chemistry. Our understanding of them, however, is dominated by their behaviour in water. Transfer to non-aqueous solvents leads to profound changes in acid-base strengths and to the rates and equilibria of many processes: for example, synthetic reactions involving acids, bases and nucleophiles; isolation of pharmaceutical actives through salt formation; formation of zwitter- ions in amino acids; and chromatographic separation of substrates. This book seeks to enhance our understanding of acids and bases by reviewing and analysing their behaviour in non-aqueous solvents. The behaviour is related where possible to that in water, but correlations and contrasts between solvents are also presented. Fundamental background material is provided in the initial chapters: quantitative aspects of acid-base equilibria, including definitions and relationships between solution pH and species distribution; the influence of molecular structure on acid strengths; and acidity in aqueous solution. Solvent properties are reviewed, along with the magnitude of the interaction energies of solvent molecules with (especially) ions; the ability of solvents to participate in hydrogen bonding and to accept or donate electron pairs is seen to be crucial. Experimental methods for determining dissociation constants are described in detail. In the remaining chapters, dissociation constants of a wide range of acids in three distinct classes of solvents are discussed: protic solvents, such as alcohols, which are strong hydrogen-bond donors; basic, polar aprotic solvents, such as dimethylformamide; and low-basicity and low polarity solvents, such as acetonitrile and tetrahydrofuran. Dissociation constants of individual acids vary over more than 20 orders of magnitude among the solvents, and there is a strong differentiation between the response of neutral and charged acids to solvent change. Ion-pairing and hydrogen-bonding equilibria, such as between phenol and phenoxide ions, play an increasingly important role as the solvent polarity decreases, and their influence on acid-base equilibria and salt formation is described.

Since their discovery, disinfection by-products (DBPs) have become one of the major driving forces in drinking water regulations, research and water utility operations throughout the world. The list of DBPs that can occur in treated drinking waters has grown from a few trihalomethanes to a long list of halogenated and non-halogenated organic or inorganic compounds. This list is expected to continue to grow as the analytical techniques are improved, as more information on their toxicity is developed, and as more occurrence studies are conducted. This book documents the latest DBP research findings, including emerging issues and state-of-the-art studies. Specifically, papers on the occurrence, formation, control, and health effects of emerging (unregulated) halogenated (e.g., brominated) and nonhalogenated (e.g., nitrosamines) DBPs (e.g., emerging nitrogenous vs. regulated carbonaceous DBPs) are presented. In addition to the characterization and reactivity of natural organic matter to form DBPs, new studies on algal organic matter and treated wastewater as sources of DBPs and their precursors are discussed.

Kirt A. Page, Christopher L. Soles, James Runt
R5,481 Discovery Miles 54 810 Ships in 10 - 15 working days

Polymeric materials have been and continue to be a focus of research in the development of materials for energy conversion, storage and delivery applications (fuel cells, batteries, photovoltaics, capacitors, etc.). Significant growth in this field started in the early 1990s and has continued to grow quite substantially since that time. Polymeric materials now have a prominent place in energy research.
For polymers, particularly polyelectrolytes, being used in fuel cell and battery applications, the importance of chain microstructure, chain dynamics, and nanoscale morphology on the overall performance characteristics of these materials cannot be overstated. As further advancements are made in polymer chemistry, control of nanostructure and characterization, there is a necessity for organized forums that foster cross-fertilization of knowledge and ideas between experts in polymer chemistry, chemical engineering, and polymer physics. This volume is the result of such a forum.
Most of the chapters in this book are based on a cross-section of the oral presentations in a symposium on Polymers for Energy Storage and Delivery held in March of 2011 as part of the 241st ACS National Meeting & Exposition (Anaheim, CA). The book contains 17 chapters presented in two parts. Part one focuses on polymers for battery applications and will cover theory and modeling, novel materials, and materials characterization. Professor Janna Maranas has provided an excellent review of the current state of understanding in polyelectrolytes as ion conductors in batteries. Part two will focus on polymers for fuel cells and will cover novel materials, transport, and materials characterization with a brief introduction into the history of polyelectrolytes for fuel cells and the classes of materials being pursued. Realizing the common role that nanostructure plays in both battery and fuel cell applications, Professor Moon Jeong Park and coworkers have also contributed a chapter demonstrating the role of nanostructured polyelectrolyte systems in energy storage and delivery. In addition, the editors are pleased to have a chapter-contributed by Professor Howard Wang and staff scientists of the NIST Center for Neutron Research-on the most state-of-art, in-situ neutron methods for studying lithium ion batteries.

This symposium book covers novel and exciting approaches in biomedical spectroscopy. Several chapters deal with infrared and Raman spectroscopy. These complimentary vibrational spectroscopic techniques are capable of monitoring molecular structures as well as structural changes. Such studies are of interest for understanding diseases at a molecular level as well as for developing techniques for efficient early diagnosis based on molecular structural information. The chapters demonstrate also applications vibrational spectroscopy in proteomics and the characterization of micro organisms. The second section of the book introduces surface enhanced Raman scattering (SERS), demonstrates the application of the effect in the biomedical field and develops the concept of multifunctional nanosensors. The measurement of intrinsic optical signals from biological objects such as nerve tissue are discussed in the next section of the book. Chapters deal also with Coherent anti-Stokes Raman scattering (CARS) and fluorescence fluctuation spectroscopy. Other chapters illustrate how photons of very different energies, in the Terahertz and in the ultra violet range, can be used to retrieve molecular structural information from native biomolecules. The electrical properties of protein molecules adsorbed onto a gold substrate are studied by using a scanning Kelvin nanoprobe in a microarray format. The final chapters in the book demonstrate the powerful combination of different spectroscopic techniques for the characterization of biomolecules as well as native and engineered biomaterials. These chapters combine information from Raman and Inelastic Neutron Scattering, optical absorbance and energy dispersive X-ray analysis, positron annihilation lifetime spectroscopy (PALS), 1H NMR, and 129Xe NMR X-ray diffraction and fluorescence resonance energy transfer.
