This book summarizes the preparation, characterization and applications of rubber based nano blends. Rubbers from natural and synthetic polymers and their blends are discussed in the individual chapters, including nitrile, polyurethane, chlorosulphonated, polybutadiene, styrene butadiene, polychloroprene rubbers. In each chapter, contributors from academia and industry describe the preparation and characterization of the rubber blends. Therefore, a variety of characterization methods like tensile testing, differential scanning calorimetry, dynamical mechanical analysis, thermogravimetric analysis, electron microscopy, scattering and diffraction techniques, and rheology measurements are utilized. The authors evaluate the properties of the different materials and discuss numerous fields of application, ranging from biomedicine, packaging, coatings and automobile to aerospace.

The preceding volume appeared in 1987 and covered the literature up to the end of 1984. The present work extends the coverage to the end of 1994 with a sprinkling of references to 1995 papers. Nearly 900 new qui nones are described, including one or two which were overlooked previously, together with new work on older compounds. For each new quinone information is provided on the distribution, spectra, structure and chemistry, and on biosynthesis where available. Sadly, there is very little new chemistry, as structures are now elucidated almost entirely by spectroscopic methods and X-ray analysis. As always I am grateful to many colleagues who sent me papers and other information in advance of publication. 1972 and 1987 volumes are referred to as NOQ II and NOQ III, The respectively. In the spectroscopic data the notation (?) indicates that informa tion is missing or is dubious. R.H.T. Aberdeen, November 1995 1 Benzoquinones 1 New sources of p-benzoquinone are the cephalic glands of Eucera bees and 2 Arthrobacter bacteria and it is part ofthe defensive secretion ofthe caterpillar 3 Romalea guttata. However, the natural occurrence of o-benzoquinone has not been reported and is unlikely. Simple monosubstituted o-benzoquinones occur 4 only as transient metabolic intermediates. It has been shown that in the leaves of X anthium occidentale (Compositae) chlorogenic acid is in equilibrium with a small amount of the corresponding o-quinone but the latter has not been isolated."
In this dissertation, Marie-Helene Larraufie develops original radical and pallado-catalyzed methodologies to enable the synthesis of several classes of bioactive nitrogen-containing heterocycles. New radical cascades employing the N-acylcyanamide moiety offer straightforward routes to quinazolinones and guanidines, as well as new insights into the mechanism of homolytic aromatic substitutions. In parallel, Larraufie expands the scope of visible light photoredox catalysis to the ring opening of epoxides and aziridines, thus providing new sustainable alternatives for the generation of radicals. Furthermore, in a collaborative effort with the Catellani group, the author investigates dual palladium/norbornene catalysis. First, she develops a C-amination coupling variant of the Catellani reaction with unprotected amines which provides an expeditious route to phenanthridines. Then, she examines the influence of the chelating effect on Pd(IV) intermediates reactivity with the help of experimental studies and DFT calculations. The work in this thesis has resulted in numerous publications in high impact journals.The clarity and depth of the experimental section will be useful for students and researchers working in this field.
Considering the high level of our knowledge concerning covalent bond formation in the organic chemistry of molecules, our understanding of the principles involved in organic solid design is almost in its infancy. While chemists today are able to synthesize organic molecules of very high complexity using sophisticated methods of preparation, they lack general approaches enabling them to reliably predict organic crystalline or solid structures from molecular descriptors - no matter how simple they are. On the other hand, nearly all the organic matter surrounding us is not in the single-molecule state but aggregated and condensed to form liquid or solid molecular assemblages and structural arrays giving rise to the appearances and properties of organic compounds we usually observe. Obviously, the electrical, optical or magnetic properties of solid organic materials that are important requirements for future technologies and high-tech applications, as well as the stability and solubility behavior of a medicament depend on the structure of the molecule and the intramolecular forces, but even more decisively on the intermolecular forces, i. e. the packing structure of the molecules to which a general approach is lacking. This situation concerned ]. Maddox some years ago to such a degree that he described it as "one of the continuing scandals in the physical sciences" [see (1998) Nature 335:201; see also Ball, P. (1996) Nature 381:648]. The problem of predicting organic solid and crystal structures is very dif- cult.
The first contribution describes apolar and polar molecular fossils and, in particular biomarkers, along the lines usually followed in organic chemistry textbooks, and points to their bioprecursors when available. Thus, the apolar compounds are divided in linear and branched alkanes followed by alicyclic compounds and aromatic and heterocyclic molecules, and, in particular, the geoporphyrins. The polar molecular fossils contain as functional groups or constituent units ethers, alcohols, phenols, carbonyl groups, flavonoids, quinones, and acids, or are polymers like kerogen, amber, melanin, proteins, or nucleic acids. The final sections discuss the methodology used and the fundamental processes encountered by the biomolecules described, including diagenesis, catagenesis, and metagenesis. The second contribution covers the distribution of phthalides in nature and the findings in the structural diversity, chemical reactivity, biotransformations, syntheses, and bioactivity of natural and semisynthetic phthalides.
An important aspect of molecular engineering is the property directed' synthesis of large molecules and molecular assemblies. Synthetic expertise has advanced to a state which allows the assembly of supramolecules containing thousands of atoms using a construction kit' of molecular building blocks. Expansion in the field is driven by the appearance of new building blocks and by an improved understanding of the rules for joining them in the design of nanometer-sized devices. Another aspect is the transition from supramolecules to materials. At present no single molecule (however large) has been demonstrated to function as a device, but this appears to be only a matter of time. In all of this research, which has a strongly multidisciplinary character, both existing and yet to be developed analytical techniques are and will remain indispensable. All this and more is discussed in Molecular Engineering for Advanced Materials, which provides a masterly and up to date summary of one of the most challenging research fields to emerge in recent time.
In recent years silicon-centered radicals have played an important role in organic synthesis, polymer chemistry and material sciences. The aim of this book is to offer for the first time a description of silyl radicals within an interdisciplinary context, connecting structural characteristics and chemical properties to their application in different areas of chemistry.This is the first time different aspects of silyl radicals have been brought together. This book is an excellent reference tool for experienced practitioners of radical and/or silicon chemistry. It presents various aspects of these intermediates in an original, comprehensive fashion. This book is essential for anyone working in free radical and/or silicon chemistry as well as for those who want to approach these fields for the first time.
The ASI workshop on "Selectivities in Lewis Acid Promoted Reactions" held in the Emmantina-Hotel in Athens-Glyfada, Greece, October 2-7, 1988 was held to bring some light into the darkness of Lewis acid induced processes. As such the workshop reflects some current trends in organic synthesis, where Lewis acids are becoming a powerful tool in many different modern reactions, e.g. Diels-Alder reactions, Ene reactions, Sakurai reactions, and in general silicon and tin chemistry. The objective of this meeting was to bring together most of the world experts in the field to discuss the major reactions promoted by Lewis acids. Organic synthesis will play a major role in this book connected with some fundamental mechanistic work on allylsilane and -tin chemistry. Both natural product synthesis and unnatural molecules are presented in the chapters. The book presents all the 15 invited lectures and the contributions of 15 posters. I am confident that the material presented in this book will stimulate the chemistry, which has been discussed on our meeting, around the world. The meeting and the book were only possible through a grant of the NATO Scientific Affairs Devision and financial support by the following companies: Kali Chemie (Hannover, W-Germany), E. Merck (Darmstadt, W-Germany), Sandoz (Basel, Switzerland), Schering (Berlin, W-Germany).

Since 1988, there has been much literature published on the
chemistry of nitric oxide, particularly in the field of
S-nitrosation and the chemistry of S-nitroso compounds. Written by
a chemist for the chemistry community, this book provides an update
of the chemistry of nitrosation reactions, dealing with both the
synthetic and mechanistic aspects of these reactions. It also looks
at the chemistry of nitric oxide in relation to the amazing
biological properties of this simple diatomic molecule, which were
unknown until around 1990.
This revised, new edition retains its class-tested coverage of how metals behave in water while updating and expanding information about metals processing methods. The book further retains its emphasis on predicting and engineering the way metals are extracted from ore sources, separated from unwanted entities, recovered as metals, and purified using water based processing. The transformation of minerals to metals requires hydrometallurgical processing for nearly all of the nonferrous metals we use. This book elucidates the associated fundamentals and processing applications as well as related tools to assess processes and performance. The new edition further includes additional photographs, updated drawings, supplementary data, updated descriptive information, and new detail on rare earth elements processing as well as recycling and byproduct recovery of metals.
This thesis discusses the use of asymmetric organic catalysis for the direct enantioselective synthesis of complex chiral molecules, and by addressing the many aspects of both vinylogy and atropisomerism, it appeals to researchers and scholars interested in both areas. Organocatalysis is a relatively modern and "hot" topic in the chemical community; it is constantly expanding and its use has been extended to interesting areas like vinylogous reactivity and atropisomerism. Vinylogous systems are very important for their synthetic applications but also pose a number of challenges, the most notable of which are their reduced reactivity and the reduced stereocontrol at these positions. On the other hand, atropisomeric systems are even more important because of the huge potential they have as drugs, ligands and catalysts. Chemists have only recently "recognized" the importance of these two areas and are focusing their efforts on studying them and the challenges they pose. This thesis offers an extensive introduction on the general aspects of chirality and organocatalysis and an equally extensive experimental section that allow nonexperts to understand the discussion section and reproduce the experiments.
As the second volume in a comprehensive encyclopedia of organic reactions, this work provides an elaborated description of the experimental methods used for the oxidation of alcohols to acids. It supplies important data on possible interferences from protecting groups and functional groups, as well as on potential side-reactions. This book is a must for anyone involved in the preparation of organic compounds.
Thermodynamic data form the basis for separation processes used in different fields of science and industry, from specialty chemicals to foods and pharmaceuticals. One obstacle to developing new production processes, products, or optimization is the lack, or inaccessibility, of experimental data related to phase equilibrium. "Access More Than 1200 Data Sets, Including 810 Binary Systems, 325 Ternary Systems, and 25 Quaternary (or Higher) Systems" The CRC Handbook of Liquid-Liquid Equilibrium Data of Polymer Solutions provides a thorough and up-to-date compilation of experimental liquid-liquid equilibrium (LLE) data and their original sources. Arranged in a consistent format, the handbook provides convenient access to cloud-point and coexistence data as well as upper and lower critical solution temperatures and important demixing data for each system. "An Excellent Companion to the Author's Previous Collections of Thermodynamic Data!" While the author's previous data compilations center around specific types of polymer systems, Wohlfharth'slatest work distinguishes itself by focusing instead on representing LLE data for all types of polymer systems in a single source.
Few polymer chemists have much familiarity with recent developments in the synthesis of speciality polymers. This volume provides up-to-date reviews of areas of current interest and is directed at polymer chemists in the academic world and industry.
The Chemistry of Heterocyclic Compounds, since its inception, has been recognized as a cornerstone of heterocyclic chemistry. Each volume attempts to discuss all aspects - properties, synthesis, reactions, physiological and industrial significance - of a specific ring system. To keep the series up-to-date, supplementary volumes covering the recent literature on each individual ring system have been published. Many ring systems (such as pyridines and oxazoles) are treated in distinct books, each consisting of separate volumes or parts dealing with different individual topics. With all authors are recognized authorities, the Chemistry of Heterocyclic Chemistry is considered worldwide as the indispensable resource for organic, bioorganic, and medicinal chemists.
Since the publication of our earlier book on transition metal mediated organic synthesis, * there has been a widespread increase of interest in this topic, and transition metal based methodology has become firmly established in many areas of organic chemistry. The direct, catalytic formation of organic carbonyl compounds using carbon monoxide as the source of the carbonyl group has seen exceptional progress, and this carbonylation chemistry is being used increasingly in research and on a larger scale for fine chemicals production. In view of these developments, there is a need for a modem, practi cally oriented book dealing with transition metal based carbonylation chemistry. The present monograph should help fulfill this need, since it is intended specifically to foster the adoption of catalytic carbonylation as a general tool in synthetic organic chemistry. It deals exclusively with reactions involving the interconversion of carbon monoxide and organic carbonyl compounds, and although the majority of the reactions discussed involve catalytic formation of carbonyl compounds, potentially valuable syntheses requiring stoichiometric quantities of transition metal are also included. In addition, a chapter is devoted to the remarkably useful reverse transformation (decarbonylation), in which an organic carbonyl group is eliminated in the form of carbon monoxide."
