One of the fundamental principles of green chemistry is to design chemical products that minimize adverse consequences to human health and the environment. While chemists have been designing molecules for 200 years to have a limitless range of commercial applications, little or no attention has been given to developing commercial chemicals while avoiding hazards and toxicity. This book is the first to provide chemists with useful, practical guidance on how to minimize or avoid a wide range of hazards. Building on the insights gained from the pharmaceutical industry over the past 25 years on how to create desirable biological effects, the authors demonstrate how to avoid undesirable biological effects by design.

Organic Chemistry: Structure, Mechanism, Synthesis, Second Edition, provides basic principles of this fascinating and challenging science, which lies at the interface of physical and biological sciences. Offering accessible language and engaging examples and illustrations, this valuable introduction for the in-depth chemistry course engages students and gives future and new scientists a new approach to understanding, rather than merely memorizing the key concepts underpinning this fundamental area. The book builds in a logical way from chemical bonding to resulting molecular structures, to the corresponding physical, chemical and biological properties of those molecules. The book explores how molecular structure determines reaction mechanisms, from the smallest to the largest molecules-which in turn determine strategies for organic synthesis. The book then describes the synthetic principles which extend to every aspect of synthesis, from drug design to the methods cells employ to synthesize the molecules of which they are made. These relationships form a continuous narrative throughout the book, in which principles logically evolve from one to the next, from the simplest to the most complex examples, with abundant connections between the theory and applications. Featuring in-book solutions and instructor PowerPoint slides, this Second Edition offers an updated and improved option for students in the two-semester course and for scientists who require a high quality introduction or refresher in the subject.

Heterogeneous catalytic oxidation is a key technique used in the
large-scale production of organic chemicals. However, the recent
climate of environmental awareness has seen an increase in its use
as a technique for reducing polluting emissions from chemical
factories. Heterogeneous Catalytic Oxidation; Fundamental and
Technological Aspects of the Selective and Total Oxidation of
Organic Compounds presents the essence of catalytic chemistry,
describing the structure of catalysts, the technology in which they
are used and the chemical transformations that occur during the
reaction. Including descriptions of how reactants and products
interact on the molecular scale with the active sites on the
surface of these materials, this text uses catalytic oxidation to
explain the principles of heterogeneous catalysis. Following an
introduction to the principles and chemistry of catalytic
oxidation, Professor Hodnett uses detailed case studies which
represent and illustrate the fundamentals and technology for
specific aspects of heterogeneous catalytic oxidation, including:
This volume summarises recent developments and highlights new techniques which will define possible future directions for small molecule X-ray crystallography. It provides an insight into how specific aspects of crystallography are developing and shows how they may interact or integrate with other areas of science. The development of more sophisticated equipment and the massive rise in computing power has made it possible to solve the three-dimensional structure of an organic molecule within hours if not minutes. This successful trajectory has resulted in the ability to study ever more complex molecules and use smaller and smaller crystals. The structural parameters for over a million organic and organometallic compounds are now archived in the most commonly used database and this wealth of information creates a new set of problems for future generations of scientists. The volume provides some insight into how users of crystallographic structural data banks can navigate their way through a world where "big data" has become the norm. The coupling of crystallography to quantum chemical calculations provides detailed information about electron distributions in crystals affording a much more detailed analysis of bonding than has been possible previously. In quantum crystallography, quantum mechanical wavefunctions are used to extract information about bonding and properties from the measured X-ray structure factors. The advent of quantum crystallography has resulted in form and structure factors derived from quantum mechanics which have been used in advanced refinement and wavefunction fitting. This volume describes how quantum mechanically derived atomic form factors and structure factors are constructed to allow the improved description of the diffraction experiment. It further discusses recent developments in this field and illustrates their applications with a wide range of examples. This volume will be of interest to chemists and crystallographers with an interest in the synthesis, characterisation and physical and catalytic properties of solid-state materials. It will also be relevant for the community of computational chemists who study chemical systems. Postgraduate students entering the field will benefit from a historical introduction to the way in which scientists have used the data derived from crystallography to develop new structural and bonding models.

In recent years, mechanochemistry has become a mainstream technique for chemical synthesis, spanning supramolecular materials, inorganic (main group, coordination complexes, MOFs) and organic synthesis, pharmaceutical screening, materials development, sustainable chemistry and reaction discovery, as well as its more traditional applications in alloying etc. The current time is also exciting in terms of advances in the fundamental understanding of kinetics and some of the first reaction models specific to mechanochemistry are being discovered. Mechanochemistry is far broader than synthesis alone. It is also fundamental to understanding shear processes at the molecular level and is being harnessed to accomplish new chemistry through the controlled mechanical scission of polymers. As such, mechanochemistry brings many disciplines together in an effort to provide greater understanding of fundamental molecular processes for large scale, sustainable manufacturing as well as new science. This Faraday Discussion volume brings together internationally-leading researchers to explore and exchange ideas on the physical and chemical principles underlying mechanochemical phenomena. In this volume the topics covered are organised into the following themes: Advances in synthesis Shear processes and polymer mechanochemistry Kinetics and basic understanding Scale up and industrial implementation

Traditionally, physical organic chemistry and theoretical organic chemistry have been treated as separate disciplines. This new book bridges these two areas in order to give the reader a new perspective on the nature of organic reactivity. A key element of this new approach is the author's extensive nonmathematical description of the recently developed curve-crossing model that describes why chemical reactions have an activation barrier, and specifies the factors that govern the barrier heights. In addition, the author draws from physical chemistry and transition-metal chemistry to present an original and detailed description of electron transfer theory, and covers the recent discovery that the electron transfer process is intimately related to many basic organic processes. This book has been divided into three parts to facilitate its mixture of classical organic chemistry with new and established theoretical ideas. Part A presents an introductory description of molecular orbital and valence bond theories with emphasis on the qualitative aspects that can be applied to practical problems in organic structure and reactivity. Part B describes the key principles of physical organic chemistry and incorporates a mainly qualitative description of the Marcus theory of electron transfer. Building on the theoretical framework developed in parts A and B, part C offers an overview of the basic reactions of organic chemistry: nucleophilic and electrophilic substitution, and radical and pericyclic reactivity. In addition, part C clearly explains the most recent unifying description of organic reactivity for organic chemists and for graduate and advanced undergraduate students. |
