Explores the potential of new types of anion-binding catalysts to solve challenging synthetic problems Anion-Binding Catalysis introduces readers to the use of anion-binding processes in catalytic chemical activation, exploring how this approach can contribute to the future design of novel synthetic transformations. Featuring contributions by world-renowned scientists in the field, this authoritative volume describes the structure, properties, and catalytic applications of anions as well as synthetic applications and practical analytical methods. In-depth chapters are organized by type of catalyst rather than reaction type, providing readers with an accessible overview of the existing classes of effective catalysts. The authors discuss the use of halogens as counteranions, the combination of (thio)urea and squaramide-based anion-binding with other types of organocatalysis, anion-binding catalysis by pnictogen and tetrel bonding, nucleophilic co-catalysis, anion-binding catalysis by pnictogen and tetrel bonding, and more. Helping readers appreciate and evaluate the potential of anion-binding catalysis, this timely book: Illustrates the historical development, activation mode, and importance of anion-binding in chemical catalysis Explains the analytic methods used to determine the anion-binding affinity of the catalysts Describes catalytic and synthetic applications of common NH- and OH-based hydrogen-donor catalysts as well as C-H triazole/triazolium catalysts Covers amino-catalysis involving enamine, dienamine, or iminium activation approaches Discusses new trends in the field of anion-binding catalysis, such as the combination of anion-binding with other types of catalysis Presenting the current state of the field as well as the synthetic potential of anion-binding catalysis in future, Anion-Binding Catalysis is essential reading for researchers in both academia and industry involved in organic synthesis, homogeneous catalysis, and pharmaceutical chemistry.

Most standard texts in basic organic chemistry require the student to memorize dozens of organic reactions. This is certainly necessary to master the discipline. Unfortunately, most texts do not emphasize why these reactions occur and, just as important, why other reactions that might seem conceivable to the student do not occur. Without this understanding, students tend to forget what they have memorized soon after the course is over. It is the purpose of this book to familiarize the student with the principles governing organic reactivity and to provide a "feel" for organic chemistry that is impossible to secure by memory alone. Digesting the ideas in this book will, we hope, not only explain the common organic reactions but also allow the student to predict the prod ucts and by-products of reactions he has never seen before. Indeed, the creative student might even become capable of designing new reactions as might be required in a complex organic synthesis. In Chapter 1, we cover the basic principles including bonding, nuclear charge, resonance effects, oxidation-reduction, etc. It is a brief discussion, but it nonetheless provides the basis for understanding reaction mechanisms th~t will be treated later on. We highly recommend that this material be reviewed and that the v VI PREFACE problems be worked at the end of the chapter. Answers are given to all problems. In Chapter 2, reaction mechanisms are presented in an increas ing order of difficulty.

Heterocycles are ubiquitously present in nature and occupy a unique place in organic chemistry as they are part of the DNA and haemoglobin that make life possible. The Chemistry of Heterocycles covers an introduction to the topic, followed by a chapter on the nomenclature of all classes of isolated, fused and polycyclic heterocycles. The third chapter delineates the highly strained three membered N,O and S containing aromatic and non-aromatic heterocycles with one and more than one similar and dissimilar heteroatom. The four-membered heterocycles are abundantly present in various natural and synthetic products of pharmacological importance. This chapter describes the natural abundance, synthesis, chemical reactivity, structural features and their medicinal importance. This class of compounds are present as sub-structures in penicillin and cytotoxic Taxol. Lastly, a chapter on the natural abundance, synthesis, chemical reactivity and pharmacological importance of 5-membered heterocycles with N,O,S heteroatom is covered. The chemistry of heterocycles with mixed heteroatom such as, N-S, N-O, N-S etc. is also described. - Gives in-depth, clear information about various systems of nomenclature along with widely acceptable IUPAC system for naming various classes of heterocycles - Provides complete information about natural occurrences, synthesis, chemical reactivity, pharmacological importance of heterocycles and their application in material science - Highly relevant for graduate students and researchers, providing updated information about various isolated and fused N,O and,S containing heterocycles

"I have no dress except the one I wear every day. If you are going to be kind enough to give me one, please let it be practical and dark so that I can put it on afterwards to go to the laboratory", said Marie Curie about her wedding dress. According to her lecture notes, Gertrude B. Elion is quoted a few decades later: "Don't be afraid of hard work. Don't let others discourage you, or tell you that you can't do it. In my day I was told women didn't go into chemistry. I saw no reason why we couldn't." These two quotations from famous, Nobel Prize winning chemists amply demonstrate the challenges that female scientists in the past centuries have had to overcome; challenges that are still sometimes faced by the current generation. They "must have the noblest courage, quite extraordinary talents and superior genius" wrote Carl Friedrich Gauss 1807 in a letter to mathematician Sophie Germain. For the official book to celebrate the International Year of Chemistry, the European Association for Chemical and Molecular Sciences (EuCheMS) has chosen one of the central goals of the International Year: the contribution and role of women in chemistry. This celebration, which is the focus of European Women in Chemistry, takes us on a journey through centuries of chemical research, focusing on the lives of those amazing women from ancient times to the current day who dared to study this subject, often against advice or societal expectations. These portraits emphasize the extraordinary path and personality of these fascinating women, their major contribution to chemistry, but all in the context of their time and social environment. Some of these women, like Marie Curie and Dorothy Crowfoot Hodgkin, are famous and still well-known today. Others have contributed significantly to the development of science and lived an exceptional life, but are nowadays almost forgotten. This book is a tribute to all of them and a motivation for new generations to come to tread new paths, fight for unusual ideas and control one?s own destiny.

This book presents an authoritative review of the most significant findings about all the epigenetic targets (writers, readers, and erasers) and their implication in physiology and pathology. The book also covers the design, synthesis and biological validation of epigenetic chemical modulators, which can be useful as novel chemotherapeutic agents. Particular attention is given to the chemical mechanisms of action of these molecules and to the drug discovery prose which allows their identification. This book will appeal to students who want to know the extensive progresses made by epigenetics (targets and modulators) in the last years from the beginning, and to specialized scientists who need an instrument to quickly search and check historical and/or updated notices about epigenetics.

The subject of the book is electron transfer reactions in organic chemistry, with the emphasis on mechanistic aspects. The theoretical framework is that of the Marcus theory, well-known from its extensive use in inorganic chemistry. The book deals with definitions of electron transfer, theory of electron transfer reactions (Marcus' and Pross-Shaik's approach) experimental diagnosis of electron transfer reactions, examples from inorganic/organic reactants and purely organic reactants, electro- and photochemical electron transfer, electron transfer catalyzed reactions, connections between electron transfer and polar mechanisms, and applications of electron transfer, such as electrosynthesis of organic chemicals, photochemical energy storage, conducting organic materials and chemiluminescence. The approach is new in so far as no comparable book has been published. The book will be of value to anyone interested in keeping track of developments in physical organic chemistry.
