Neutral reactive intermediates -- radicals, carbenes, nitrenes, and aryenes -- occupy a fascinating place in the history of organic chemistry. First regarded as mere curiosities, neutral reactive intermediates ultimately came under the intense scrutiny of physical organic chemists from a mechanistic point-of-view. This concise text concentrates on how these electron-deficient species now play a key role in synthetic chemistry research. Important reactions are clearly and simply laid out with carefully chosen examples that illustrate their use in organic synthesis. Each chapter includes problems as well as suggestions for further reading. Undergraduates will find Reactive Intermediates an invaluable summary of this important topic in organic chemistry--one that fills a gap created by the superficial treatment accorded these valuable compounds in most chemistry textbooks.

Most reactions in organic chemistry do not proceed in a single step but rather take several steps to yield the desired product. In the course of these multi-step reaction sequences, short-lived intermediates can be generated that quickly convert into other intermediates, reactants, products or side products. As these intermediates are highly reactive, they cannot usually be isolated, but their existence and structure can be proved by theoretical and experimental methods. Using the information obtained, researchers can better understand the underlying reaction mechanism of a certain organic transformation and thus develop novel strategies for efficient organic synthesis. The chapters are clearly structured and are arranged according to the type of intermediate, providing information on the formation, characterization, stereochemistry, stability, and reactivity of the intermediates. Additionally, representative examples and a problem section with different levels of difficulty are included for self-testing the newly acquired knowledge. By providing a deeper understanding of the underlying concepts, this is a musthave reference for PhD and Master Students in organic chemistry, as well as a valuable source of information for chemists in academia and industry working in the field. It is also ideal as primary or supplementary reading for courses on organic chemistry, physical organic chemistry or analytical chemistry.

Theoretical Aspects of Chemical Reactivity provides a broad overview of recent theoretical and computational advancements in the field of chemical reactivity. Contributions have been made by a number of leaders in the field covering theoretical developments to applications in molecular systems and clusters. With an increase in the use of reactivity descriptors, and fundamental theoretical aspects becoming more challenging, this volume serves as an interesting overview where traditional concepts are revisited and explored from new viewpoints, and new varieties of reactivity descriptors are proposed. Includes applications in the frontiers of reactivity principles, and introduces dynamic and statistical viewpoints to chemical reactivity and challenging traditional concepts such as aromaticity. * Written by specialists in the field of chemical reactivity * An authoritative overview of the research and progress * An essential reference material for students

Many controversial issues revolve around complex scientific arguments which can be better understood with at least a minimal knowledge and understanding of the chemical reactions and processes going on in the world around us. This textbook offers an accessible introduction to chemical principles and concepts, and applies them to relevant environmental situations and issues. Written for students who have not taken A' level chemistry, this book bridges the gap between GSCE chemistry and first year undergraduate level.

A range of alternative mechanisms can usually be postulated for most organic chemical reactions, and identification of the most likely requires detailed investigation. Investigation of Organic Reactions and their Mechanisms will serve as a guide for the trained chemist who needs to characterise an organic chemical reaction and investigate its mechanism, but who is not an expert in physical organic chemistry. Such an investigation will lead to an understanding of which bonds are broken, which are made, and the order in which these processes happen. This information and knowledge of the associated kinetic and thermodynamic parameters are central to the development of safe, efficient, and profitable industrial chemical processes, and to extending the synthetic utility of new chemical reactions in chemical and pharmaceutical manufacturing, and academic environments. Written as a coherent account of the principal methods currently used in mechanistic investigations, at a level accessible to academic researchers and graduate chemists in industry, the book is highly practical in approach. The contributing authors, an international group of expert practitioners of the techniques covered, illustrate their contributions by examples from their own research and from the relevant wider chemical literature. The book covers basic aspects such as product analysis, kinetics, catalysis, and investigation of reactive intermediates. It also includes material on significant recent developments, e.g. computational chemistry, calorimetry, and electrochemistry, in addition to topics of high current industrial relevance, e.g. reactions in multiphase systems, and synthetically useful reactions involving free radicals and catalysis by organometallic compounds.

Currently there is no concise teaching text aimed at 2/3rd year undergraduates on organosulfur chemsitry. Organosulfur chemistry is widely taught at this level. After a brief introductory chapter the main part of the book deals with the preparation and chemical properties of the principal types of organosulfur compounds classified under the headings: Divalent sulfur compounds, Tricoordinate sulfur compounds, and Tetracoordinate sulfur compounds. In choosing examples to illustrate the text, the guiding principle has been that the illustrations should provide insight into and an understanding of the characteristic features of organosulfur chemistry. Two concluding chapters deal, on the one hand, with applications of organosulfur compounds in organic synthesis and, on the other, with a brief summary of organoselenium chemistry, highlighting the similarities and differences with respect to organosulfur chemistry.

Key texts in the renowned Oxford Chemistry Primers series have been fully refreshed and updated to suit the needs of today's students, lecturers, and postgraduate researchers. The rigorous and yet accessible treatment of each subject area is ideal for those wanting to know more about a particular topic not covered comprehensively in existing undergraduate texts. Moreover, cutting-edge examples and applications throughout the texts show the relevance of thechemistry being described to the real world. Pericyclic reactions constitute a fundamental class of organic chemistry, including such commercially important synthetic reactions as theDiels-Alder reaction. This primer gives a concise and accessible account of these reactions, enabling students to recognise the different types of pericyclic reaction and understand their application in organic synthesis.
