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.

The general principles of polar rearrangements are brought together in this undergraduate chemistry text, which deals with all the major rearrangements involving electron-deficient atoms or charged intermediates. Reactions involving migration to electron-deficient carbon, nitrogen, oxygen and sulphur, and sigmatropic rearrangements involving polar species, are thus treated in a coherent and consistent manner. Clear discussions of the reaction mechanisms are followed by examples of synthetic applications providing a concise yet comprehensive account of the nature and importance of these processes.

Winner of the PROSE Award for Chemistry & Physics 2010 Acknowledging the very best in professional and scholarly publishing, the annual PROSE Awards recognise publishers' and authors' commitment to pioneering works of research and for contributing to the conception, production, and design of landmark works in their fields. Judged by peer publishers, librarians, and medical professionals, Wiley are pleased to congratulate Professor Ian Fleming, winner of the PROSE Award in Chemistry and Physics for Molecular Orbitals and Organic Chemical Reactions. Molecular orbital theory is used by chemists to describe the arrangement of electrons in chemical structures. It is also a theory capable of giving some insight into the forces involved in the making and breaking of chemical bonds—the chemical reactions that are often the focus of an organic chemist's interest. Organic chemists with a serious interest in understanding and explaining their work usually express their ideas in molecular orbital terms, so much so that it is now an essential component of every organic chemist's skills to have some acquaintance with molecular orbital theory. Molecular Orbitals and Organic Chemical Reactions is both a simplified account of molecular orbital theory and a review of its applications in organic chemistry; it provides a basic introduction to the subject and a wealth of illustrative examples. In this book molecular orbital theory is presented in a much simplified, and entirely non-mathematical language, accessible to every organic chemist, whether student or research worker, whether mathematically competent or not. Topics covered include: Molecular Orbital Theory Molecular Orbitals and the Structures of Organic Molecules Chemical Reactions — How Far and How Fast Ionic Reactions — Reactivity Ionic Reactions — Stereochemistry Pericyclic Reactions Radical Reactions Photochemical Reactions This expanded Reference Edition of Molecular Orbitals and Organic Chemical Reactions takes the content and the same non-mathematical approach of the Student Edition, and adds extensive extra subject coverage, detail and over 1500 references. The additional material adds a deeper understanding of the models used, and includes a broader range of applications and case studies. Providing a complete in-depth reference for a more advanced audience, this edition will find a place on the bookshelves of researchers and advanced students of organic, physical organic and computational chemistry. The student edition of Molecular Orbitals and Organic Chemical Reactions presents molecular orbital theory in a simplified form, and offers an invaluable first textbook on this important subject for students of organic, physical organic and computational chemistry. Further information can be viewed here. "These books are the result of years of work, which began as an attempt to write a second edition of my 1976 book Frontier Orbitals and Organic Chemical Reactions. I wanted to give a rather more thorough introduction to molecular orbitals, while maintaining my focus on the organic chemist who did not want a mathematical account, but still wanted to understand organic chemistry at a physical level. I'm delighted to win this prize, and hope a new generation of chemists will benefit from these books." -Professor Ian Fleming

Solvents other than water are used in chemical analysis, chemical manufacturing, and in specialized syntheses. This book covers the principles and uses of non-aqueous solvents at a level suitable for first or second-year undergraduates. The book first discusses the general properties of solvents, and introduces the necessary concepts for making rational choices of solvents for different applications. There is a discussion of the various chemical interactions between solvents and the substances dissolved in them, and how solvents change the course of reactions. The chemistry of 16 common solvents is discussed, emphasizing the advantages and disadvantages of each. The book concludes with an account of the chemistry of molten salts and discusses the use of low melting temperature compounds as synthetic media. The book expands on the brief treatment of non-aqueous solvents given in many textbooks while avoiding the complexities introduced in research treatises. It is the only book currently available that provides an in-depth treatment accessible to undergraduates.

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.

Intended for students of intermediate organic chemistry, this text shows how to write a reasonable mechanism for an organic chemical transformation. The discussion is organized by types of mechanisms and the conditions under which the reaction is executed, rather than by the overall reaction as is the case in most textbooks. Each chapter discusses common mechanistic pathways and suggests practical tips for drawing them. Worked problems are included in the discussion of each mechanism, and "common error alerts" are scattered throughout the text to warn readers about pitfalls and misconceptions that bedevil students. Each chapter is capped by a large problem set.

The field of asymmetric catalysis plays an increasingly large role in chemical synthesis as the demand for single-enantiomer starting materials, intermediates, and products rises. This book describes the essential aspects of enantioselective catalysis in a clear, logical fashion, with chapters organized by concept rather than by reaction type. Each concept is supported by carefully selected examples to give the reader broad exposure to a wide range of catalysts, reactions, and reaction mechanisms.
