Among the various advancements in organic chemistry over the past 50 years, pericyclic reactions occupy a significant position. Extremely elegant, useful and manifold, these reactions are found in nearly every natural product synthesis and allow chemists to create complex molecules in a very simple way. As a result, the 1981 Nobel Prize was awarded to chemists who developed the theoretical background to these reactions. Based on fourteen years of teaching a graduate course, this long awaited textbook presents Diels-Alder reactions, electrocyclic reactions, sigmatropic rearrangements, ene reactions and their asymmetric versions, organometallic pericyclic reactions plus many more topics in a highly didactic way. Throughout the focus is on the important facts and aspects, with both classical and new examples explained in detail. Over 1200 references from the original literature are cited. The only up-to-date work of its kind on the market, this is an invaluable tool for students and chemistry teachers, organic chemists, and libraries. With a foreword by Nobel Laureate Roald Hoffmann.

Orbital Symmetry: A Problem-Solving Approach was born of the necessity to present to students Woodward and Hoffmann's approach to pericyclic reactions. Hence the tone is introductory, and the book is addressed primarily to an audience of advanced undergraduate and beginning graduate students. The text seeks to familiarize the readers with several of the more often encountered methods of analyzing pericyclic reactions, and these methods should enable the analysis of virtually all of them. Problem solving is the foundation of the approach. Both the introductory and theory sections include problems to prepare the reader for the more extensive chapters of problems that follow. All problems (except those in Chapter VII) are answered in the text and are fully referenced where appropriate. Many of the problems require the use of molecular models if they are to be appreciated. Prentice-Hall's ""Framework Molecular Models"" and Benjamin's ""Maruzen Models"" are best suited for the construction of the highly strained molecules often encountered in the problems, and their use is recommended.

Writing Reaction Mechanisms in Organic Chemistry, Second Edition, is an invaluable guide to charting the movements of atoms and electrons in the reactions of organic molecules. Miller and Solomon illustrate that understanding organic reactions is based on applying general principles rather than the rote memorization of unrelated processes, and, in turn, emphasize that writing mechanisms is a practical method of applying knowledge of previously encountered reactions and reaction conditions to new reactions. Students and research chemists alike will find this book useful in providing a method of organizing and synthesizing an oftentimes overwhelming quantity of information into a set of general principles and guidelines for determining and describing organic reaction mechanisms. * Essential for those students who need to have mechanisms explained in greater detail than most organic chemistry textbooks provide. * Illustrated with hundreds of chemical structures * Extensively rewritten and reorganized to make the presentation and format even easier for students to use * Contains many problem sets and answers to all problems to help students work through general principles and applications * Appendixes have been added to this edition that contain easily referenced information on Lewis structures, symbols for chemical notation, and the relative acidities of common substances

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

The Conservation of Orbital Symmetry examines the principle of conservation of orbital symmetry and its use. The central content of the principle was that reactions occur readily when there is congruence between orbital symmetry characteristics of reactants and products, and only with difficulty when that congruence does not obtain—or to put it more succinctly, orbital symmetry is conserved in concerted reaction. This principle is expected to endure, whatever the language in which it may be couched, or whatever greater precision may be developed in its application and extension. The book opens with a review of the elementary aspects of the molecular orbital theory of bonding. This is followed by separate chapters on correlation diagrams, the conservation of orbital symmetry, theory of electrocyclic reactions, theory of cycloadditions and cycloreversions, and theory of sigmatropic reactions. Subsequent chapters deal with group transfers and eliminations; secondary conformational effects in concerted cycloaddition reactions; and generalized selection rules for pericyclic reactions.
