Book Description
Written by a "who is who" of leading organic chemists, this anniversary volume represent the Organic Reactions editors' choice of the most important, ground-breaking and versatile reactions in current organic synthesis. The 15 reaction types selected for this volume include reactions for carbon-carbon bond formation, cross-coupling reactions, hydro- and halofunctionalizations, among many others. In line with the successful recipe of the series, each chapter is focused on a single reaction, discussing its mechanism and stereochemistry, scope and limitations, applications to synthesis, comparison with other methods, and experimental procedures. Each chapter concludes with a tabular survey of selected key application examples, complete with reported reaction conditions and yields, to serve as a quick reference guide for synthesis planning.

Book Description
Since the publication of Organic Syntheses Based on Name Reactions and Unnamed Reactions, as Volume 11 in the Tetrahedron Organic Chemistry series, there has been a proliferation of newly discovered Name Reactions in the field of organic chemistry. Hence, this, the second edition of this title has focused on the ongoing development in this area of research. The revised title, Organic Syntheses Based on Name Reactions, reflects the notion whereby many new reagents and reactions are now being referred to by their names. The inclusion of over 155 new stereoselective and regioselective reagents or reactions including asymmetric syntheses, brings the total to over 540. Features that will be invaluable to the reader include over 3000 references, a names index, reagent index, reaction index and a functional group transformation index. The latter of these indexes will allow the reader to search for conversions of one functional group to another and has proved a much utilized tool for the synthetic chemist, searching for pathways to perform synthetic procedures.

Book Description
People who attended the NATO Advanced Study Institute (ASI) entitled NEW THEORETICAL CONCEPTS FOR UNDERSTANDING ORGANIC REAC TIONS held at Sant Feliu de Gufxols on the Costa Brava of Spain had a unique experience. They have seen the evolution of the field from qualitative arguments through the generation of Potential Energy Surfaces (PES) to the use of PES in molecular dynamics. The excellent lectures that were dedicated to the various aspects of Potential Energy Surfaces clearly revealed a colossal amount of ma terial that represents our current understanding of the overall problem. It is our hope that the present volume will recreate the excitement in the readers that we all experienced during the meeting in Spain. One can say, without too much exaggeration, that chemistry has become and exercise on potential energy surfaces (PES). Structural (position of the energy minima), spectroscopic (vicinity around the minima), and reactivity (reaction path along the surface) properties may be determined from the analysis of PES. New theoretical tools, together with recent developments in computer technology and programming, have allowed to obtain a better knowledge of these surfaces, and to extract further chemical information from them, so new horizons have been added to Theoretical Organic Chemistry.

Book Description
Synthetically useful organic reactions or reagents are often referred to by the name of the discoverer(s) or developer(s). Older name reactions are described in text books, but more recently developed synthetically useful reactions that may have been associated occasionally with a name are not always well known. For neither of the above are experimental procedures or references easy to find. In this monograph approximately 500 name reactions are included, of which over 200 represent newer name reactions and modern reagents. Each of these reactions are extremely useful for the contemporary organic chemistry researcher in industry or academic institutions. This book provides the information in an easily accessible form. In addition to seminal references and reviews, one or more examples for each name reaction are provided and a complete typical experimental procedure is included, to enable the student or researcher to immediately evaluate reaction conditions. Besides an alphabetical listing of reactions and reagents, cross references permit the organic practitioner to find those name reactions or reagents that enable specific transformations, such as, conversion of amines to nitriles, stereoselective reduction, fluoroalkylation, phenol alkynylation, asymmetric syntheses, allylic alkylation, nucleoside synthesis, cyclopentanation, hydrozirconation, to name a few. Emphasis has been placed on stereoselective and regioselective transformations as well as on enantioselective processes. The listing of reactions and reagents is supported by four indexes.
