Available in PDF, EPUB and Kindle. Book excerpt: Organic Chemistry, Volume 4: Fundamentals of Carbanion Chemistry provides information pertinent to carbanion chemistry. This book explores several topics, including carbonium ions, carbanions, carbenes, and carbon radicals. Comprised of six chapters, this volume starts with an overview of the variation of the kinetic and thermodynamic acidities of carbon acids with substituents and environments. This text then explores the methods of carbanion stabilization by substituents and discusses the various types of stabilization. Other chapters explain the stereochemistry of hydrogen–deuterium exchange and examine the stereochemistry of substitution reactions of organometallic compounds. This book discusses as well the structure and immediate environment of reaction intermediates through the use of stereochemical techniques. The final chapter considers the unsaturated anionic rearrangements of carbanions, carbonium ions, as well as carbon radicals and other rearrangements. Chemists, organic chemists, researchers, and graduate students interested in the field of carbanion chemistry will find this book extremely useful.

Download or read book Ylid Chemistry written by A.W. Johnson and published by Elsevier. This book was released on 2012-12-02 with total page 399 pages. Available in PDF, EPUB and Kindle. Book excerpt: Organic Chemistry, Volume 7: Ylid Chemistry focuses on the physical and chemical properties of ylids. This book discusses the Wittig synthesis of olefins, which involves the reaction between carbonyl compounds and phosphonium ylids. Organized into two parts encompassing nine chapters, this book starts with an overview of the definition of ylids as a substance in which a carbanion is attached directly to a heteroatom transporting a high degree of positive charge. This text then examines the unique stabilization that afforded the carbanions by the presence of the adjacent 'onium atom group, which is the special characteristic of ylids. Other chapters consider the general structure of phosphonium ylids, which virtually has no limitation on the nature of the X groups on phosphorus. This book discusses as well the Wittig reaction involving a condensation-elimination between a phosphonium ylid and ketone. The final chapter deals with the various aspects of the chemistry of sulfur ylids. This book is a valuable resource for chemists.

Download or read book Reaction Mechanisms in Organic Synthesis written by Rakesh Kumar Parashar and published by John Wiley & Sons. This book was released on 2013-04-02 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: Organic chemistry is a core part of the chemistry curricula, andadvanced levels texts often obscure the essential frameworkunderlying and uniting the vast numbers of reactions as a result ofthe high level of detail presented. The material in this book iscondensed into a manageable text of 350 pages and presented in aclear and logical fashion, focusing purely on the basics of thesubject without going through exhaustive detail or repetitiveexamples. The book aims to bridge the gap between undergraduateorganic chemistry textbooks and advanced level textbooks, beginningwith a basic introductory course and arranging the reactionmechanisms according to an ascending order of difficulty. As such,the author believes the book will be excellent primer for advancedpostgraduates Reaction Mechanisms in Organic Synthesis is written fromthe point of view of the synthetic organic chemist, enablingstudents and researchers to understand and expand on reactionscovered in foundation courses, and to apply them in a practicalcontext by designing syntheses. As a further aid to the practicalresearch student, the content is organized according to theconditions under which a reaction is executed rather than by thetypes of mechanisms. Particular emphasis is placed on controllingstereospecificity and regiospecificity. Topics covered include: Transition metal mediated carbon-carbon bond formationreactions Use of stabilized carbanions, ylides and enamines forcarbon-carbon bond formation reactions, Advanced level use of oxidation and reduction reagents insynthesis. As a modern text, this book stands out from its competitors dueto its comprehensive coverage of recently published research. Thebook contains specific examples from the latest literature,covering modern reactions and the latest procedural modifications.The focus on contemporary and synthetically useful reactionsensures that the contents are specifically relevant and attractiveto postgraduate students and industrial organic chemists.

Download or read book Carbanion Chemistry written by R. Bates and published by Springer. This book was released on 2012-01-19 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book was prepared with the idea of collecting some of the multitudinous new literature on carbanions and pre- senting it along with the fundamentals of carbanion chemi- stry. Some 400 papers from the period 1976 to 1982 have been assimilated into the book along with about an equal number of references (many to reviews) from the earlier literature. The material is organized under the headings Structures (with emphasis on the results of X-ray studies since they unambiguously show the molecular geometry), Preparations, and Reactions. Reactions, the largest topic, is divided into reactions with electrophiles, eliminations, oxidations, and rearrangements. Under these headings, carbanions without resonance stabilization (0' carbanions) are generally discus- sed first, and are further subdivided into Sp3 (alkyl) followed by Sp2 (vinyl and aryl) followed by sp (acetylenic); resonance- stabilized (n) hydrocarbon anions such as allyl and benzyl follow; lastly, heteroatom-containing n carbanions such as enolates are considered. Some references to carbanion equivalents are included at the end. Tucson, Arizona U.S.A. Robert B. Bates May 1983 Craig A. Ogle Table of Contents I. Introduction 1 II. Structures . 3 1.

Download or read book Lewis Base Catalysis in Organic Synthesis written by Edwin Vedejs and published by John Wiley & Sons. This book was released on 2016-07-28 with total page 1488 pages. Available in PDF, EPUB and Kindle. Book excerpt: This three-volume set represents the first comprehensive coverage of the rapidly expanding field of Lewis base catalysis that has attracted enormous attention in recent years. Lewis base catalysis is a conceptually novel paradigm that encompasses an extremely wide variety of preparatively useful transformations and is particularly effective for enantioselectively constructing new stereogenic centers. As electron-pair donors, Lewis bases can influence the rate and stereochemical course of myriad synthetic organic reactions. The book presents the conceptual/mechanistic principles that underlie Lewis base catalysis, and then builds upon that foundation with a thorough presentation of many different reaction types. And last but not least, the editors, Prof. Edwin Vedejs and Prof. Scott E. Denmark, are without doubt the leaders in this emerging field and have compiled high quality contributions from an impressive collection of international experts.

Book excerpt: Volume 1 provides a detailed survey of reactions that entail the 1,2-addition of nonstabilized carbanion equivalents of carbonyl, imino and thiocarbonyl functionality. Emphasis has been placed on those reagents that result in highly selective addition reactions. Methods are reported to select, for example, one carbonyl group over another in the same molecule, or to add preferentially a fragment to one (enantiotopic of diastereotopic) face of a carbonyl group. Processes that result from an initial addition to the C=X functional group, for example alkenations and rearrangements, are also covered in this volume.
