Available in PDF, EPUB and Kindle. Book excerpt: Cycloaddition Reactions of Heterocumulenes reviews cycloaddition reactions, particularly on hetercocumulenes having "four-electron" bonds. This book discusses the chemical relationship among the various classes of heterocumulenes, including their chemical reactivity which ranges from highly reactive species to nearly inert compounds. This text also investigates the nucleophilic reactions of ketenes and isocyanates with suitable substrates, and if possible, correlates available data with the reactivity of these species in cycloaddition reactions. This book also investigates the cycloaddition reactions of carbon suboxide and other aspects of its chemistry due to the presence of many other interrelated reactions. The synthetic organic chemist should also investigate the application of isocyanate reactions associated with the cumulative double bonds. This text investigates carbodiimides as useful reagents for peptide synthesis, and notes that the stability of carbodiimides increases significantly with sterical hindrance around the cumulative double bond system. This book discusses three compounds that have a central electrophilic carbon atom, namely, carbon dioxide, carbonyl sulfide, and carbon disulfide. The book also describes the cycloaddition reactions of sulfenes, of N-sulfinylamines, of N-sulfinylsulfonamides, and of sulfurdiimides. This book can prove useful for researchers, technicians, and scientists whose works involve organic chemistry, analytical chemistry, and other related fields of chemistry.

Available in PDF, EPUB and Kindle. Book excerpt: Specialist Periodical Reports provide systematic and detailed review coverage of progress in the major areas of chemical research. Written by experts in their specialist fields the series creates a unique service for the active research chemist, supplying regular critical in-depth accounts of progress in particular areas of chemistry. Fro over 90 years The Royal Society of chemistry and its predecessor, the Chemical Society, have been publishing reports charting developments in chemistry, which originally took the form of Annual Reports. However, by 1967 the whole spectrum of chemistry could no longer be contained within one volume and the series Specialist Periodical Reports was born. The Annual Reports themselves still existed but were divided into two, and subsequently three, volumes covering Inorganic, Organic, and Physical Chemistry. For more general coverage of the highlights in chemistry they remain a 'must'. Since that time the SPR series has altered according to the fluctuating degree of activity in various fields of chemistry. Some titles have remained unchanged, while others have altered their emphasis along with their titles; some have been combined under a new name whereas others have had to be discontinued. The current list of Specialist Periodical Reports can be seen on the inside flap of this volume.

Available in PDF, EPUB and Kindle. Book excerpt: Cumulenes are organic molecules with two or more cumulative (consecutive) double bonds. Their reactions often proceed at room temperature, with or without a catalyst, and are stereospecific, giving the reaction products in high yields – features characteristic of “click reactions”. Cumulenes in Click Reactions presents a comprehensive list of cumulene systems and their reactions, with an emphasis on their “click-like” nature. The chapters are structured according to the number of carbon atoms in the system, including coverage of: introduction to the chemistry of cumulenes one-carbon cumulenes: sulfines, sulfenes, thiocarbonyl S-imides, thiocarbonyl S-sulfides, and 1-aza-2-azoniaallene salts two-carbon cumulenes: carbon oxides, carbon sulfides, carbon nitrides (isocyanates, isothiocyanates, and carbodiimides), phosphaallenes, and diarsaallenes 1,2-dicarbon cumulenes: ketenes, thioketenes, ketenimines, 1-silaallenes, 1-phosphaallenes, and other metal allenes 1,3-dicarbon cumulenes: thiocarbonyl S-ylides, 2-azaallenium salts, 1-oxa-3-azoniabutatriene salts, 1-thia-3-azoniabutatriene salts, and phosphorous ylides 1,2,3-tricarbon cumulenes: allenes, butatrienes, higher cumulenes and heterobutatrienes noncarbon cumulenes: azides, triazaallenium salts, sulfur oxides, sulfur nitrides, N-sulfinylamines, sulfurdiimides, and dithionitronium cation Cumulenes in Click Reactionsis an essential guide for researchers and advanced students in academia and research working in synthetic organic, inorganic and bioorganic chemistry.

Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this edition is the same as that of the first edition, that is, to provide a deeper understanding of the structures of organic compounds and the mechanisms of organic reactions. The level is aimed at advanced undergraduates and beginning graduate students. Our goal is to solidify the student's understanding of basic concepts provided in an introduction to organic chemistry and to fill in much more information and detail, including quantitative information, than can be presented in the first course in organic chemistry. The first three chapters consider the fundamental topics of bonding theory, stereochemistry, and conformation. Chapter 4 discusses the techniques that are used to study and characterize reaction mechanisms. The remaining chapters consider basic reaction types with a broad coverage of substituent effects and stereochemistry being provided so that each reaction can be described in good, if not entirely complete, detail. The organization is very similar to the first edition with only a relative shift in emphasis having been made. The major change is the more general application of qualitative molecular orbital theory in presenting the structural basis of substituent and stereoelectronic effects. The primary research literature now uses molecular orbital approaches very widely, while resonance theory serves as the primary tool for explanation of structural and substituent effects at the introductory level. Our intention is to illustrate the use of both types of interpretation, with the goal of facilitating the student's ability to understand and apply the molecular orbital concepts now widely in use.

This book was released on 2010-10-04 with total page 348 pages. Available in PDF, EPUB and Kindle. Book excerpt: N-Heterocyclic Carbenes in Transition Metal Catalysis and Organocatalysis features all catalytic reactions enabled by N-heterocyclic carbenes (NHCs), either directly as organocatalysts or as ligands for transition metal catalysts. An explosion in the use of NHCs has been reported in the literature during the past seven years making this comprehensive overview highly apropos. The book begins with an introductory overview of NHCs which could have been subtitled all you need to know about NHCs. The main body of the book is dedicated to applications of NHCs in catalysis. In addition to the success stories of NHCs in metathesis, NHCs in cross coupling and more recently NHCs in organocatalysis, all other less publicized areas are also covered. As the success of NHCs is generally attributed to their potential to stabilize metal centres, the inclusion of a chapter on the decomposition of NHC catalysts is pertinent. The book closes with a chapter describing the applications of NHCs in industrial processes, which is the first coverage of its kind, and brings a unique industrial context to this book. Included in this book: Historical aspects of NHCs Synthetic pathways to NHC precursors, free NHCs and complexes Methods of characterisation of NHCs and related complexes Electronic properties of NHCs Steric properties of NHCs and models for their description NHCs for metathesis and cross-coupling reactions NHCs as organocatalysts NHC Transition-Metal mediated oxidations, additions to multiple bonds, polymerisation and oligomerisation, cyclisations, direct arylations, reactions involving CO, C-F and C-H bond activation, ... Decomposition of NHC-containing catalysts Industrial applications involving NHC-containing catalysts N-Heterocyclic Carbenes in Transition Metal Catalysis and Organocatalysis provides a fresh view of NHCs since most contributors are young emerging researchers in the field of homogeneous catalysis using NHCs. This group of contributors is complemented by highly established academic researchers and an industrialist. This book is comprehensive, from the basic features of NHCs to the latest advances, hence it is suitable for both the novice and the expert.

Book excerpt: The guiding principle underlying the subject matter specifically compiled in Volume 5 has been to make available to the organic chemical community a sourcebook comprehensively covering all the important &pgr;-bond-dependent transformations. Thermal, photochemical, and metal-catalyzed cycloadditions of every major type are expertly detailed by the most knowledgeable researchers in these areas. The synthetically useful electrocyclic and sigmatropic processes where alkenic centers are intimately involved in the structural change are similarly canvassed in compact detail. With added attention given to ene reactions, small-ring rearrangements, and related transition metal-associated reactions, coverage has been achieved of the full range of organic transformations directly involving the rebonding of alkenic centers. As a consequence, this volume should serve as the comprehensive sourcebook of the field for the next decade and beyond.
