Description

Carbene Chemistry, Second Edition discusses the developments in various areas of carbene chemistry, including the correlation of spectroscopic studies of isolated carbenes with quantum chemical calculations; new carbene precursors; differentiation of carbenes and carbenoids; and mechanisms of single and triplet carbine reactions. This book is composed of two main parts encompassing 13 chapters. The first part covers the many reactions known to transfer a formally divalent carbon fragment from one molecule to another, with special emphasis on the mechanism and a critical evaluation of the evidence for carbene intermediates. The second part examines the multitude of product-forming reactions of carbenes and carbenoids with various substrates. This part also describes the structure-reactivity relationships for both carbenes and their substrates, followed by a discussion of the applications of carbene compounds in synthetic organic chemistry. This work will be of great value to organic chemists and researchers.
