Provides a unique summary of homologation strategies in organic synthesis Homologation Reactions presents different concepts underpinning the use of homologating reagents as well as their applications in organic synthesis. It covers in-depth discussions on the rationales governing this kind of transformations with a strong emphasis on mechanistic elements modulating critical aspects (e.g. selectivity) of the processes. In addition, this two-volume work features: Metal carbenoids, ylides, and diazo reagents Homologating agents working under nucleophilic, electrophilic, and radical regime Homologations realized on boron-containing or carbon-centered linchpins Use of highly sensitive fluorinated homologating agents Progressive homologations and the concept of assembly line synthesis Homologation processes followed by rearrangement cascades Construction of cyclic motifs and ring-expansion Homologation reactions with carbon monoxide and carbon dioxide New and/or challenging directions to expect in the future Written by an international team of leaders in the field, the book is a useful guide for designing effective transformations by using homologation reactions. It is a must-read for every synthetic chemist in academia and industry!

1. INTRODUCTION Although quite spectacular results have been obtained in the last few decades in the field of homogeneous transition metal catalyzed transformations of olefins and alkynes [1], reactions which could lead to heterocycles have been partly neglected. An obvious reason for this is that substrates containing heteroatoms such as N, 0 or S could coordinate the metal and suppress the catalytic activity. Nevertheless, some interesting early examples of transition-metal-catalyzed syntheses of heterocyclic compounds have been reported and these have been reviewed by C. W. Bird [2] . More recently the incorporation of CO , which enables esters and lactones 2 to be synthesized from olefinic starting materials, has begun to attract attention (see, for example, ref. [3]). The dominant role of palladium as the catalyst for the formation of O-containing heterocycles has been suggested to be associated with the relatively low strength of the Pd-O bond. Among the first examples of a nitrogen-containing heterocycle to be formed by homogeneous catalysis is the triazine shown in Equation 1 which is the product of the trimerization of benzonitrile in the presence of iron penta carbonyl or Raney nickel [4] .

The 105th volume in this series for organic chemists in academia and industry presents critical discussions of widely used organic reactions or particular phases of a reaction. The material is treated from a preparative viewpoint, with emphasis on limitations, interfering influences, effects of structure and the selection of experimental techniques. The work includes tables that contain all possible examples of the reaction under consideration. Detailed procedures illustrate the significant modifications of each method.

Composition modulation is a method of operating a catalytic reactor to improve catalyst activity or selectivity and has been under study for more than 25 years. In the last few years, several commercial applications have been realized and more will certainly appear. A large international research literature now exists. This book examines this literature and attempts to organize and analyze it with the intent of identifying the magnitude of improvements possible, why modulation is effective, and what questions remain unanswered. Topics include hydrogenation, oxidation, reduction, and polymerization reactions for NOX, SOX, NH3, and hydrocarbons.

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.
