The book opens with a general overview of the constitution and reactivity of organomagnesium compounds, followed by information on handling them and on their detection and estimation. Throughout, practical aspects aswell as principles are emphasized. The chapters on the synthesis of organomagnesium compounds cover the preparation of special forms of metallic magnesium and the reaction of magnesium with substrates such as dienes, as well as the traditional preparation of Grignard reagents. Preparations by metallation and metal-halogen exchanges are also included, as are newer methods such as hydromagnesiation of alkenes and alkynes. Systematic coverage is provided on synthetically useful reactions of organomagnesium compounds. Of fundamental importance in organic synthesis are carbon-carbon bond forming reactions; additions to carbon-carbon, carbon-nitrogen, carbon-oxygen, and carbon-sulfur multiple bonds; and nucleophilic substitution at carbon. The formation of carbon-heteroatom bonds in organic compounds is described, where the heteroatom is hydrogen, nitrogen, oxygen, sulfur, or halogen. Finally, the use of organomagnesium compounds in preparing other organometalloid and organometallic compounds is outlined. Representative experimental procedures are included throughout the book, and tables with references to well-described examples are provided. - Presents a general overview of the constitution and reactivity of organomagnesium compounds - Provides coverage on the detection and estimation of organomagnesium compounds - Emphasizes practical aspects as well as principles - Covers the preparation of special forms of metallic magnesium and the reaction of magnesium with substrates such as dienes - Includes preparations by metallation and metal-halogen exchanges - Reviews new preparation methods such as hydromagnesiation of alkenes and alkynes - Outlines information on synthetically useful reactions of organomagnesium compounds - Describes the formation of carbon-heteroatom bonds in organic compounds - Addresses the use of organomagnesium compounds in preparing other organometalloid and organometallic compounds - Includes representative procedures and tables with references to well-described examples

There is a vast and often bewildering array of synthetic methods and reagents available to organic chemists today. The Best Synthetic Methods series allows any scientist who is interested in the chemical transformations of molecules to choose between all the alternatives and assess their real advantages and limitations. With the emphasis on laboratory use, these volumes represent a comprehensive and practical guide to modern synthetic organic chemistry. This book is the product of the authors many years practical experience and reading of the original literature. It contains a valuable distillation and critical evaluation of the Best Synthetic Methods for the formation and reaction of thiophenes (five membered heterocycles containing a ring sulfur) or polymers containing a thiophene functionality (thienyls). A brief review of each area is provided, but the emphasis in all cases is on describing efficient practical methods to effect the transformations described. The reader can therefore use this book to rapidly review and select the best methods of performing a synthetic conversion to create or modify a specifically substituted thiophene. Although this book contains many references to the original literature, the large number of experimental recipes enables the user to prepare a thiophene derivative without access to the original literature. These features make the handbook especially useful for physicists working in material sciences and organic/pharmaceutical chemists, who rapidly want to find out the availability of (or how to make) a specific thiophene. - Contains a systematic description and critical evaluation of the best methods for preparation of thiophenes and polymers containing thiophenes - Rapid location of methods achieved by systematic division of substituents following the periodic table - All chapters are richly illustrated by detailed experimental proceedures for the synthesis of five membered heterocycles containing sulfur

Indoles continue to be of great interest to the pharmaceutical industry and at the current time several thousand specific new derivatives are reported annually. Research has been driven by the wide range of indole derivatives which occur in nature and through the biological activity of many indole derivatives, of both natural and synthetic origin.This book provides a systematic guide to the most useful and important reactions in the field for both synthesis and synthetic modification of the indole ring. While including the most recently developed and promising methods, it also updates informationavailable on classical methods to give the reader an up-to-date and comprehensive view of the subject. The methods are illustrated by procedures drawn from the literature and by tables including examples chosen to indicate both the scope of applicabilityand variations in methodology. The organization of the book is based on the retrosynthetic concept of identifying the bond(s) formed in the reaction, which in turn identifies potential starting materials. - Includes systematic summaries of the most important methods for the construction of indoles from aromatic precursors - Discusses methods for preparing indoles by annelation of pyrroles - Covers methods for adding or modifying substituent groups, including methods for introducing the tryptamine and tryptophan side-chainsExamines reduction/oxidation reactions that are specific for indoles - Considers use of cycloaddition reactions for synthetic elaboration of indoles

A hands-on guide to assist in the planning and execution of synthetic reactions in the laboratory Despite the maturity of organic chemistry, it can still be very challenging to identify optimal methods for synthetic transformations that perform as well in real-world manufacturing processes as they do in the laboratory. This detailed and accessible guide attempts to address this vexing issue and deliver proven methodologies practicing synthetic chemists will find valuable for identifying reaction conditions that work reliably over the broadest possible range of substrates.

This text provides experimental methods for a wide range of organic reactions, systematically arranged according to reaction type, and describes the advantages and limitations of the procedures. Traditional methods to speed up organic reactions involve energy-consuming processes and costly and environmentally "unfriendly" solvents. Additionally, isolation of the product requires energy and time-consuming purification processes. A simple solution, especially for reactions involving anionic reactants, is the use of phase-transfer catalysis. Quaternary ammonium cations have the ability to transfer the anionic reactants as non-solvated ion-pairs from aqueous media into organic media. The resultant effect is to increase the rate of the organic reaction by enhancing the reactivity of the anionic species and increasing the encounter rate with the organic substrate. Side reactions are frequently eliminated so that the overall yield of the desired product is increased.Quaternary Ammonium Salts presents procedures for reducing reaction times and the need for extreme conditions, which are frequently encountered under standard reaction procedures.This is the only book to be published on quaternary ammonium salts. Best Synthetic Methods volumes allow the practicing synthetic chemist to choose between all the alternatives and assess their real advantages and limitations. Each volume of the series deals with a particular topic from a practical point of view, giving detailed examples and precise experimental directions and hints. With the emphasis on laboratory use, these volumes represent a comprehensive and practical guide to modern synthetic organic chemistry.
