There is a vast and often bewildering array of synthetic methods and reagents available to organic chemists today. The Best Synthetic Methods series allows the practising synthetic chemist to choose between all the alternatives and assess the real advantages and limitations.The purpose of this book is to make it possible to rapidly locate the best methods for the preparation of a specifically substituted thiophene derivative. This is easely achieved by a systematic division in chapters by treating substituents according to the position of the atom bound to the thiophene ring in the periodic table.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.
