Book excerpt: Organic Chemistry, Volume 37: Reactions of Organosulfur Compounds covers the basics of organosulfur chemistry and the characteristics of organically bound sulfur, with an emphasis on reactions, particularly those of synthetic utility. The book discusses the preparation, nature, stereochemical aspects, reactions, and the kinetic and thermodynamic assessment of the stability of sulfur-containing carbanions; the preparation and reactions of sulfur ylides; and the preparation, assessment of stability, and reactions of sulfur-containing carbocations. The text also describes preparation, assessment of stability, nature, and reactions of sulfur-containing radicals, organosulfur carbenes, and carbenoids; as well as the the pericyclic reactions of organosulfur compounds. Chemists, biochemists, and students taking related courses will find the book useful.
