One result of this resurgence of interest in the field is a rapidly escalating number of related publications.This volume is intended to provide coverage of some of the highlights of contemporary organosulfur chemistry chosen from the entire range of current activity. Organosulfur Chemistry has enjoyed a renaissance of interest over the last few years, fuelled by its impact in the areas of heterocyclic and radical chemistry, and particularly stereocontrolled processes including asymmetric synthesis.

The second revolution started in the late 1980’s as researchers developed methods to identify,purify and genetically manipulate individual enzymes - sponsible for the intricate steps leading to complex natural products.

Thus, the development of reactions in water is not only important on the laboratory scale but also for industrial applications. Finally, the performance of reactions in the absence of solvents will show practical alternatives for many reactions. The toxicity and recycling considerations have also greatly influenced the nature of the solvents used for industrial reactions. Especially with perfluorinated solvents, new biphasic catalyses and novel approaches to perform organic reactions have been developed.

. The p- formance of metal-catalyzed reactions in water for example has led to several new hydrogenation or hydroformylation procedures with important industrial applications. Modern Solvents in Organic Synthesis More than ever before, the choice of the solvent or the solvent system is ess- tial for realizing many chemical transformations with the highest efficiency.
