Transition-Metal-Mediated C-S Bond Cleavage Reactions

Abstract

The transformations of carbon-sulfur bonds into carbon-hydrogen and carbon-carbon bonds under homogeneous conditions are discussed. The reduction methods using metal carbonyls, low-valent transition metal complexes, metal hydrides, Grignard reagents and transition metal compounds as reducing agents are presented. The reactions leadsing to the carbon-carbon bond formation by coupling with main group organometallic nucleophioles, desulfurdimerization, carbonylation and related methods are reviewed. Some other synthetically useful reactions involving the cleavage of carbon-sulfur bonds are also briefly discussed
