Reduction of oxygenated organosulfur compounds

Abstract

A comprehensive review on deoxygenation of sulfoxides to thioethers and reductive coupling of sulfonyl, sulfinyl and sulfenyl halides, sulfinates and thiosulfonates to their corresponding disulfides are discussed with different reagents and catalysts. The reported mechanisms for these transformations are also addressed.
