Reduction of sulfoxides catalyzed by the commercially available manganese complex MnBr(CO)5

Abstract

A new methodology for the reduction of a wide variety of aliphatic and aromatic sulfoxides catalyzed by the air-stable, cheap and commercially available manganese catalyst MnBr(CO)₅ with excellent yields is reported in this work. The catalytic system MnBr(CO)₅/PhSiH₃ is highly chemoselective, allowing the effective reduction of the SO bond in the presence of different functional groups.
