Abstract

Abstract: The first reduction of sulfoxides catalysed by a well‐defined manganese complex is described. A variety of sulfoxides are reduced to the corresponding sulfides in high yields using phenylsilane, diphenylsilane, and the economically feasible 1, 1, 3, 3‐tetramethyldisiloxane (TMDS) as reducing agents in the presence of a Mn‐NHC complex. The reaction is performed under air and without the need of any additive. The involvement of radicals in the catalytic reaction is probed by spin‐trap experiments. Abstract : Cheap and safe : An air‐stable manganese NHC complex displayed excellent catalytic activity in the reduction of a variety of sulfoxides to sulfides using cheap and safe tetramethyldisiloxane as reducing agent.
