An Expeditious Entry to Benzylic and Allylic Sulfones through Byproduct-Catalyzed Reaction of Alcohols with Sulfinyl Chlorides

Abstract

In the absence of external catalysts and additives, a broad range of benzylic and allylic alcohols react with various sulfinyl chlorides to afford structurally diversified benzylic and allylic sulfones in moderate to excellent yields, and importantly, a catalysis with byproduct HCl is involved in this new protocol for sulfone synthesis.
