Azido-difluoromethylthiolation of Alkenes with TMSN and PhSOSCFH.

An oxidative azido-difluoromethylthiolation of alkenes by employing TMSN as the azide source and PhSOSCFH as the difluoromethylthiolation reagent is reported. The present method is characterized by good functional group tolerance, broad substrate scope, and short reaction time, thereby providing an efficient access to synthetically useful β-difluoromethylthiolated azides. Mechanistic studies indicate a radical pathway involved in the reaction.
