Direct Electrophilic (Benzenesulfonyl)Difluoromethylthiolation with a Shelf‐Stable Reagent

Abstract

The (benzenesulfonyl)difluoromethylsulfanyl (PhSO2CF2S) group is a valuable substituent with specific properties which can provide access to new applications of fluoroalkylthiolated compounds. Direct introduction of this moiety can be performed by in an electrophilic manner by using a new shelf-stable reagent, namely a (benzenesulfonyl)difluoromethanesulfenamide. Furthermore, mild magnesium-mediated reduction of the PhSO2CF2S group leads to a facile synthesis of difluoromethylthiolated molecules and their deuterated analogs.
