WebA boron-catalyzed direct α-trifluoromethylthiolation of carboxylic acids was developed. Catalytically generated boron enediolates reacts with electrophilic SCF3 reagent, N-SCF3-phthalimide, to provide α-SCF3 carboxylic acids without the need of substrate pre-activation. The method is applicable to direct modification of bioactive carboxylic ... Webuoride (Table 1). We found that the formed nucleophilic amine was able to react with the electrophilic Munavalli's 24 N-tri- uoromethylthiophthalimide 2a in MeCN at room temperature
