An Electrophilic Hypervalent Iodine Reagent for Trifluoromethylthiolation

Abstract

Sulfur and friends: A new electrophilic hypervalent iodine reagent 1 has been developed for direct trifluoromethylthiolation. A variety of nucleophiles, including β-ketoesters, aldehydes, amides, aryl or vinyl boronic acids, and alkynes, reacted with 1 under mild conditions to give the corresponding trifluoromethylthiolated compounds in good to excellent yields.
