Trifluoromethanesulfonyl hypervalent iodonium ylide for copper-catalyzed trifluoromethylthiolation of enamines, indoles, and β-keto esters
A novel electrophilic-type trifluoromethylthiolation reagent, a trifluoromethanesulfonyl hypervalent iodonium ylide, was designed and reacted well with various nucleophiles to afford the desired CF3S-substituted products. In situ reduction of t
