A method for monotrifluoromethylthiolation of arenes via palladium-catalyzed directed C–H bond activation was described. The reaction was compatible with a variety of functional groups. Initial mechanistic studies disclosed that the turnover limiting step of the catalytic cycle did not involve C–H activation.
Cp*CoIII-catalyzed directed C–H trifluoromethylthiolation using N-trifluoromethylthiodibenzenesulfonimide as an electrophilic SCF3 source is described.
