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.

The direct trifluoromethylthiolation of arenes was realized via (pentamethylcyclopentadienyl)cobalt(III)‐catalyzed C(sp2)‐H activation and coupling with AgSCF3 under the assistance of a directing group. The reaction features redox‐neutrality, mild conditions, broad substrate scope, and good functional group tolerance. Preliminary mechanistic studies have been conducted.
