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.

A novel cascade Cp*Rh(III)-catalyzed C-H alkylation/Cu(II)-promoted alpha-oxygenation which enabled a three-component carboxygenation of activated alkene is reported. Mild reaction conditions, broad substrate scope, and good functional group tolerance were observed. The synthetic utility of the protocol was showcased by the facile transformations of the product to a variety of structurally diverse molecules. Preliminary mechanistic studies were conducted.
