nickel-catalyzed C–Htrifluoromethylation for the synthesis of trifluoromethylated freeanilines using Togni’s reagent has been developed. This approach exhibits a good functional group tolerance, good regioselectivity, and chemoselectivity under mild conditions. The newly developed economical one-step method is a better alternative to synthesize trifluoromethylated freeanilines.
