Abstract

under visible light affords trifluoromethylated benzimidazo-fused heterocycles. Two complementary protocols are established: Method A employs Togni's II under nitrogen-the first example of this catalyst-reagent combination; Method B utilizes the more economical Langlois reagent under air. The reaction features broad substrate scope and enables unprecedented seven-membered ring formation.
