Tri(9-anthryl)borane was successfully applied as an organophotocatalyst for the visible-light-induced trifluoromethylation of unactivated alkenes with CFI. The mild reaction conditions tolerated a variety of functional groups, and the reaction could be extended to perfluoroalkylations with CFI and CFI. Mechanistic studies revealed that the photoredox catalysis involves an oxidative quenching pathway.
