photoinduced reaction, the source of a trifluoromethyl radical as a hydrogen atom transfer reagent, and the source of a trifluoromethyl anion for functionalization. The reaction was initiated by the generation of reactive electrophilic carbon‐centered CF3 radical through photoinduced homolytic cleavage of bpyCu(CF3)3, followed by hydrogenabstraction from an unactivated C(sp3)−H bond.
