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.

method for the undirected trifluoromethylation of unactivated methylene units was developed. The reaction proceeds in aqueous acetonitrile with Grushin’s reagent, bpyCu(CF3)3, under broad-spectrum white-light irradiation. The trifluoromethylation tolerates a wide range of functional groups including ketones, esters, nitriles, amides, alcohols, and carboxylic acids. The C–H cleavage step is performed
