A method has been developed for the visible light-induced trifluoromethylation of heterocyclic compounds. A variety of electron-rich heterocycles were transformed into trifluoromethylated products by using CF3I as the trifluoromethyl radical source and Ru (bpy) 3Cl2 as the photocatalyst under mild reaction conditions. This operationally simple and eco- friendly process can introduce trifluoromethyl groups without prefunctionalization.
