Intermolecular aminotrifluoromethylation of alkenes catalyzed by [Ru(bpy)3]2+ under visible light irradiation has been explored. The present photocatalytic protocol achieves highlyefficient and regioselectivedifunctionalization of C═Cbonds, leading to a variety of β-trifluoromethylamines. The reaction is applied to “late-stage aminotrifluoromethylation” of steroid and amino acid scaffolds.

types of catalytic photoredox processes following the reductive quenching cycle (RQC) and the oxidative quenching cycle (OQC), the discussion is focused on organic transformations based on OQC, in particular the trifluoromethylation of olefinic substrates with electrophilic trifluoromethylating reagents furnishing solvolytic addition products and substitution products. It is concluded that catalytic
