Selective C(sp2)−H Functionalization of Arenes for Amination Reactions by Using Photoredox Catalysis

Abstract Herein, we report a mild and simple method for the highly selective C(sp 2 )−H amination reaction of arenes through visible‐light‐mediated photoredox catalysis with various amines, including imidazole, triazole, and tetrazole. This procedure has broad application for a range of aromatic compounds and heterocycles.
