Abstract

A merger of copper catalysis and semiconductor photocatalysis using polymeric carbon nitride (PCN) for multi-type cross-coupling reactions was developed. This dual catalytic system enables mild C–H arylation, chalcogenation, and C–N cross-coupling reactions under visible light irradiation with a broad substrate scope. Good to excellent yields were obtained with appreciable site selectivity and functional group tolerance. Metal-free and low-cost PCN photocatalyst can easily be recovered and reused several times.
