A combination of copper catalysis and semiconductor photocatalysis using polymeric carbon nitride (PCN) was developed for multi-type cross-coupling reactions. 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. The metal-free and low-cost PCN photocatalyst can be easily recovered and reused multiple times, showing good yields and functional group tolerance.
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.
