摘要

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 aryla-tion,chalcogenation,and C-N cross-coupling reactions under visible light irradiation with a broad sub-strate 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.
