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.
采用聚合氮化碳（PCN）将铜催化和半导体光催化融合，用于多种类型的交叉偶联反应。该双催化体系在可见光照射下，能温和地进行 C-H 芳基化、硫代和 C-N 交叉偶联反应，具有广泛的底物范围。具有可观的位点选择性和官能团耐受性，获得了良好至优秀的产率。无金属且成本低的 PCN 光催化剂可方便地回收并重复使用多次。
