A green and efficient visible-light promoted aerobic oxidative C–C bond cleavage of vicinal diols in micellar medium has been developed. This protocol used graphitic carbon nitride with nitrogen vacancies (CN620) as a metal-free recyclable photocatalyst and CTAB as surfactant in water. Control experiments and the ESR results indicated that superoxide radicals and valence band holes played an important
已经开发了绿色高效的可见光促进胶束介质中邻二醇的好氧氧化C–C键裂解。该协议使用具有氮空位的石墨氮化碳(CN620)作为无

水中的表面活性剂。对照实验和ESR结果表明,超氧自由基和价带孔在反应中起重要作用。进一步的同位素实验提出了反应的β-分裂/ HAT途径和氧化/
水解/脱
水途径,这与以前的报道不同。半导体/胶束催化剂体系可以循环使用至少10次,而不会显着降低活性。此外,
