Herein, we demonstrate a green atom-economical synthesis of benzimidazoles the flavin-photocatalysed aerobic oxidative cross-dehydrogenative coupling of toluenes and -phenylenediamines. The proposed metal-free reaction proceeds in methanol/HO under visible light irradiation by consuming only molecular oxygen from atmospheric air and produces only water as waste.
在此，我们展示了苯并咪唑的绿色原子经济性合成方法，即通过黄素光催化有氧氧化交叉脱氢偶联甲苯和 -苯二胺。所提出的无金属反应在甲醇/HO 中进行，在可见光照射下，仅消耗大气中的氧气作为唯一的氧化剂，并仅产生水作为废物。
