and versatile approach to 1,2-diamines has been developed based on reductive coupling reactions of various imines, where perylene, an aromatic hydrocarbon, was used as a photoredox catalyst under visible light irradiation using a white light-emitting diode. The use of 1 mol % perylene enabled almost complete conversion of the imines, leading to the formation of their corresponding 1,2-diamines, which
根据各种亚胺的还原偶联反应,开发了一种简单,无金属且用途广泛的1,2-二胺方法,其中在白色光下,在可见光照射下,芳烃hydrocarbon被用作光氧化还原催化剂。发光二极管。使用1mol%的ylene能够使亚胺几乎完全转化,导致形成其相应的1,2-二胺,其以良好的产率分离。dl和内消旋二胺之间的比例取决于亚胺的取代基,范围为31:69至82:18。
