a single-electron reducing agent under photoirradiation from a blue light-emitting diode, in the presence of appropriate electron acceptors, and the resulting sulfur-centered radical species undergoes hydrogen atom abstraction. This dual-role catalysis by TBA enables regioselectivie Cα–H arylation of benzylamines, benzyl alcohols, and ethers, as well as dihydroimidazoles, with cyano(hetero)arenes in
硫代苯甲酸(TBA)在适当的电子受体的存在下,在蓝色发光二极管的光辐射下可以用作单电子还原剂,并且所得的以硫为中心的自由基物种会经历氢原子的提取。TBA的这种双重作用催化使苄胺,苄醇和醚以及二氢咪唑与氰基(杂)芳烃的区域选择性Cα–H芳基化反应具有很高的收率,而无需过渡金属光催化剂和/或合成方法精致的有机染料。
