芳基硫醇与各种芳基重氮四氟硼酸盐(1.2倍摩尔量),以二甲亚砜为溶剂,在空气中经可见光照射,曙红Y(5%)催化下,23℃反应5 h,生成相应的二芳基硫化物。其中22例以芳基硫醇为底物反应的收率在82%~92%,噻吩硫醇为底物(1例) Aryl thiols and various aryl diazonium tetrafluoroborates (1.2-fold molar amount), dimethylsulfoxide as a solvent, visible light irradiation in the air, eosin Y (5%) catalysis at 23 ° C. The reaction 5 h, to generate the corresponding diaryl sulfide. Among them, the yield of aryl thiol as substrate was 22% ~ 92% in 22 cases, thiophene thiol was the substrate (1 case)
