以二苯二硫醚为硫源,在无强碱和配体的条件下,通过碘化亚铜催化促进S—S键断裂,再与苯并五元杂环化合物反应生成了芳基硫醚,采用1H NMR和13C NMR对目标化合物进行了表征,并确定了最佳反应条件.在苯并五元杂环化合物和二苯二硫醚的物质的量比为2∶1,催化剂Cu I用量为10 mol%,溶剂为二甲基亚砜(DMSO),反应温度110℃,时间12 h时,产率达到89.9%.同时,通过高效液相色谱(HLPC)进行跟踪监测,对该反应的机理进行了探讨. Using diphenyl disulfide as sulfur source, S-S bond cleavage catalyzed by cuprous iodide catalyzed by strong base and ligand, and then reacted with benzo 5-membered heterocyclic compound to form aryl thioether , The target compounds were characterized by 1H NMR and 13C NMR and the optimum reaction conditions were determined.When the molar ratio of benzene five-membered heterocyclic compounds and diphenyl disulfide was 2:1, the catalyst Cu I dosage Was 10 mol%, and the solvent was dimethylsulfoxide (DMSO). The reaction temperature was 110 ℃ and the reaction time was 12 h, the yield reached 89.9% .At the same time, by HLPC, Mechanism is discussed.
