摘　　要：将二苯二硫醚作为硫源与1-甲基-2-苯基吲哚反应合成了含杂原子环的硫醚类化合物,然后再与二芳基碘三氟甲磺酸鎓盐反应,合成了一种新的芳基硫鎓盐。采用1 HNMR、MS等技术对目标化合物进行了表征,并确定了最佳反应条件。在硫醚类化合物与二芳基碘三氟甲磺酸鎓盐的摩尔比为1∶1.2,催化剂为CuI/Cu,溶剂为1,1,2,2-四氯乙烷的反应条件下,目标化合物的产率达到了62.0%。同时,对这类结构的芳基硫鎓盐进行了紫外光固化性能测试,发现其能够在紫外光固化体系中作为阳离子光引发剂得到应用。A new kind of aryl sulfonium salts were prepared by diphenyliodonium triflate with thioether compounds which have been synthesized by reaction of diphenyl disulfide ether with 1-methyl-2-phenyl indole.The compounds are characterized by 1 HNMR and ESI TOF-MS.In addition,the optimum reaction conditions were determined.The yield of the product was up to 62%in 1,1,2,2-tetrachloroethane solvent under CuI/Cu as the catalysts,in molar ratio of 1∶1.2of thioether compounds to diphenyliodonium triflate.Further,the optical performance test of the aryl sulfur salts show that they can be applied as cationic photoinitiators in UVcuring system.
