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盐反应,合成了一种新的芳基硫盐.采用1HNMR、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.

Abstract:

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 1HNMR 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 1:1.2 of 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 UV-curing system.

Key words: photoinitiators, aryl sulfonium salts, diaryliodonium triflate
