对称二芳基碘鎓盐的合成

Synthesis of Symmetrical Diaryliodonium Salts

以芳烃、碘酸钾等为原料,用正交实验以及单因素考察的方法改进了文献的合成和后处理工艺,实验结果表明二苯基碘鎓六氟磷酸盐收率可达52.7%、4,4'-二甲基苯基碘鎓六氟磷酸盐的收率可达63.6%、4,4'-二叔丁基苯基碘鎓六氟磷酸盐收率可达68.7%、4,4'-双十二烷基苯基碘鎓六氟磷酸盐收率可达45.9%,收率均高于现有文献报道。各产物皆通过液相色谱、液质联用、核磁共振进行了结构分析与确证。

Synthesis of diaryliodonium salts from aromatics and potassium iodate was investigated by means of orthogonal and single factor methods.Results showed that the yields of diphenyl iodonium hexafluorophosphate,dimethylphenyl iodonium hexafluorophosphate,di-tert-butyl phenyl iodonium hexafluorophosphate and bisdodecylphenyl iodonium hexafluorophosphate reached 52.7%,63.6%,68.7% and 45.9%,respectively.All the products were confirmed with liquid chromatography,LC-MS and NMR.
