(4-羟基苯基)甲基苄基硫鎓六氟锑酸盐的合成及表征

Preparation and Characterization of Cationic Photoinitator (4-Hydroxyphenyl) methyl (phenylmethyl) Sulfonium Hexafluoroantimonate

以4-羟基苯硫酚和氯苄为原料、三乙胺为缚酸剂,制备了4-苄硫基苯酚;4-苄硫基苯酚在甲苯溶液中,经硫酸二甲酯甲基化制备了(4-羟基苯基)甲基苄基硫鎓硫酸盐;室温甲醇溶剂中,与六氟锑酸钠离子进行交换合成了目的产物(4-羟基苯基)甲基苄基硫鎓六氟锑酸盐。通过紫外光谱和核磁共振测定,对产物进行了结构鉴定。总收率大于75%。

A method is provided for preparing （4-hydroxyphenyl）methyl-（phenylmethyl） sulfonium hexafluoroantimonate. 4-Mercaptophenol （benzylthio） phenol; 4- （benzylthio） phenol reacted with benzyl reacted with dimet chloride in the present of triethylamine to give 4 hyl sulfate in the solution of toluene to give （4 hydroxyphenyl）methyl（phenylmethyl） iodonium sulfonium methyl sulfate salt. Then the salt reacted with KPF6 in the solution of methanol to give the （ 4-hydroxyphenyl ） methyl-（ phenylmethyl ） sulfonium hexafluoroantimonate, which structure was identified by UV and 1HNMR. The total yield is above 75
