摘要:

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%。

Abstract:

A method is provided for preparing (4-hydroxyphenyl)methyl-(phenylmethyl)sulfonium hexafluoroantimonate. 4-Mercaptophenol reacted with benzyl chloride in the present of triethylamine to give 4-(benzylthio)phenol;4-(benzylthio)phenol reacted with dimethyl 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%.

Key words: UV-phocoinitiator, sulfonium salt, 4-mercaptophenol
