摘要: 以对甲苯胺为原料,经重氮化、KI分解得到对-碘甲苯.在NH4Cl存在下,对-碘甲苯在过硫酸铵的氧化下与异丁苯反应,得到(4-甲苯基)(4-异丁基苯基)碘鎓氯.在丙酮溶剂中,(4-甲苯基)(4-异丁基苯基)碘鎓氯与六氟磷酸钾进行离子交换,得到目的产物(4-甲苯基)(4-异丁基苯基)碘鎓六氟磷酸盐.总收率为46.7%.通过紫外光谱、红外光谱和核磁共振测定,对产物进行了结构确证.

Abstract: A method is provided for preparing(4-methylphenyl)(4-isobutylphenyl) iodonium hexafluorophosphate.Toluidine was diazotized by NaNO2 and decomposed by KI to give 4-iodotoluene.4-iodotoluene reacted with isobutylbenzene in the presence of ammonium peroxodisulfate which acted as oxidant,and then reacted with ammonium chloride to give(4-methylphenyl)(4-isobutylphenyl) iodonium chloride salt.The resulting(4-methylphenyl)(4-isobutylphenyl) iodonium chloride salt reacted with KPF6 in the solution of acetone to give the(4-methylphenyl)(4-isobutylphenyl)-iodonium hexafluorophosphate,its structure was identified by UV,IR,and 1HNMR.The total yield is above 46.7%.

Key words: iodonium salt, cationic polymerization, photoinitiator
