Reaction of 4-[3-(p-t-butylpheny1)-2-methylpropylthio]butan-1-ol(3e) and 5-[3-(p-t-butyl-pheny1)-2-methylpropylthio]pentan-1-ol (3f), each prepared from p-t- butylbenzoic acid, with thionyl chloride followed by treatment with silver perchlorate afforded 1-[3-(p-t-butylphenyl)-2-methylpropyl ] thiolanium perchlorate (4b) and 1-[3-(p-t-butylpheny1)-2-methylpropyl] thianium perchlorate (4d), respectively.
4-[3-(p-t-butyl-pheny1)-2-methylpropylthio]butan-1-ol(3e) 和 5-[3-(p-t-butyl-pheny1)-2-methylpropylthio]pentan-1-ol(3f)分别由对-t-丁基苯甲酸制备、用亚硫酰氯和高氯酸银处理后,分别得到 1-[3-(对-叔丁基苯基)-2-甲基丙基]噻吩高氯酸盐 (4b) 和 1-[3-(对-叔丁基苯基 1)-2-甲基丙基]噻吩高氯酸盐 (4d)。
