| 摘 要： | 利用系列全氟烷基磺酰亚胺盐M(NPf2)n]作为一种新型的Lewis酸催化剂，用于催化芳香化合物与等摩尔65% (m∶m)硝酸的硝化反应. 通过考察不同的催化剂、反应时间、反应温度和反应介质效应等因素对甲苯硝化的影响，以及比较1 mol% YbN(C4F9SO2)2]3催化不同结构的取代芳烃硝化反应的效果，表明全氟烷基磺酰亚胺盐不仅具有环境友好和原子经济的特点，而且是一类比常规Lewis酸更有效的、芳香化合物硝化反应的催化剂.

| Abstract: | In this paper, the metal bis(perfluoroalkyl)sulfonyl]imides M(NPf2)n] were employed for nitration of aromatic compounds with 1 equiv. of 65% (m∶m) nitric acid as novel Lewis acid catalysts. The effects of Lewis acid catalysts, reaction time, temperature and medium on nitration of toluene, as well as the catalytic performance of nitration of aromatic compounds in the presence of 1 mol% YbN(C4F9SO2)2]3 were investigated. All experimental results showed that metal bis(perfluoroalkyl)sulfonyl]imides were not only environmentally friendly and atom economic, but also more effective for aromatic nitration than conven-tional Lewis acid catalysts. |
