摘　　要：首次系统地研究了卤化铵催化的间氯过氧苯甲酸氧化磺酰亚胺为哑嗪的方法.四乙基卤化铵(包括四乙基碘化铵及四乙基氯化铵)和四甲基卤化铵(包括四甲基碘化铵、四甲基溴化铵、四甲基氯化铵)被首次应用于催化氧化一系列磺酰亚胺为相应的哑嗪,可获得很高的产率.研究结果表明铵盐上氮原子的取代基对反应产率的影响是关键的,而卤素离子的影响较小.为哑嗪的合成提供了一种高产率、简便的方法.The method of oxidation of N-sulfonylimines to N-sulfonyloxaziridines with m-chloroperbenzoic acid catalyzed by ammonium halides was systematically investigated for the first time. Tetraethylammonium halides（Et_4NI or Et_4NCl） and tetramethylammonium halides（Me_4NI, Me_4NBr or Me_4NCl） were firstly used to catalyze the oxidation of a series of N-sulfonylimines to the corresponding N-sulfonyloxaziridines in excellent yields. The experimental results showed that the alkyl group of the ammonium had significant influence on the reaction, whereas the halide ions had lesser influence on the reaction. Thus the research has provided a simple procedure for the preparation of oxaziradine with excellent yields.
