An aromatic nucleophilicsubstitution (SNAr) reaction of p-chloronitrobenzene with N-substituted pyrrolidines under highpressure gave p-pyrrolidinonitrobenzene and ring-opening products through quaternary ammonium salt. The selectivity of dealkylation and ring-opening depends on the electronic and steric factors of N-substituents. The reactions with N-methylaziridine and N-methylazetidine gave ring-opening
对氯硝基苯与 N-取代的吡咯烷在高压下进行芳香亲核取代 (SNAr) 反应,通过季铵盐得到对-吡咯烷基硝基苯和开环产物。脱烷基和开环的选择性取决于 N 取代基的电子和空间因素。与N-甲基氮丙啶和N-甲基氮杂环丁烷的反应产生开环产物而没有提供任何脱甲基产物。
