Seven aziridines and azetidines, either unsubstituted on ring nitrogen or bearing N-acyl (N,N-dimethylcarbamyl or propionyl) groups, were reacted with N2O5 in halogenated solvents with the following results:- the behaviour of the aziridines was highly dependent on the N-substituent, giving respectively dinitrate esters, nitramine-nitrate or predominantly uncharacterisable products, whereas the azetidines
在环氮上未取代的或带有N-酰基(N,N-二甲基氨基甲酰基或丙酰基)的七个氮丙啶和氮杂环丁烷在卤化溶剂中与N 2 O 5反应,结果如下:-氮丙啶的行为高度依赖在N-取代基上,分别得到二硝酸酯,硝酸硝胺或主要不具有特征的产物,而氮杂环丁烷在所有情况下均给出N-硝基氮杂环丁烷。据信,不同的行为是由环应变效应引起的。
