borohydride in methanol under reflux through a rare aziridine to azetidine rearrangement. These findings stand in contrast to the known reactivity of the closely related N-alkylidene-(2,3-dibromopropyl)amines, which are easily converted into 2-(bromomethyl)aziridines under the same reaction conditions. A thorough insight into the reaction mechanism was provided by both experimental study and theoretical
N-亚烷基-(2,3-二溴-2-甲基丙叉基)胺和N-(2,3-二溴-2-甲基丙叉基)苄胺的合成效用是通过3-甲氧基-3-甲基氮杂环丁烷的意外合成证明的在稀有氮丙啶至氮杂环丁烷重排的回流条件下,用硼氢化钠的甲醇溶液处理。这些发现与密切相关的N-亚烷基-(2,3-二溴丙基)胺的已知反应性相反,所述N-亚烷基-(2,3-二溴丙基)胺在相同反应条件下容易转化为2-(溴甲基)氮丙啶。实验研究和理论合理性均提供了对反应机理的深入了解。
