The reactivity of 2-bromomethyl-2-methylaziridines toward oxygen, sulfur, and carbon nucleophiles in different solvent systems was investigated. Remarkably, the choice of the solvent has a profound influence on the reaction outcome, enabling the selective formation of either functionalized aziridines in dimethylformamide (through direct bromide displacement) or azetidines in acetonitrile (through rearrangement
研究了2-溴甲基-2-甲基氮丙啶在不同溶剂体系中对氧,硫和碳亲核试剂的反应性。值得注意的是,溶剂的选择对反应结果有深远的影响,能够选择性地形成二甲基甲酰胺中的官能化氮丙啶(通过直接溴化物置换)或乙腈中的氮杂环丁烷(通过双环叠氮基中间体重排)。另外,通过DFT计算进一步支持了实验观察到的2-溴甲基-2-甲基氮丙啶的溶剂依赖性行为。
