and aziridine is formed in 3:1 ratio. The reaction mechanism appears to involve a Michael‐type addition of the nucleophilic N1 azide atom to the olefinic double bond. In chloroform, a cycloaddition reaction takes place with the formation of a 4,5‐dihydro‐1,2,3‐triazole. The heating of dihydrotriazoles in toluene is accompanied by nitrogen elimination leading to a mixture of enamine and aziridine in 1:3
10-叠氮基乙酰基-10 H-吩噻嗪与烯烃双极性亲核试剂的反应取决于反应温度。在回流的甲苯中,以3:1的比例形成烯胺和氮丙啶的混合物。该反应机理似乎涉及亲核N 1叠氮化物原子向烯属双键的Michael型加成。在氯仿中,发生环加成反应,形成4,5-二氢-1,2,3-三唑。二氢三唑在甲苯中的加热伴随着氮的消除,导致烯胺和氮丙啶的比例为1:3。J.杂环化学.2011。
