cyclopropyl pyrrolines resulting from SN2 ring-opening by the nucleophilic halide. In the absence of a nucleophilic counterion, the acid-catalyzed thermolyses lead to pyrroles if there can be stabilization of cationic intermediates by an electron-releasing substituent.
在用卤化铵热解时,二环丙基酮亚胺产生环丙基吡咯啉,这是由于亲核卤化物使S N 2开环而产生的。在不存在亲核抗衡离子的情况下,如果可以通过释放电子的取代基稳定阳离子中间体,则酸催化的热解会生成吡咯。
