the formation of fluorescent syn-bimane. This work combines theoretical and experimental approaches. Our computational study supports Kosower's mechanism while introducing a crucial diaziridine intermediate. Our results suggest the rate-limiting step is the formation of a diazoketene. The reaction of 4,5-dimethyl-2,3-diazacyclopentadienone with diphenylcyclopropenone produced the unexpected unsymmetrical
我们研究了荧光顺式双烷形成的机制。这项工作结合了理论和实验方法。我们的计算研究支持 Kosower 的机制,同时引入了关键的二氮丙啶中间体。我们的结果表明限速步骤是重氮酮的形成。4,5-二甲基-2,3-二氮杂环戊二烯酮与二苯基环丙烯酮的反应产生了意想不到的不对称反-(Me,Me)(Ph,Ph)bimane。
