compound. In the case of diazirine 2, 13% of (E)-1-phenyl-1-pentene resulted from the direct thermal rearrangement of diazirine without the participation of a carbene. As well, the thermal decomposition of these diazirines has been studied theoretically with ab initio and density functional methods. The experimental results are broadly in agreement with the theoretical predictions. The calculations further
在溶液中存在C(60)的条件下,研究了苯基氯重氮(1),苯基正丁基重氮(2)和2-金刚烷-2,3'-[3H]重氮(3)的热分解。C(60)探针技术表明,在分解过程中,重氮1只能生成苯基氯卡宾,重氮2则主要生成重氮中间体,重氮3则可以生成卡宾和重氮化合物的混合物。在重氮2的情况下,(E)-1-苯基-1-戊烯的13%是由重氮在没有卡宾参与的情况下直接热重排产生的。同样,已经用从头算和密度泛函方法对这些二嗪类的热分解进行了理论研究。实验结果与理论预测基本吻合。
