用电荷密度拓扑分析方法对烯酮与亚甲胺环加成反应的IRC途径上过渡态附近相应构型进行了研究,得出该反应是以协同、非同步方式进行,在过渡态,C_2-N_1键已基本上形成,而C_4-C_3之间只有弱的闭壳层相互作用。
The corresponding configuration near the transitional state in the IRC pathway of the enone-memene cycloaddition reaction was studied by charge density topological analysis. The results showed that the reaction was carried out in a synergistic and asynchronous manner. In the transition state, N_1 bond has basically formed, while only a weak closed shell between C_4-C_3 interaction.
