摘要
利用AMI半经验量化方法对一系列自由基-氟取代烯烃加成反应进行了计算,并用软硬酸碱规则的理论基础-广义微扰理论对计算结果进行了处理.发现该类烯烃与自由基加成的反应活性(以活化能来表示)可由该理论得到很好的解释、同时发现影响反应活性的主要因素是路易斯酸碱对之间的共价作用,而静电作用的影响则非常小。另外还发现,对于本文讨论的烯烃分子。
In this paper the reactivity of radical -- molecular addition reaction is studied interms of AM1 semi- empirical method and the Lewis acid- base theory. The results suggest thatthe reactivity of such reactions is determined mainly by the perturbation energy between the tworeactants while the electrostatic energy between charges has only a small effect on it. In addition,it is found that there is a strong interaction between the two reaction center atoms.
