用推理方法导出σ络合物共振结构

A INFERENCE APPROACH TO THE GENERATION OF SIGMA COMPLEX RESONANCE STRUCTURES

本文以烷基苯亲电取代为例，采用推理方法，导出正确的每一个取代的共振结构式，并应用碳正离子稳定性原理，辨别给出较稳定的反应中间体。

In this paper,by inference,the correct resonance structures for each substitution can be come up,by an example of eclectrophilic substitution to R-Substituted bemzene and more stable reaction intermediate can be discerned and drawn from what it was applied the principles of carbon ionic stability.
