协同反应选律的一种简便推导

A Simple Deductive Method of the Selection Rules of the Concerted Reaction

本文依据FMO的吼对称性关系对电环化反应、环加成反应、a一键迁移应等三种类型的协同反应选律作了一种简便推导,直截了当,方便教学。

This paper discusses a simple deuctive method of the selection rules of the concerted reaction as electrocyclic reaction,cyclic-addition reaction,σ-bond-move reaction by means of the σu - symmetry of FMO(Frontier Molecule Orbit). This method is direct and convient to teaching.
