对共轭烯烃加成特点的理论解释

A Theoretical Explanation About The Feature of Conjugated Olefines Addition

本文通过对前线分子轨道的能量、反应时的动态效应以及反应过程中的活化过渡态的分析,解释了共轭烯烃比隔离烯烃更易亲电加成的原因。此外,又用代基当量法、HMO 法和前线分子轨道理论解释了共轭烯烃既可1,2加成,又可1,4—加成的特性。

The reason that conjugated olefines can do electrophilic addition easilythan isolated olefines does is explained in this Paper through analysisesto the energy of Frontier Molecular Orbital,Dynamic effect of Chemicalreaction and transition state of activate during reaction.On the other hand,the feature that conjugated olefiones Perform both 1,2—addition and 1,4—addition is studied as well by Equivalent of Substituing group method HMOmethod and Frontier Molecular Orbital theory.
