摘要：

采用6-311G（d）/B3LYP计算方法，通过对多个有机物和中间体的分子结构和能量的计算，探讨了如下问题：（1）Birch还原的区域选择性问题；（2）氯甲基的电子效应问题；（3）反芳香性对有机物结构影响问题；（4）多环化合物局部芳香性问题。这些计算与探讨丰富了有机化学教学内容，有利于大学生对芳香烃章节的学习。

Abstract:

By means of calculation on the molecular structures and energies of some organic compounds and intermediates based on 6-311G(d)/B3LYP method, the following questions have been discussed:(1) regioselectivity of Birch reduction; (2) electronic effect of chloromethyl; (3) effect of antiaromaticity on structures of organic compounds; (4) local aromaticity of polycyclic compounds. These calculations and discussions enrich the teaching content of organic chemistry course and are useful for college students to study aromatic hydrocarbon.
