软硬酸碱原理与不对称烯烃的加成

Principle on Soft Hard Acids and Bases Applied in the Dissymmetric Alkene Addition

运用软硬酸碱原理讨论不对称烯烃的加成反应，指出了马氏规则在不对称烯烃加成中的本质，并对其加成反应中的几种情况进行分析。

An addition reaction about dissymmetric alkene is discussed through an application of the principle on soft hard acids and bases in the paper, which also points out the nature in the dissymmetric alkene addition reaction, and gives an analysis of several circumstances appeared in this addition reaction. Therefrom, a further understanding and knowledge of MAR′S regulation are obtained.
