摘要: Wittig反应是合成烯烃的经典方法,但是国内外有机化学教材中对Wittig反应的机理以及立体选择性只进行了简单介绍。本文介绍了国际上提出的几种Wittig反应机理以及对立体选择性的解释,旨在对教材中Wittig反应的知识进行补充,帮助学生理解Wittig反应机理以及立体选择性,进一步夯实学生的有机化学知识基础。

Abstract: The Wittig reaction is a well-established method for synthesizing olefins. However, undergraduate organic chemistry textbooks often provide only a cursory overview of the mechanisms and stereoselectivities associated with these reactions. This article aims to enhance the existing literature by introducing several proposed mechanisms of the Wittig reaction and their corresponding explanations for stereoselectivity. It is our hope that this discussion will aid students in understanding the mechanisms and stereoselective outcomes of the Wittig reaction, thereby reinforcing their foundational knowledge of organic chemistry.

Key words: Wittig reaction, Phosphorus ylide, Reaction mechanism, Stereoselectivity
