有机合成中相转移催化剂的研究进展

摘要

在有机化学反应中，由于相转移催化反应产率高，反应条件温和，选择性高，操作简单，已经成为一种应用非常广泛的合成方法．在大多数文献中，相转移催化剂（PTC）是以名称来分类，本文以反应系统的状态来分类，如液—液PTC、固—液PTC、三相PTC和反相PTC．介绍了相转移催化的一些催化机理，以及近期的一些PTC．%Phase transfer catalytic reaction has following advantages:high yield,mild reaction condition, good selectivity and simple operation,so it has been applied to the organic synthesis abroad.In many documents phase transfer catalyst (PTC) is classified on its designation.But in this paper PTC is classified on the state of reaction system,for example liquid-liquid PTC,liquid-liquid PTC,three phase PTC and inverse PTC.This paper describes some PTC and mechanism of phase transfer catalysis.
