相转移催化反应由于具有反应速度快、操作简单、收率高和污染少等优点早就被有机化学工作者所瞩目,现在相转移催化已成为一种公认的合成技术而应用到各类有机化学反应中。目前广泛应用的相转移催化技术大致可概括为液-液相转移催化(l-l PTC)和液-固相转移催化(l-s PTC)两大类。所用的催化剂主要 Phase transfer catalysis has long been the focus of organic chemists due to its advantages of fast reaction, simple operation, high yield and low pollution. Phase transfer catalysis has become a recognized synthetic technology and applied to all kinds of organic chemistry Reaction. Currently widely used phase transfer catalytic technology can be broadly summarized as liquid-liquid phase transition catalyst (l-l PTC) and liquid-solid phase transfer catalyst (l-s PTC) two broad categories. The main catalyst used
