摘　　要：对合成Fréchet型树枝化氯代中间体(Gn-Cl)的三种方法进行了比较研究,结果表明,用Gn-1-OH与二氯亚砜在1-甲基-2-吡咯烷酮中反应,得到的Gn-Cl产率较高,反应时间较短,产物易于分离纯化。对Fréchet型树枝基元(Gn-OH)粗产物的纯化方法进行了改进,使Gn-OH的产率大为提高。Three synthesis methods of Frechet -type dendritic poly（ benzyl ethers） with chloromethyl focal point （Gn- C1） were compared by experimental research. It was a better method to synthesize Gn- C1 by the reaction of Gn-1- OH with thionyl chloride in 1 -methyl -2 -pyrrolidinone, which shortened reaction time and raised the yield. The product could be purified easily. The purification method of Frechet - type dendrons with hydroxymethyl focal point （ Gn- OH） was also improved. The yield of Gn - OH was raised substantially.
