| 摘 要： | 5-氢-1,4,6,9-四氧-5-膦螺环4.4]壬烷2是合成有机磷阻燃剂的重要原料.其合成方法虽有一些报道,但尚未见2-氯-1,3,2-二氧膦杂环戊烷1与乙二醇反应的合成路线.我们用1、乙二醇及三乙胺以等摩尔比反应,发现2的收率很低,主要得到环状二亚磷酸酯3,将3再与乙二醇反应,很容易转化成2,反应式如下:

| Abstract: | 5-Hydro-1 , 4,6,9-tetraoxa-5-phosphaspiro4. 4]nonane 2 was prepared by the reaction of 2-chloro-1 , 3,2-dioxaphospholane with glycol in good purity and yield. Compound 2 reacted with pentamethylsilylamine or trimethyl silyl chloride to give glycol disilyl ether, silyl phosphite and cyclic diphosphite. |
