双官能团修饰的新型有机锗倍半氧化物的合成

Synthesis of Novel Germanium Sesquioxides Modified by Double Function Groups

通过锗氯仿和３－烷氧羰基丙烯－２－磷酸二烷酯的反应，合成了β位置磷酰基团和羰基同时修饰的有机锗倍半氧化物，对合成方法作了一定的探讨。所有产物的结构均经过１ＨＮＭＲ、３１ＰＮＭＲ、ＩＲ和元素分析等方法证明。

A series of new germasesquioxides decorated by carbonyl and phosphonyl at βpositions were first synthesized by the reaction of trichlorogermane with O,O-dialkyl 3-alkoxycarbonylpropen-2-yl phosphonates.Their structure were characterized by 1H NMR,31P NMR ,IR and elemental analysis.
