随着倍半氧锗类化合物的合成及应用研究的日益广泛 ,含 Ge-O键的烃基锗衍生物的合成及应用研究也逐渐引起了人们的关注 ,相继合成了各种类型具有抗癌活性的含 Ge-O键的烃基锗类化合物 [1～ 3] 。但烃基锗膦酸衍生物的合成及应用研究尚未见文献报道。为了探讨该类化合物的结构及 With the research on the synthesis and application of sesquichlorogenes, the research on the synthesis and application of Ge-O-based hydrocarbyl germanium derivatives has also attracted people’s attention. Various types of compounds with anticancer activity Ge-O bond-containing hydrocarbyl germanium compounds [1-3]. However, the synthesis and application of hydrocarbyl germanium phosphonic acid derivatives have not been reported in the literature. In order to explore the structure of these compounds and
