  摘要：

  含有可聚合基团的金属醇盐通常用作溶胶-凝胶工艺和有机聚合相结合的无机-有机杂化材料的前体。在这里，我们报告了 通过 不同链长的烷基链连接到甲基丙烯酸酯基的乙酰乙酰氧基衍生物的合成 。使用NMR和FT-IR测量研究了所得分子与钛和锆的醇盐（ M （ OR ）4； M = Ti，Zr； R =乙基，丁基，异丙基）的配位。结果与双核复合物[Ti（O i Pr ）3的结构数据有关 （ EAA ）] 2（H EAA ：乙酰乙酸乙酯），是通过单晶X射线衍射得到的。研究表明，在所有情况下，β-酮酯基均充当螯合配体，从而形成可聚合的配位化合物。然而，溶液中的NMR分析表明，即使在作为副反应的温和条件下，甲基丙烯酸型单体的酯交换反应也发生，其比例取决于所使用的金属醇盐的类型。
