    • A conventional silsesquioxane derivative has the problems that the functional groups are restricted and the chemical structure is not readily controlled and that it is expensive. The present inventors have developed a process for producing a silsesquioxane derivative at a high yield by a simple process in order to solve such problems. The novel silsesquioxane derivative according to the present invention is controlled in a structure thereof and has a functional group, which is excellent in reactivity with a target compound, to be modified. The present invention relates to a production process for a silsesquioxane derivative represented by Formula (2), characterized by using a silicon compound represented by Formula (1). In Formula (1) and Formula (2), R is a group selected from hydrogen, alkyl, aryl and arylalkyl; M is a monovalent alkaline metal atom; at least one of Y is a group represented by Formula (3), and the remainder of Y is hydrogen; R1 and R2 in Formula (3) represent the same group as defined for R; and Z is a functional group or a group having a functional group
    • 常规的倍半硅氧烷衍生物存在官能团受限并且化学结构不容易控制并且昂贵的问题。 为了解决这些问题,本发明人通过简单的工艺开发了高产率的倍半硅氧烷衍生物的制备方法。 根据本发明的新型倍半硅氧烷衍生物在其结构中被控制,并且具有与待改性的目标化合物的反应性优异的官能团。 本发明涉及由式(2)表示的倍半硅氧烷衍生物的制备方法,其特征在于使用由式(1)表示的硅化合物。 在式(1)和式(2)中,R是选自氢,烷基,芳基和芳基烷基的基团; M是一价碱性金属原子; Y中的至少一个为由式(3)表示的基团,Y的其余部分为氢; 式(3)中的R 1和R 2代表与R所定义的相同的基团; Z为官能团或具有官能团的基团
