A method for producing a silsesquioxane derivative having a functional group using a silsesquioxane derivative having Si—OH is known. However, it is not easy to produce this raw material, and when chlorosilane is used to introduce a functional group, it is necessary to treat by-product hydrogen chloride. An object of the present invention is to solve such problems of the prior art. A method for producing a silsesquioxane derivative represented by the formula (2), comprising using a silicon compound represented by the formula (1). In the formula (1), R is a group independently selected from the group consisting of hydrogen, alkyl, aryl, and arylalkyl, and M is an alkali metal atom. In the formula (2), R has the same meaning as R in the formula (1), and X is hydrogen, chlorine, a functional group or a group having a functional group. [Selection diagram] None. |
