Silicon compound and a production process for silicon compound

摘要

The object of the present invention is to provide a new kind of silicon compound having an ester-type organic functional group and a new method for providing a T₈-silsesquioxane compound having a hydroxyl group by using said silicon compound as the starting material. A silicon compound represented by formula (1) is obtained through the production process characterized by using a silicon compound represented by formula (2). wherein: in formula (1), each of seven R¹ group is independently selected from the group consisting of hydrogen, alkyl, substituted or unsubstituted aryl, and substituted or unsubstituted arylalkyl and A² is a hydroxyl-terminal organic functional group, and in formula (2), each of R¹ group is the same as R¹ in formula (1), and A¹ is an organic functional group containing an acyloxy group.
