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 T
8
-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 R
1
group is independently selected from the group consisting of hydrogen, alkyl, substituted or unsubstituted aryl, and substituted or unsubstituted arylalkyl and A
2
is a hydroxyl-terminal organic functional group, and in formula (2), each of R
1
group is the same as R
1
in formula (1), and A
1
is an organic functional group containing an acyloxy group.
