Patent number: 7432387Abstract: [Problems] It is to provide a process by which an organosilicon compound having a hexafluorocarbinol group can be easily produced on an industrial scale without via a complicated production step. [Means for solving problems] The following compound represented by the formula (1) and a trialkoxysilane are subjected to hydrosilylation to obtain a compound represented by the formula (2). (In the formula, R is an alkoxy group having carbon atoms from 1 to 3.) [Effects] Since the compound obtained in the present invention is a trifunctional alkoxysilane, use of a crosslinking reaction leads to a silicone resin and a silsesquioxane. The hexafluorocarbinol group functions as an excellent alkaline water-soluble group.Type: GrantFiled: August 24, 2004Date of Patent: October 7, 2008Assignee: Toagosei Co., Ltd.Inventors: Katsuhiko Komuro, Hiroshi Suzuki
