Abstract
A method of preparing an organosilanol compound is disclosed. The method comprises reacting (A) an initial organosilicon compound and (B) water in the presence of (C) a catalyst. The catalyst (C) is selected from: (C1) [(CHirCl][(p-cymene)RuCl]; and (C3) Pd/C. The initial organosilicon compound (A) has the general formula HO—Si(R)—[Si(R)O]—OSi(R)—Y and the organosilanol compound has the general formula HO—Si(R)2-[Si(R)O]—OSi(R)—Y, where each R is an independently selected hydrocarbyl group; Y comprises a functional moiety selected from alkoxysilyl moieties, epoxide moieties, and acryloxy moieties, with the proviso that Y is other than the acryloxy moieties when the catalyst (C) is (C3) Pd/C; and subscript a is 0 or 1. The organosilanol compound prepared by the method is also provided.
