Abstract: A method of preparing a multifunctional organosilicon compound is provided. The method comprises reacting (A) an organosilanol compound comprising a functional moiety selected from alkoxysilyl moieties and acryloxy moieties and (B) a hydridosilane compound having at least two hydrolysable groups in the presence of (C) an acetate salt. A multifunctional organosilicon compound prepared according to the method is also provided.

Abstract: Methods for preparing a catalyst precursor material from dihalo-substituted metalloids are provided. The methods In include mixing a first solution of a halogenated alkane, at least one solvent, and a first component selected from a dihalo-substituted-group-14 metalloid or an organolithium reagent in a first reaction zone. Continuously adding the first solution to a second reaction zone, and continuously adding a second solution to the second reaction zone. The second solution including at least one solvent and a second component of either the dihalo-substituted-group-14 metalloid or the organolithium reagent, the second component is different from the first component. Mixing the first solution and the second solution in the second reaction zone.

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) [(C8H12irCl]2[(p-cymene)RuCl2]2; and (C3) Pd/C. The initial organosilicon compound (A) has the general formula HO—Si(R)2—[Si(R)2O]a—OSi(R)2—Y and the organosilanol compound has the general formula HO—Si(R)2-[Si(R)2O]a—OSi(R)2—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.
