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) [(C 8 H 12 irCI] 2 [(p-cymene)RuCl 2 ] 2 ; and (C3) Pd/C. The initial organosilicon compound (A) has the general formula HO-Si(R) 2 - [Si(R) 2 O] a -OSi(R) 2 -Y and the organosilanol compound has the general formula HO-Si(R)2- [Si(R) 2 O] 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.

Abstract: This disclosure provides a method of preparing a silanol-functional organosilicon compound with a cytochrome P450 variant that facilitates the oxidization of a silyl hydride group to a silanol group in the presence of oxygen. The method includes combining the cytochrome P450 variant and an organosilicon compound having at least one silicon-bonded hydrogen atom to give a reaction mixture and exposing the reaction mixture to oxygen to oxidize the organosilicon compound, thereby preparing the silanol-functional organosilicon compound. Cytochrome P450 variants suitable for use in the method are also disclosed, along with methods for engineering and optimizing the same. Nucleic acids encoding the cytochrome P450 variants and compositions, expression vectors, and host cells including the same are also disclosed.

Abstract: A method is useful for preparing alkylalkoxysilanes, such as alkylalkoxysilanes, particularly dimethyldimethoxysilane. The method includes heating at a temperature of 150°C to 400°C, ingredients including an alkyl ether and carbon dioxide, and a source of silicon and catalyst. The carbon dioxide eliminates the need to add halogenated compounds during the method.
