Paragraph 0148; 0156; 0157, (2017/02/28)
The present disclosure is directed to methods for dehydrogenatively coupled hydrosilanes and alcohols, the methods comprising contacting an organic substrate having at least one organic alcohol moiety with a mixture of at least one hydrosilane and sodium and/or potassium hydroxide, the contacting resulting in the formation of a dehydrogenatively coupled silyl ether. The disclosure further described associated compositions and methods of using the formed products.

Sodium Hydroxide Catalyzed Dehydrocoupling of Alcohols with Hydrosilanes
Toutov, Anton A.,Betz, Kerry N.,Haibach, Michael C.,Romine, Andrew M.,Grubbs, Robert H.
supporting information, p. 5776 - 5779 (2016/11/29)
An O-Si bond construction protocol employing abundantly available and inexpensive NaOH as the catalyst is described. The method enables the cross-dehydrogenative coupling of an alcohol and hydrosilane to directly generate the corresponding silyl ether under mild conditions and without the production of stoichiometric salt byproducts. The scope of both coupling partners is excellent, positioning the method for use in complex molecule and materials science applications. A novel Si-based cross-coupling reagent is also reported.
PRODUCTION METHOD FOR ALKOXYSILANES
-
Paragraph 0096; 0097; 0118, (2016/01/30)
Provided is a method for efficiently producing alkoxysilanes that are useful as various functional chemicals. In order to produce alkoxysilanes efficiently, an ethoxy- or methoxysilane and an alcohol are caused to react using, as a catalyst, for instance an inorganic solid acid having a regular-pore and/or layered structure. Zeolites, montmorillonites or the like can be used as the inorganic solid acid. When a zeolite is used as the catalyst, the silica/alumina ratio of the zeolite ranges preferably from 5 to 1000. The reaction can be promoted through irradiation of microwaves.

Catalytic reduction of benzoate esters and lactones in the presence of PhMeSiH2 and a titanocene-based catalyst
Shu, Ronghua,Harrod, John F.,Lebuis, Anne-Marie
, p. 489 - 495 (2007/10/03)
PhMeSiH2 reduces ethyl benzoate in the presence of a Cp2TiMe2 (Cp = η5-cyclopentadienyl) catalyst to give PhMeSi(OEt)(OCH2Ph) (1). Small to moderate amounts of toluene are also produced, depending on the reaction conditions. Under 40 psi of H2 the same reaction gives quantitative reduction of the ester to toluene. PhCHO is reduced, under the same conditions as the ester, to a mixture of PhMeSi(OCH2Ph)2 and toluene in proportions similar to that observed with the ester. A stoichiometric reaction of PhMeSiH2, PhCOOEt, and Cp2TiMe2 resulted in the formation of known [Cp2Ti(OEt)]2 (2) in 75% isolated yield. A mechanism is proposed in which the C=O of the ester inserts into a Ti-H bond. A Ti-mediated transfer of the ethoxy group from the resulting (α-ethoxy)benzyloxytitanium intermediate to silicon produces PhMeSi(OEt)H and PhCHO. 1 is generated via hydrosilation of PhCHO by PhMeSi(OEt)H. Both β- and γ-butyrolactones react with PhMeSiH2 in the presence of a catalytic amount of Cp2TiMe2 to produce copolymers -[O-PhMeSi-O(CH2)3CHR]n- (R = H, 3; R = Me, 4) (Mw ≈ ×103; Mw/Mn ≈ 1.3). A mechanism analogous to that proposed for the ethyl benzoate reduction is proposed. A reaction of PhMeSiH2 and γ-butyrolactone with a stoichiometric amount of Cp2TiMe2 in the presence of tetrahydofuran (THF) produces Cp2Ti(μ-H)(μ-η1,η5-C 5H4)Ti(OC4H8)Cp (5) (65% isolated yield) whose structure is determined by X-ray crystallography.
