Abstract: A composition includes a silyl hydride (having at least one silicon-bonded hydrogen atom per molecule) and a fluorinated triarylborane Lewis acid. In the method, the Lewis acid catalyzes reaction of silicon bonded hydrogen atoms from the silyl hydride and water, thereby forming a siloxane bond in the resulting product. The composition and method can be used to form siloxane intermediates and cured networks.

Abstract: A polyfunctional organohydrogensiloxane is prepared using a fluorinated triarylborane Lewis acid as catalyst. The polyfunctional organohydrogensiloxane may be formulated into release coating compositions. Alternatively, the polyfunctional organohydrogensiloxane may be further functionalized with a curable group to form a clustered functional organosiloxane. The clustered functional organosiloxane may be formulated into thermal radical cure adhesive compositions.

Abstract: A composition and method can be used in the preparation of various siloxanes. The composition and method employ a fluorinated triarylborane Lewis acid, a hydrocarbonoxy-functional organosilicon compound, and a silyl hydride. The fluorinated triarylborane Lewis acid catalyzes reaction of a hydrocarbonoxy moiety (from the organosilicon compound) and a silicon-bonded hydrogen atom (from the silyl hydride) to form a siloxane bond.

Abstract: An indole-functionalized bisphosphoramidite is disclosed which has a certain formula. A method for preparing a rhodium-ligand complex comprises combining starting materials comprising: (I) a rhodium catalyst precursor, and (II) the indole-functionalized bisphosphoramidite; and optionally (III) a solvent.

Abstract: A process for preparing an aldehyde-functional organosilicon compound comprises: 1) combining, under conditions to catalyze hydroformylation reaction, starting materials comprising (A) a gas comprising hydrogen and carbon monoxide, (B) a vinyl-functional organosilicon compound, and (C) a rhodium/ligand complex catalyst.

Abstract: A polyether-functional organosilicon compound and method for its preparation are provided. The method produces a polyether-functional organosilicon compound having a polyether group bonded to a silicon atom via a silicon-carbon bond. The method includes alkoxylation of a carbinol-functional organosilicon compound. The carbinol-functional organosilicon compound may be prepared by hydroformylation of an alkenyl-functional organosilicon compound to produce an aldehyde-function organosilicon compound and subsequent hydrogenation of the aldehyde-functional organosilicon compound.
