General Description

Acetoxyethyltriethoxysilane is a chemical compound with the formula CH3CHOCH2Si(OC2H5)3. It is commonly used as a coupling agent and adhesion promoter in the production of adhesive and sealant materials. This chemical is also utilized as a surface modifier in coatings, paints, and other construction materials to improve adhesion to substrates. Acetoxyethyltriethoxysilane reacts with water to form silanol groups, which can then condense to form a siloxane polymer. It is highly reactive and should be handled with caution due to its potential to release acetic acid and other hazardous byproducts during its chemical reactions.

DEHYDROGENATIVE SILYLATION, HYDROSILYLATION AND CROSSLINKING USING PYRIDINEDIIMINE COBALT CARBOXYLATE CATALYSTS

A process for producing a silylated product comprises reacting a mixture comprising (a) an unsaturated compound containing at least one unsaturated functional group, (b) a silyl hydride containing at least one silylhydride functional group, and (c) a catalyst, optionally in the presence of a solvent, to produce a dehydrogenative silylated product, a hydrosilylated product, or a combination of a dehydrogenative silylated product and a hydrosilylated product, wherein the catalyst is chosen from a pyridine diimine cobalt dicarboxylate complex or a cobalt carboxylate compound, and the process is conducted without pre-activating the catalyst via a reducing agent and/or without an initiator or promoter compound. The present catalysts have been found to be active in the presence of the silyl hydride employed in the silylation reaction.

CATALYSIS OF HYDROSILYLATION. VII. CATALYSIS OF HYDROSILYLATION OF C=C BONDS BY RUTHENIUM PHOSPHINE COMPLEXES

A full account of the catalysis of hydrosilylation of the C=C bond in olefins, their derivatives with functional groups as well as in vinyl-trisubstituted silanes by ruthenium(II) and ruthenium(III) phosphine precursors is given.The ruthenium complexes are far more efficient catalysts for the hydrosilylation of 1-alkenes and vinyl-substituted silanes than for the substituted olefins and unsaturated esters.General features characterizing all hydrosilylation reactions catalyzed by the above catalysts are as follows: the reaction proceeds with alkoxy-substituted silanes(also with vinylsilanes) in the absence of solvent, and is enhanced (for RuII and olefins occurs exclusively) in the presence of molecular oxygen.Two general mechanisms are proposed for hydrosilylation of olefins and of vinylsilanes, respectively, which account for most of the experimental observations.
