A haloorganoalkoxysilane is prepared by reacting an olefinic halide with an alkoxysilane in which the alkoxy group(s) contain at least two carbon atoms in a reaction medium to which has been added a catalytically effective amount of ruthenium-containing catalyst and a reaction-promoting effective amount of an electron-donating aromatic compound promoter. The process can be used to prepare, inter alia, chloropropyltriethoxysilane, which is a key intermediate in the manufacture of silane coupling agents.

Process for making haloorganoalkoxysilanes

Process for the manufacture of blocked mercaptosilanes

A process of preparing compounds containing silicon-carbon bonds by the hydrosilation of a hydridoalkoxysilyl reactant with an olefinic reactant comprises operating the process in the presence of a platinum catalyst and a reaction promoter comprising a weakly nucleophilic amine of the formula NZ Z Z wherein Z is an aryl, alkaryl, or aralkyl group of C to C carbon atoms, or an organosilyl substituent, SiR , wherein R is an alkyl of C to C or an aryl of C to C , Z is hydrogen, alkyl of C to C , an aryl, alkaryl, or aralkyl group of C to C carbon atoms or SiR , wherein R is as previously defined; Z is the same as Z or Z , and, optionally, two Of Z , Z and Z taken together with the nitrogen atom form an aromatic heterocyclic ring.

Promoted hydrosilation reactions

The present invention describes a method for producing epoxyorganosilicon compounds through the platinum-catalyzed hydrosilation reaction of ethylenically unsaturated epoxides and a silicon-hydride in the presence of a carboxylic acid salt. Also taught herein is the use of carboxylic acid salts in compositions of epoxyorganosilicon compounds to provide compositions of greater stability.

Process for producing epoxyorganosilicon compounds

A method is provided for preparing high purity organofunctional alkyldialkoxysilanes by reacting hydroalkyldialkoxysilanes with olefins wherein formation of undesired close-boiling by-products by an alkyl/alkoxy group exchange reaction is minimized.
