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

A process is disclosed for the synthesis of N-cycloalkylaminoalkylsilanes, wherein the process comprises hydrogenating the corresponding N-arylaminoalkylsilanes in the presence of a catalytically effective amount of a supported or unsupported catalyst selected from the group consisting of palladium, platinum, nickel, rhenium, rhodium, ruthenium, copper chromite, and mixtures of the foregoing.

Preparation of N-substituted aminoorganosilanes

Process for preparing silylorganomercaptans

A process is provided for preparing a bis(silylorgano)amine in which a cyanoorganosilane is reacted with hydrogen under hydrogenation conditions in the presence of a catalytically effective amount of hydrogenation catalyst selected from the group consisting of rhodium, ruthenium, palladium and platinum to produce the secondary aminoorganosilane.

Process for preparing bis(silylorgano)amines

A process is provided for preparing a primary aniinoorganosilane in which a cyanoorganosilane is reacted with hydrogen under hydrogenation conditions and in the substantial absence of water in the presence of a catalytically effective amount of sponge cobalt to produce the primary aminoorganosilane.
