Abstract
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.
