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 NZ1Z2Z3 wherein Z1 is an aryl, alkaryl, or aralkyl group of C6 to C20 carbon atoms, or an organosilyl substituent, SiR3, wherein R is an alkyl of C1 to C20 or an aryl of C6 to C 10, Z2 is hydrogen, alkyl of C1 to C20, an aryl, alkaryl, or aralkyl group of C6 to C20 carbon atoms, or SiR3, wherein R is as previously defined; Z3 is the same as Z1 or Z2, and, optionally, two of Z 1, Z2 and Z3 taken together with the nitrogen atom form an aromatic heterocyclic ring.
