PROMOTED HYDROSILATION REACTIONS

摘要

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<1>Z<2>Z<3> wherein Z<1> 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 C10, Z<2> 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; Z<3> is the same as Z<1> or Z<2>, and, optionally, two of Z<1>, Z<2> and Z<3> taken together with the nitrogen atom form an aromatic heterocyclic ring.
