Abstract
A process and a catalytic composition for carrying out a platinum catalyzed hydrosilylation reaction between an SiH-containing material and a terminal olefin. The process of the invention involves heating the reactants in the presence of a platinum catalyst and a promoter which is a hindered amine or phosphine, or acid salt thereof, the promoter containing at least 6 carbon atoms and having the formula ##STR1## Q is N or P; when Q is N, R is H, alkyl of 1-18 carbon atoms, nonterminal alkenyl of 4-18 carbon atoms, arylalkyl of 7-25 carbon atoms, or a derivative thereof; when Q is P, R is alkyl of 1-18 carbon atoms, nonterminal alkenyl of 4-18 carbon atoms, arylalkyl of 7-25 carbon atoms, or a derivative thereof; x is 0 or 1; R' is alkyl of 1-18 carbon atoms, nonterminal alkenyl of 4-18 carbon atoms, arylalkyl of 7-25 carbon atoms, or a derivative thereof; y is 0, 1, or 2; R' is a branched group having a 2.degree. or 3.degree. carbon atom bonded directly to Q, and is alkyl of 3-18 carbon atoms, nonterminal alkenyl of 4-18 carbon atoms, arylalkyl of 7-25 carbon atoms, or a derivative thereof; z is 1, 2, or 3 and z=3-x-y; and two R' groups, two R' groups, or one R' and one R' may be taken together to constitute a divalent moiety forming a 5-7 membered ring containing a Q atom. The catalytic composition comprises a catalytically active platinum-containing material and a promoter as defined above.
