Abstract
Platinum-styrene complexes are prepared by reacting a platinum halide with styrene or substituted styrenes in the presence of a basic material for a sufficient amount of time to form a complex having more than one and less than four gram atoms of halogen per gram atom of platinum. These platinum-styrene complexes may be used to promote the addition of organosilicon compounds having at least one .tbd.SiH group per molecule to a compound containing aliphatic unsaturation.
Claims6
A process for preparing a platinum catalyst for hydrosilation reactions which comprises reacting a platinum halide with an olefinic hydrocarbon selected from the group consisting of styrene and ring substituted styrenes in the presence of a basic material for sufficient time to form a platinum complex having more than one but less than 4 gram atoms of halogen per gram atom of platinum.
