ABSTRACT OF THE DISCLOSURE Platinum-olefinic hydrocarbon complexes, e.g. platinum- styrene complexes are prepared by reacting a platinum halide with styrene or ring-substituted styrenes in the presence of a basic material for a sufficient amount of time to form a platinum-olefinic hydrocarbon, e.g. platinum-styrene, complex having more than one and less than four gram atoms of halogen per gram atom of platinum. These platinum-olefinic hydrocarbon, e.g. platinum-styrene complexes may be used to promote the addition of organosilicon compounds having at least one SiH group per molecule to a compound containing aliphatic unsaturation. Thus, the above described complex may be used in a process for the addi- tion of an organosilicon compound containing silicon-bonded hydrogen to an organic compound having carbon-carbon unsaturation which comprises forming a mixture containing the organosilicon compound having silicon- bonded hydrogen and an organic compound having carbon-carbon unsaturation. It has been found that a very small amount of the catalyst will effect the desired reaction between the silicon-bonded hydrogen compound and the unsaturated organic compound. In addition, it has been found that the catalyst retains its level of activity even after storing for pro- longed periods of time at elevated temperatures. Furthermore, the activity of the catalyst is such that silicon-bonded hydrogen containing organopolysiloxanes and vinyl containing-organopolysiloxanes can be cured very rapidly and therefore used as potting or encapsulating compositions for electrical components on assembly lines,
