ABSTRACT In the process of preparing compounds containing silicon-carbon bonds by the hydrosilation reaction of a hydrosilyl reactant with an olefinic reactant in the presence of a soluble platinum catalyst, the improvement which comprises operating the process at a temperature below 150°C and employing, as a reaction promoter, a hydrosilyl compound whereby said hydrosilyl reactant has a composition different from the composition of said promoter and whereby said promoter provides (i) a 20% increase in the amount of silicon-carbon compounds, or (ii) a 20% increase in reaction rate relative to an umpromoted reaction.
