Abstract
A hydrosilation process where a siloxyhydride is reacted with an unsaturated reactant in the presence of a platinum catalyst and an accelerator selected from a group consisting of acetylenic alcohols and acetylenic ethers. The accelerators are especially useful for the hydrosilation of unsaturated reactants where the unsaturation is in the internal portion of the reactant's structure, for example, as in cyclopentene and cyclohexene.
