ABSTRACT:
A hydrosilation process where a silicon hydride is reacted with an unsaturated reactant in the presence of a platinum catalyst and an unsaturated ketone accelerator. The described unsaturated ketone 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. The unsaturated ketone accelerators are effective in the absence of oxygen activation of the platinum catalyst and are synergetic with oxygen activation of platinum catalyst.
