Abstract
A hydrosilation process where a silicon hydride is reacted with an unsaturated reactant in the presence of a platinum catalyst and an accelerator selected from a group consisting of unsaturated secondary and tertiary alcohols and silated unsaturated secondary and tertiary alcohols. 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. The accelerators are believed to be effective in the presence or absence of oxygen.
