A hydrosilation processing a silicon hydride with an unsaturated reactant in the presence of a supported bimetallic catalyst comprising an active hydrosilating metal such as platinum in elemental or compound form, and a surface segregating metal such as copper in elemental or compound form on a support.

Bimetallic platinum catalysts for hydrosilations

A hydrosilation process comprising contacting a silicon hydride with an unsaturated reactant in the presence of a platinum catalyst supported on porous aluminum oxide having an acidity of pH 2 to 7. The process is particularly 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.
