Ester solvents and basic catalysts employed in an addition process

Claim 1

A PROCESS FOR PRODUCING ORGANOSILICON ADDUCTS WHICH COMPRISES (A) FORMING A REACTION MIXTURE CONTAINING (1) TRICHLOROSILANE; (2) AN UNSATURATED COMPOUND SELECTED FROM THE GROUP CONSISTING OF HYDROCARBONS, HYDROCARBONHYDROCARBONOXYSILANES THAT ARE COMPOSED ONLY OF CARBON, HYDROGEN, OXYGEN AND SILICON, HYDROCARBONHALOSILANES THAT ARE COMPOSED ONLY OF CARBON, HYDROGEN, HALOGEN, AND SILICON AND HYDROCARBONSILOXANES THAT ARE COMPOSED ONLY OF CARBON, HYDROGEN, OXYGEN AND SILICON, SAID UNSATURATED COMPOUND CONTAINING AT LEAST ONE ALIPHATIC CARBON TO CARBON MULTIPLE BOND; (3) A CATALYTIC AMOUNT OF A CATALYST SELECTED FROM THE GROUP CONSISTING OF TERTIARY AMINES AND TERTIARY PHOSPHINES, SAID CATALYST BEING FREE OF ALIPHATIC CARBON TO CARBON MULTIPLE BONDS; AND (4) A HYDROCARBYL CARBON TO CARBON MULTIPLE BONDS AND THAT IS A SOLVENT FOR TRICHLOROSILANE AND THE CATALYST AND (B) MAINTAINING THE REACTION MIXTURE AT A TEMPERATURE AT WHICH THE TRICHLOROSILANE AND THE UNSATURATED COMPOUND REACT TO PRODUCE AN ADDUCT BY THE RUPTURE OF THE HYDROGEN TO SILICON BOND OF THE TRICHLOROSILANE AND THE ADDITION OF THE HYDROGEN ATOM AND THE TRICHLOROSILYL GROUP SO FORMED TO A MULTIPLE BOND OF THE UNSATURATED COMPOUND.
