実験手順

A three-neck flask equipped with a reflux condenser, stirring rod and thermometer was charged with 50ml of toluene as a solvent, a small amount of polymerization inhibitor, 12.6 grams of allyl methacrylate ester (0.1 mole) and one cubic centimeter of Catalyst A of Example 1 as a catalyst (10-5 mole on a platinum basis). 13.4 grams of trimethoxy silane (0.11 mole) were dropwise added in one hour from a dropping funnel. The reaction temperature was maintained at about 50° C. The reaction was further carried out for 30 minutes. The gas chromatography analysis demonstrated that gamma-methacryloxypropyl trimethoxy silane was obtained in a yield of 86% on an allyl methacrylate basis.
