A four-neck flask equipped with a reflux condenser, dropping funnel, stirring rod and thermometer was charged with 41 grams of triethoxy silane (0.25 mole) and a solution of chloroplatinic (IV) acid as a catalyst, in isopropyl alcohol in an amount to provide 2×10-5 mole of platinum. To the mixture heated in an oil bath maintained at a temperature of 120° C., 14 grams of allylamine (0.25 mole) was dropwise added over one hour from the dropping funnel. The mixture was maintained at 120° C. for another period of 9 hours. At the end of the period the reaction mixture was subjected to gas chromatography analysis. It was found that gamma-aminopropyl triethoxy silane was obtained in a yield of 44% on a triethoxy silane basis, while the yield of beta-aminopropyl triethoxy silane was 10% on a triethoxy silane basis.
