Reaction Steps

A 200 ml. flask equipped with a stirrer, thermometer, dropping funnel, CO inlet tube and reflux condenser having a CO outlet tube, was flushed with carbon monoxide, charged with 1.9 milligrams of tetrarhodium dodecacarbonyl (2.5×10-6 mole), 14 grams of allylamine (0.25 mole) and 60 ml. of xylene, and heated in an oil bath maintained at a temperature of 110° C. Thereafter, 41 grams of triethoxy silane (0.25 mole) was dropwise added to the mixture from the dropping funnel over 30 minutes. The reaction was continued at a temperature of 110° C. for 2 hours under stirring and CO flush. It was revealed by gas chromatography that gamma-aminopropyl triethoxy silane was obtained in a yield of 58% on an allylamine basis, while the yield of beta-aminopropyl triethoxy silane was 4.9% on an allylamine basis.
