Reaction Conditions

Reaction Steps

27.0 parts of triethoxysilane, 0.05 parts phenothiazine, and 250 ppm hexachloroplatinic acid were charged to a three-neck 100 ml round bottom flask equipped with a magnetic stirrer, thermometer, addition funnel, and water condenser with a nitrogen by-pass. 18.4 parts of allylpentachlorophenyl ether prepared as described above was then added to the dropping funnel. Flask contents were heated to 80° C. at which point the allylpentachlorophenyl ether was added dropwise keeping the exotherm below 100° C. by regulation of the addition rate. After the addition was completed (ca. 15 minutes) the total flask contents were heated at 90° C. for 30 minutes then cooled to room temperature. The flask contents were then evaporated under reduced pressure at 60° C. to yield a liquid which was subsequently vacuum distilled through a six-inch heated vigreux column at 1.0 mm Hg. 13.0 parts of 3-(pentachlorophenoxy)propyltriethoxysilane with a boiling point of 216°-245° C. at 1.0 mm Hg was obtained. The product was identified by gas chromatography, infrared and nuclear magnetic resonance spectroscopy.
