Reaktionsschritte

A 500 cc, 3-necked, round bottomed flask, equipped with a stirrer, thermometer, addition funnel, condenser and a nitrogen blow-by was charged with 138.6 grams of allyl methacrylate, which contained 50 ppm of hydroquinone inhibitor, 0.14 gm of Ionol™ (2,6-ditert-butyl-4-methylphenol) and 0.22 ml of a 3.8% chloroplatinic acid solution in a 1,2-dimethoxyethane/ethanol mixture. The flask contents were heated to 90° C. and dropwise addition of trichlorosilane (135.5 gm, 1 mol) over a 20 minute period with cooling gave an 85% yield of 3-methacryloxypropyltrichlorosilane.
