Versuchsvorschrift

There was added dropwise over a period of 30 minutes, 50 grams of allylmethacrylate to a mixture refluxing at 32° C. of 80.6 grams of trichlorosilane and 0.397 grams of a [SG]--S--Pt catalyst sufficient to provide 100 ppm platinum/SiH. The mixture was stirred an additional 2 hours at reflux, cooled to ambient temperature and diluted with 100 ml of hexane and filtered. There was obtained 47.7 grams of a clear, colorless oil upon concentration of the filtrate on a rotary evaporator. Based on method of preparation, NMR and VPC analysis there was obtained a 98% yield of γ-methacryloxypropyltrichlorosilane.
