Versuchsvorschrift

2 moles of trichlorosilane were heated in a common laboratory stirring vessel to 55° C. 0.1 ml of an 0.01 molar solution of mesityl oxide-platinum dichloride complex catalyst in acetone was added, and 2 moles of allyl methacrylate was added drop by drop under nitrogen over a period of 10 minutes with intense stirring. The internal temperature was in the meantime kept below 62° C., by external cooling. After another 8 minutes of stirring at about 60° C., no more silane hydrogen could be detected. Distillation of the product yielded 3-methacryloxypropyltrichlorosilane, (BP0.5 = 66° C.) in a yield of about 97%, with a residue of about 2%.
