Reaction Steps

To 162 g of 1,2,4-trivinylcyclohexane there are added 4 mg of Pt in the form of a platinum-1,3-divinyl-1,1,3,3-tetramethyldisiloxane complex, the so-called Karstedt catalyst, which corresponds to the catalyst as prepared in accordance with U.S. Pat. No. 3,775,452 (issued on Nov. 27, 1973, Bruce D. Karstedt, General Electric Co.), and the mixture is heated to about 80° C. A total of 450 g of trichlorosilane are added dropwise over a period of about 2 hours, the temperature of the liquid phase slowly rising under reflux and then falling again toward the end of the reaction. The batch is boiled at reflux for an additional 1 hour and the volatile constituents are distilled off up to 100° C. at 3 mPa.s. The title substance is obtained in virtually quantitative yield (564 g).
