NEW MATERIAL:A compound shown by the formula I [R is monofunctional (substituted)hydrocarbon except ethynyl group, halogen, siloxy, or polymer residue; R' is lower alkyl]. USE:An intermediate for synthesizing various compounds. PREPARATION:A vinylsilane shown by the formula (R)3SiCH=CH2 is reacted with a vinyldisilane [e.g., CH2=CHSi(CH3)2Si(CH3)2SiCH3, etc.] shown by the formula II in a reaction solvent such as preferably an aliphatic hydrocarbon aromatic hydrocarbon, ether, etc., in the presence of a platinum catalyst (prefer ably chloroplatinic acid, alcohol modified chloroplatinic acid, or platinum vinylsiloxane). |
