Patent ID: 7745654

Claim:
A process for the preparation of a vinyl- or allyl-containing silicon compound represented by the following Formula (3), or a divinyl-, diallyl-, trivinyl-, or triallyl-containing silicon compound, wherein, in the above Formula (3), R 2 , R 3 , R 4 , R 5 , and R 6 are independently from one another a hydrogen atom or an alkyl group having one to three carbon atoms; R 7 is a hydrocarbon group, a heterocyclic group, an acyl group, a halogen atom, a substituted oxy group, or a hydroxyl group; Y represents a group selected from the group consisting of —Si(R 8 )(R 9 )— and —Si(R 10 )(R 11 )—O—, the left hand of which is combined with R 7 , wherein R 8 , R 9 , R 10 , R 11 , and R 12 are independently from one another a hydrogen atom, a hydrocarbon group, a heterocyclic group, an acyl group, a halogen atom, a substituted oxy group, or a hydroxyl group; and n is 0 or 1, said process comprising the step of: carrying out a reaction between a vinyl or allyl ester compound represented by the following Formula (1): wherein R 1 represents an alkyl group having one to three carbon atoms or a phenyl group; R 2 , R 3 , R 4 , R 5 , R 6 and n are as defined above, and a compound represented by the following Formula (2): R 7 —Y—H (2) wherein R 7 and Y are as defined above; wherein the reaction is carried out in the presence of an iridium compound; and wherein a divinyl- or diallyl-containing silicon compound is prepared when the compound represented by Formula (2) is disubstituted and a trivinyl- or triallyl-containing silicon compound is prepared when the compound represented by Formula (2) is monosubstituted.
