## Abstract

A vinyl- or allyl-containing compound represented by following Formula (3): wherein R2, R3, R4, R5, and R6 each represent hydrogen atom or a nonmetallic atom-containing group; R7 represents a nonmetallic atom-containing group; Y represents a group selected from the group consisting of —Si(R8)(R9)—, —Si(R10)(R11)—O—, the left hand of which is combined with R7, and —NR12—, wherein R8, R9, R10, R11, and R12 each represent hydrogen atom or a nonmetallic atom-containing group; and “n” represents 0 or 1, is prepared by reacting a vinyl or allyl ester compound represented by following Formula (1): wherein R1 represents hydrogen atom or a nonmetallic atom-containing group; R2, R3, R4, R5, R6, and “n” are as defined above, with a compound represented by following Formula (2): R7—Y—H (2) wherein R7 and Y are as defined above, in the presence of a transition element compound.

## Claims

### Claim 1

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), R2, R3, R4, R5, and R6 are independently from one another a hydrogen atom or an alkyl group having one to three carbon atoms; R7 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(R8)(R9)— and —Si(R10)(R11)—O—, the left hand of which is combined with R7, wherein R8, R9, R10, R11, and R12 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 R1 represents an alkyl group having one to three carbon atoms or a phenyl group; R2, R3, R4, R5, R6 and n are as defined above, and a compound represented by the following Formula (2):
R7—Y—H (2)
wherein R7 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.
