Patent ID: 7102031

Claim:
A method for producing a diene compound, which comprises: inducing a Claisen rearrangement reaction of a compound having formula (2) in a mixture comprising the diene compound represented by formula (1) and the compound having formula (2), thereby producing a Claisen rearrangement reaction product comprised of the diene compound having formula (1), which is the desired rearrangement product, and the compound having formula (2) CR 1 R 2 ═CR 3 CFR 4 CR 5 R 6 OCR 7 ═CR 8 R 9 (1) CFR 1 R 2 CR 3 ═CR 4 CR 5 R 6 OCR 7 ═CR 8 R 9 (2) wherein R 1 to R 9 , which may be the same or different from each other, represent hydrogen, halogen, a monovalent hydrocarbon group, an etheric oxygen atom-containing monovalent hydrocarbon group, a halogenated monovalent hydrocarbon group or a halogenated etheric oxygen atom-containing monovalent hydrocarbon group; and separating the diene compound represented by formula (1) from the Claisen rearrangement reaction product, or converting the Claisen rearrangement reaction product into a derivative thereof and then separating the diene compound having formula (1) from the derivative of the Claisen rearrangement reaction:product, thereby producing the compound having formula (1) in high purity.
