摘要 |
It is an object to obtain from a mixture of a specific diene compound (1) and a compound (2) with the same molecular weight and molecular formula hard to separate by distillation, the diene compound (1) in high purity without using any special reagent or complicated technique. <??>Namely, the present invention provides a method of inducing the Claisen rearrangement reaction of the compound (2) in a mixture containing CR<1>R<2>=CR<3>CFR<4>CR<5>R<6>OCR<7>=CR<8>R<9> and CFR<1>R<2>CR<3>=CR<4>CR<5>R<6>OCR<7>=CR<8>R<9> and separating the diene compound (1) from a Claisen rearrangement reaction product; or converting the Claisen rearrangement reaction product into a derivative and then separating the diene compound (1) from the derivative of the Claisen rearrangement reaction product. Wherein, R<1> to R<9> each represent a fluorine atom or the like. |
