Vinyl compounds in the diene synthesis

Communication 12. Structural orientation in the diene condensation of vinyl ethers with isoprene

  • 27 Accesses

Summary

  1. 1.

    In the diene condensation of isoprene with vinyl ethers a mixture of para and meta isomers is obtained.

  2. 2.

    For the adducts given by phenyl vinyl ether a method of separation was found, and it was shown that under the conditions investigated diene synthesis occurs with formation of para and meta isomers in relative amounts of 3∶1.

  3. 3.

    With the aid of gas-liquid chromatography it was proved that cis and trans forms are present both in the individual ethers of the methylcyclohexanols and in the mixture obtained in the diene synthesis.
