4-Vinylcyclohexene
4-Vinylcyclohexene is an organic compound consisting of a vinyl group attached to the 4-position of the cyclohexene ring. It is a colorless liquid. Although chiral, it is used mainly as the racemate. It is a precursor to vinylcyclohexene dioxide.Production
It is produced by 1,3-butadiene dimerizes in a Diels-Alder reaction. The reaction is conducted at 110 - 425 °C at pressures of 1.3 - 100 MPa in the presence of a catalyst. A mixture of silicon carbide and salts of copper or chromium comprises the catalyst. A competing product is 1,5-cyclooctadiene.Safety
4-Vinylcyclohexene is classified as a Group 2B carcinogen by the IARC.
