4-Vinylcyclohexene is an organic compound consisting of a vinyl group attached to the 4-position of the cyclohexene ring.
[4] It is produced by buta-1,3-diene dimerization in a Diels-Alder reaction.
[5][4] 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.
In North America this is produced by Nippon Chemical Texas Inc. in Pasadena, TX.
