A process for the production of isobutylbenzenes in particular, isobutylbenzene itself, is provided. The process is in two stages and comprises (1) reacting a vinylcyclohexane with an isoolefin of formula (R)(R.sup.1)C.dbd.C(CH.sub.3).sub.2 in the presence of a dismutation catalyst to produce an isobutenylcyclohexene and (2) contacting the isobutenylcyclohexene with a dehydroisomerisation catalyst to produce an isobutylbenzene. Examples of vinylcyclohexenes which can be used include 4-vinylcyclohexene and styrene.
