Benzene can be alkylated to cyclohexylbenzene with cyclohexane, hydrogen chloride and an aluminium chloride catalyst.

HCl adds to the Cyclohexene to give cyclohexylchloride.

The aluminium chloride abstracts Cl– form the cyclohexylchloride to give the reactive carbenium ion (carbocation) which undergoes an electrophilic aromatic substitution reaction with benzene to give cyclohexylbenzene and H+. The H+ interacts with the [AlCl4]– to regenerate HCl and AlCl3.
