Benzene can be alkylated with an alkene, hydrogen chloride and an aluminium chloride catalyst.

HCl adds to the alkene to give the chloroalkane.

The aluminium chloride abstracts Cl– form the chloroalkane to give the reactive carbenium ion (carbocation) which undergoes an electrophilic aromatic substitution reaction with benzene to give the alkyl benzene and H+.
