The most common addition reactions of benzene are hydrogenation and halogenation results the formation of Cyclohexane and benzene hexachloride respectively. Hydrogenation of benzene takes place in the presence of catalyst like nickel or palladium at 475-500K temperature. This page gives details of some reactions of benzene and methylbenzene (toluene) not covered elsewhere in this section. It deals with the combustion, hydrogenation and sulphonation of benzene and methylbenzene (toluene), and with the oxidation of side chains attached to benzene rings.
