Reaction of cumene to form phenol
Websynthesis of phenols. In phenol: Oxidation of isopropylbenzene. Benzene is converted to isopropylbenzene (cumene) by treatment with propylene and an acidic catalyst. Oxidation yields a hydroperoxide (cumene hydroperoxide), which undergoes acid-catalyzed rearrangement to phenol and acetone.
