WebApr 25, 2012 · Some general information on side-chain oxidation in alkylbenzenes is available at Chemguide: An alkylbenzene is simply a benzene ring with an alkyl group attached to it. Methylbenzene is the simplest alkylbenzene. Alkyl groups are usually fairly resistant to oxidation. WebOct 10, 2024 · This is known as "side chain oxidation." When a compound which has an alkyl group directly attached to an aryl group is treated with a strong oxidizing agent like potassium permanganate (KMnO 4 ) or Jones Reagent (CrO 3 /H 2 SO 4 ), the benzylic carbon is oxidized to a carboxylic acid group which remains attached to the aryl group.
