# Action of hot alkaline KMnO4 on tert butyl benzene

Side chain oxidation of aryl alkanes takes place if there is at least one alpha hydrogen present by all accounts I presumed that there would be no reaction. However the answer given was trimethyl acetic acid. Is the answer key wrong?

• Permanganate oxidises double bonds, even those in aromatic systems if you use forcing conditions. – Waylander Jul 2 '18 at 6:17
• My teacher has taught me same rxn. but acc. to him it happens only in acidic conditions not in basic medium – Harsh jain Mar 10 at 14:11
