Various aromatic hydrocarbons were oxidized with aqueous hydrogen peroxide in the presence of hexafluoroacetone hydrate as catalyst to give para-quinones and/or the ring cleavage oxidation products. The regioselective oxidation of 2-methylnaphthalene to 2-methyl-1,4-naphthoquinone (vitamin K3) was studied in detail.
