Generation and trapping of 1,4-diphenyl-2,3-naphthaquinone
Abstract
Lead tetra-acetate oxidation of 1,4-diphenyl-2,3-dihydroxynaphthalene normally results in oxidative trimerisation but this process is suppressed and the intermediate 2,3-naphthaquinone trapped by corresponding oxidation in butadiene at –40°.
