Anilinochinone und Chinonanile aus 4,4′-Bi-(1,2-naphthochinon)

4,4-Bi-(1,2-naphthoquinone) (1) reacts with several aromatic amines to yield the anilino-quinones2 a-k. Compound2 a is characterized by the binaphthoquinone dioxime6 and the semicarbazide8. The reductive benzoylation of2 a gives the benzoylester5. The aminoquinones2 a-g can be oxidized yielding the quinone-aniles3 a-g. IR and MS spectra of2 and3 are discussed.
