The reaction product of 6-chloro-5, 12-naphthacenequinone with 4-hydroxyazobenzene in the dried DMF in the presence of anhydrous potassium carbonate was not the anticipated 6-[4-(phenylazo) phenoxy]-5, 12-naphthacenquinone (1) under certain reaction conditions. This unknown product 2 was proved by NMR studies to be 6-(N, N-dimethylamino)-5, 12-naphathacenequinone. Its 1H and 13C NMR chemical shifts, coupling information and structure were assigned in detail. The compound 2 may be formed by the reaction of 1 and the solvent DMF.
