In the synthesis of 2,5-bis-ethylenimino-benzoquinone from benzoquinone and ethylenimine we isolated as the main product in addition to the desired quinone a white insoluble compound: the internal salt of 2,5-bis-ethylenimino-hydroquinone. We believe this product to represent a new type of compound, since from the series of aminophenols no internal salt seems to have been described. Thus amongst other

oxidation of various hydroquinones was achieved by using copper nanoparticles entrapped in aluminum oxyhydroxide [Cu/AlO(OH)] at room temperature. Furthermore, 2,5-diamino-1,4-benzoquinones were synthesized directly from hydroquinone and amines by a one-pot procedure consisting of the copper-catalyzed aerobic oxidation of hydroquinones and the double addition of amines to the resulting quinones.
