Notizen: ---1,2,4,5-Tetrakis(dimethylamino)benzene (4) and 2,3,6,7-tetrakis(dimethylamino)naphthalene (5) were prepared and structurally determined. Electron-donor functions, protonation, and the geometry of intramolecular hydrogen bonds are discussed. By oxidation of 4 to its dication the benzenoid aromaticity is cancelled in favour of two independent cyanine-type units as determined by X-ray structure analysis.
