Popis:	1. 11,12,15,16-Tetrahydro-12,15-dioxo-2,3;6,7-dibenzo-13,14;2,3-naphthotriptycene (IV), 2,15-dihydro-12,15-dioxo-2,3;6,7-dibenzo-13,14; 2,3-naphthotriptycene (III), and the corresponding hydroquinone (I) were produced for the first time; the latter is readily oxidized and characterized in the form of the diacetate. 2. The quinone (III) is reduced in dimethylformamide medium against a background of 0.1 N KNO3, forming two waves with half-wave potentials 814 and 1330 mV. 3. Annelation in the quinoid portion of the molecule reduces the stability of the semiquinone.
