Notes:
The dianions of phenanthrene and 1,2,3,4-dibenzocyclooctatetraene have been prepared by metal reduction of the neutral compounds and characterized via the study of their 1H- and 13C-NMR. spectra. A description of the charge distribution can be achieved which is consistent with both MO-models and the spin density distribution of the corresponding radical anions. Thus, the dianion of 1,2,3,4-dibenzocyclooctatetraene appears as a π-bond delocalized species having its excess charge mainly localized in the eight membered ring.
