✦ Synopsis

The dibenzo [de; hi] naphthacenyl dication ($) and dianion (2) have been generated from a mixture of the corresponding precursor hydrocarbons.

The pmr spectra of 2 and 2 indicated that the positive and the negative charges were found to be fully delocalized over the molecules, respectively, consistent with the C2v-symmetry structures.

The pmr chemical shifts of ,$, correlate well with the Hiickel charge densities.
