Abstract
The formation of 9,10-bis(phenylethynyl)anthracene dianion by contact of tetrahydrofuran-d8 solution of its precursor with sodium in vacuo, is confirmed by the 1H and 13C NMR spectra and its reactivity. The excess π-charge-density distribution estimated by the CNDO/2 calculation for the dianion, is consistent with the observed 1H and 13C chemical shift values.
