A simple technique for the preparation of anions of polycyclic aromatic hydrocarbons is described. 1H and 13C NMR spectra of dianions of pyrene and derivatives of pyrene are reported and discussed.The electron density is greatest at the carbon atoms in the perimeter of the dianions.The presence of an electron-donating substitutent at position 2 causes an increase in the charge at positions 1 and 3.
