Stable cyanomethylcyclohexadienyl anions generated in two-electron reduction of isomeric tolunitriles by potassium in liquid ammonia were detected by NMR spectroscopy. The chemical shifts in these anions were obtained from density functional (PBE/3z) quantum chemical calculations and the electron density distributions for the anions were calculated in the framework of the NBO approachat the HF/6-31+G* level of theory. The experimental and calculated delta(C) values are in good agreement. Changes in the delta(C) values on going from the starting nitriles to the corresponding anions are linearly related to the calculated pi-electron densities on the pentadienyl ring carbon atoms.
