electronic nature of substituents present in 1,4-dimethoxybenzene derivatives has been found to have a profound effect on whether or not such substrates can be oxidized to diquinones using ceric ammonium nitrate (CAN). In particular, there appears to be a correlation between the Hammett σp value of a substituent and the yield of the corresponding diquinone obtained upon treatment of the dimethoxybenzene
