Group localization energy and polarographic half-wave potentials of aromatic nitro compounds

Abstract

In a number of publications it has been established that the reduction potential of aromatic compounds may be correlated with the π-electron energy change associated with the localization of electron or electrons at different positions of the molecule. Thus in the reduction of quinones the electron-localization took place at the two oxygen atoms, while in the case of aromatic hydrocarbons they were localized at the two p-carbon atoms. In the case of more complex compounds the localization may take place at certain groups of atoms undergoing reduction.
