| Abstract: | The electron transfer processes in the oxidation reactions of a series of N,N-dimethyl-4-substituted anilines in liquid and gaseous phases were studied. By means of a linear regression analysis, half-wave oxidation potentials in acetonitrile. ionization potentials in the gaseous phase, substituent constants and ionization constants of conjugated acids in water or water-alcohol mixtures are related. A thermodynamic cycle allows the calculation of the solvation energies of both radical cations and parent free bases. |
