Abstract
The electrochemical reduction of isatoic anhydride and its derivatives was studied by simultaneous electrochemical and ESR-measurements. For the first time 9 new radicals were characterized by its formal redox potentials, hyperfine coupling constants, g-factors and lifetimes. The advantage of measuring the kinetic data in stagnant and renewed electrolyte combined with accumulation of the ESR-spectra is demonstrated in the case of shortlived radicals. It is shown that the electrochemical reduction of isatoic structures follows a self protonation mechanism.
