Bipotentiometry has been found to be applicable in the oxidation with lead IV acetate of various polyenes and organosulfur compounds in trifluoroacetic acid. It is assumed that oxidation produces intermediates such as radical cations that are electrochemically reversible and capable of depolarizing electrodes. These radical cations are stabilized appreciably via charge delocalization theough conjugated double bonds, hyperconjugation, etc. The net result is the production of titration curves composed of saw tooth potential increments resulting from formation and decay of depolarizing species.
