In electrochemical oxidations, the second oxidation potential of phenylenediamines (PD) varies because of hydrogen-bonding formation for PD(+center dot) with pyridines. A linear relationship was obtained for the potential shift as a function of pK(a) of the protonated pyridines and potential inversion could be observed. The oxidized PD(+center dot) could also form hydrogen bonding with alcohols and the shift of potential exhibits a different pattern.
