Abstract
In electrochemical oxidations, the second oxidation potential of phenylenediamines (PD) varies because of hydrogen-bonding formation for PD +· with pyridines. A linear relationship was obtained for the potential shift as a function of pKa of the protonated pyridines and potential inversion could be observed. The oxidized PD+· could also form hydrogen bonding with alcohols and the shift of potential exhibits a different pattern. © 2011 American Chemical Society.
