✦ Synopsis

On the basis of matching theoretical working curves to experimental data for chronoamperometry of the anodic pyridination of 9,10-diphenylanthracene (DPA) in acetonitrile, Marcoux 1 criticized our assignment of the e.c.e, mechanism to this reaction and suggested that disproportionation to the dication was more likely. In order to fit the experimental data with a theoretical curve it was necessary to assume slow equilibrium (eqn. 2) where kf/k r = (4 x 103)/(1 x 109).
