Abstract

Cyclic voltammetry was used to investigate the mechanism of anodic oxidation of four aromatic amines, together with the effect of the addition of bases (lutidine, sym-collidine, quinuclidine and hydroxide). Without a methoxy substituent in the para position of the phenyl group, the coupling of two radical cations occurs on the addition of weak bases, but a deprotonation is involved in the presence of hydroxide ion. This deprotonation occurs in all cases when a methoxy substituent is present on the phenyl group. © 1993.
