Results of single sweep triangular wave cyclic voltammetric studies on some substituted anilines in acetonitrile are reported. It has been found that, while the first reduction steps of nitroanilines are reversible that of chloroaniline is irreversible. The second reduction steps were found to be irreversible and the overall picture emerged of a multistep process involving reversible charge-transfer steps followed by an irreversible chemical reaction.

Tetraethylammonium Perchlorate

Electrochemical behaviour of salicylidene-2-aminopyridine has been investigated in 0.1 M tetraethylammonium perchlorate–dimethylformamide solutions by cyclic voltammetric and convolution potential sweep voltammetric methods. It was found that the depolarizer exhibits two well-defined diffusion-controlled irreversible one-electron waves. The cyclic voltammetric characteristics and the convolution, deconvolution, and logarithmic convolution analyses reveal that salicylidene-2-aminopyridine in such conditions follows a set of two one-electron transfer reactions each followed by an irreversible chemical reaction. The values of the first-order rate constant of the irreversible chemical reaction and E1/2 were computed.
