The Electrochemical Reduction of Azines Studied by Cyclic Voltammetry

The electrochemical reduction of a series of azines is studied by cyclic voltammetry. The reduction of azines of 1-tetralone, propiophenone, phenylbenzylketone, acetophenone, m-chloroacetophenone, and p-methoxyacetophenone proceeds in two stages: the reversible formation of a radical anion in the first stage and the irreversible formation of a dianion in the second rate-determining stage. Azines of 2-indanone and dibenzylketone demonstrate a single peak of the reduction to dianione (irreversible). The diffusion coefficients, the transfer coefficients, the electron transfer rate constants, and the Matsuda-Ayabe criteria of reversibility are determined for all these azines.

Automated summary

The electrochemical reduction of a series of azines was studied using cyclic voltammetry. Different azines showed different reduction processes, some of which were reversible and some were irreversible. Important parameters, such as diffusion coefficients, transfer coefficients, electron transfer rate constants, and the Matsuda-Ayabe criteria of reversibility, were determined for these azines through experiments and calculations.
