CYCLIC VOLTAMMETRIC STUDIES FOR DIFFERENT SUBSTITUTED BENZILS
Abstract
ABSTRACT
The electroreduction of different substituted benzils was synthesized and studied in alcoholic and alkaline medium by cyclic voltammetry. In alkaline
solutions, the reduction occurs in two reversible one-electron steps producing the anion radical and the dianion. In the presence of alcohol, the
first reduction is unaffected and the second reduction wave becomes irreversible and is shifted toward positive potentials, following qualitatively
the criteria for a rapid reaction of the dianion with the proton donor. The protonation can occur through the radical anion since it is not possible to
observe the first step of the reaction to the radical anion.
