Electrochemistry of some substituted pyrroles

Abstract

A brief study of the electrochemical oxidation reaction of some α, α'-disubstituted pyrroles is presented. The oxidation reactions of these compounds are irreversible and produce a variety of soluble products which do not alter the electrode as is the case with N-substituted pyrrole derivatives which form conducting polymeric films on the electrode surface. Changes in the Epa values produced by the substituents are found to correlate with changes in the dipole moment of the molecule. © 1981 Elsevier Sequoia S.A.
