The electrochemical reduction of the Schiff base ligands N,N'-1,2-ethylenebis(salicylideneimine) and N,N'-1,2-phenylenebis(salicylideneimine) has been investigated in DMF by cyclic voltammetry and controlled-potential electrolysis. The process involves a self-protonation mechanism whereby the two-electron reduction product, a cyclic derivtive, is formed together with the conjugate base of the substrate, as a consequence of proton transfer from the substrate itself to the basic intermediates.

Abstract
The electrochemical reduction of the Schiff base ligands N,N'-1,2-ethylenebis(salicylideneimine) and N,N'-1,2-phenylenebis(salicylideneimine) has been investigated in DMF by cyclic voltammetry and controlled-potential electrolysis. The process involves a self-protonation mechanism whereby the two-electron reduction product, a cyclic derivtive, is formed together with the conjugate base of the substrate, as a consequence of proton transfer from the substrate itself to the basic intermediates.
