Polarographic and cyclic voltammetric behaviour of twelve titled compounds have been studied in the pH range 2.0-11.2 at dropping mercury electrode, pyrolytic graphite electrode and platinum electrode. The effect of substituents, covering wide range of Hammett substituents constant values, has been evaluated quantitatively.
