The polarographic behaviour of a series of the title compounds has been investigated in aqueous alcoholic buffered media and in DMF-0.1M-LiClO4. A mechanism interpreting the electrode process was suggested and confirmed via the identification of CPE products, the use of models and the Hamett's σ-E1/2 relationship. The different physico-chemical characteristics of these compounds were also determined. A linear correlation was shown to exist between their redox potentials and spectroscopic data.
