Sažetak

The electrochemical reduction of 2-(2-thiazolylazo)-p-cresol has been studied in phosphate buffers of different pH at a pyrolytic graphite electrode. The reduction of the dye occurred in a single well-defined 4e, 4H+ step and the electrode reaction was found as ECE. The reduction products were separated and characterized by m.p., 1H-NMR and mass spectra. The hydrazo intermediate was found to be unstable and undergoes further reaction, the rate of which obeys the equation rate = r° + k}j [H+] + &QH [OH-].
