Sažetak

Electrochemical reduction of the –N=N– moiety of sydnone derivatives, like 3-phenyl sydnone, tolyl sydnone and anisyl sydnone, was studied using cyclic voltammetry at a glassy carbon electrode. In acid medium, the above compounds were found to show irreversible electrochemical charge transfer in the pH range studied. Electrochemical studies of these sydnones were carried out in partially aqueous media containing organic co-solvents such as acetonitrile, dimethylformamide, methanol and dimethylsulphoxide. Physical parameters such as the charge transfer coefficient and diffusion coefficient, as well as the effects of variation of the electroactive species concentration, sweep rate, organic solvents, and pH on peak parameters were studied. The reduced products were characterized by IR, NMR and mass spectral studies. The
effect of surfactants on the electrochemical reduction of 3-phenyl sydnone was studied using cationic, anionic and non-ionic surfactants.
