Garrido, E. M.; Lima, J. L. F. C.; Delerue-Matos, C.; Borges, F.; Silva, A. M. S.; Piedade, J. A. P.; Brett, A. M. OliveiraElectrochemical oxidation of propanil in deuterated solutions was studied by cyclic, differential pulse, and square wave voltammetry using a glassy carbon microelectrode. The oxidation of propanil in deuterated acid solutions occurs at the nitrogen atom of the amide at a potential of +1.15 V vs Ag/AgCl. It was also found that, under the experimental conditions used, protonation at the oxygen atom of propanil oc...
Electrochemical oxidation of propanil and related N-substituted amides
Garrido, E. M.; Lima, J. L. F. C.; Delerue-Matos, C.; Borges, F.; Silva, A. M. S.; Brett, A. M. OliveiraThe electrochemical behaviour of propanil and related N-substituted amides (acetanilide and N,N-diphenylacetamide) was studied by cyclic and square wave voltammetry using a glassy carbon electrode. Propanil has been found to have chemical stability under the established analytical conditions and showed an oxidation peak at +1.27 V versus Ag/AgCl at pH 7.5. N,N-diphenylacetamide has a higher oxidation potential ...
Electrochemical studies and square wave adsorptive stripping voltammetry of the...
Silva, A. M. S. Roque da; Lima, J. C.; Teles, M. T. Oliva; Brett, A. M. OliveiraThe electrochemical reduction of the antidepressant drug fluoxetine was investigated by cyclic, linear sweep, differential pulse and square wave voltammetry using a hanging mercury drop electrode in alkaline buffer solution in water and in a water/acetonitrile mixed solvent. Cyclic voltammograms in aqueous solution showed very strong adsorption of fluoxetine on the electrode with formation of a compact film. Th...
