In the present investigation, we have conducted cyclic voltammetry and controlled-potential electrolysis studies of 2-iodo-N-phenylacetamide and 2-bromo-N-phenylacetamide at a carbon cathode to understand further the electrochemical behavior of 2-halo-N-phenylacetamides. Reduction of 2-bromo-N-phenylacetamide and 2-iodo-N-phenylacetamide in dimethylformamide (DMF) containing 0.05 M tetramethylammonium tetrafluoroborate (TMABF4) results in cyclic voltammetry peaks at –0.9 and –1.4 V (bromo) and –0.6 and –1.1 V (iodo) vs. a Cd(Hg) reference electrode. Analysis of the products resulting from controlled-potential electrolyses of both analytes by means of gas chromatography–mass spectrometry (GC–MS) indicates the presence of dehalogenated species as the primary products.
