Spectrophotometric changes accompanying the electrosynthesis of 6-NAC-THMA 5. (spectra a-e): electrochemical oxidation of THMA(1 mM), at a platinum anode (E = + 1.0 V versus Ag/AgCl), in deaerated 0.2 M HCl aqueous solution: (a) 0 (before electrolysis), (b) 0.5, (c) 1.0, (d) 1.5, (e) 2.0 mol of electrons. (spectra f–i): evolution after addition of 2 equiv of N-acetylcysteine to the two electrons-oxidized solution: (f) 10 min after addition, (g) 20 min, (h), 40 min, (i) 50 min (end of the process). Cell thickness is 0.1 cm.
