Self-Protonation Reaction of Simple Aromatic Carboxylic Acids During Voltammetric Reduction in Dimethyl Sulfoxide

The electrochemical behavior of three simple aromatic carboxylic acids, benzoic acid (PhCOOH), 1-naphthoic acid (NphCOOH) and 9-anthroic acid (AnCOOH) has been studied in dimethyl sulfoxide.The results of cyclic voltammetry and derivative cyclic voltammetry (DCV) suggest that the initial electrode process was formation of the corresponding anion radical, which for NphCOOH and AnCOOH, and possibly also for PhCOOH, was protonated by the substrate in a so-called self-protonation step followed by further reaction of ArHCOOH(radical).ArCOOH(anion radical) + ArCOOH ArHCOOH(radical) + ArCOO- (i) The coulometric n-values determined by constant current coulometry were observed to be close to unity in agreement with the stoichiometry of the overall reaction, eqn. (ii), where ArH2COO- is the base corresponding to the dihydrogenated product, ArH2COOH.The latter was isolated in good yield together with ArCOOH after preparative electrolyses of NphCOOH and AnCOOH. 2 ArCOOH + 2 e- ArH2COO- + ArCOO- (ii) The kinetics of reaction (i) were studied by DCV for NphCOOH and AnCOOH.The rate constants, ki, obtained were 4.7 * 10E6 M-1 s-1 (NphCOOH) and 2.9 * 10E6 M-1 s-1 (AnCOOH), respectively.Definitive conclusions regarding PhCOOH could not be drawn.The voltammetric reduction stayed chemically irreversible at voltage sweep rates up to 1000 V s-1 and only polymeric products were isolated after preparative electrolysis.
