Proton-Induced Disproportionation of Superoxide Ion in Aprotic Media

The proton-induced disproportionation of superoxide ion (O2-) in dimethylformamide and in acetonitrile has been studied by stopped-flow spectrophotometry, cyclic voltammetry, and controlled-potential voltammetry at a rotating-disk electrode.For strongly acidic substrates (HClO4, HCl, and NH4ClO4) the disproportionation reaction is second order with respect to O2-, but too rapid to measure accurately, k > 107 M-1 s-1.With less protic substrates (ascorbic acid, phenols, catechols, alcohols, and water) the rate of disproportionation is first order with respect to O2- and with respect to substrate; proton transfer is the rate-limiting step.In dimethylformamide the second-order rate constants range from k = 2x104 M-1 s-1 for ascorbic acid to k = 1x10-3 for water.On the basis of the kinetic data, a self-consistent mechanism for superoxide disproportionation by acidic substrates in nonaqueous solvents is proposed.
