✦ Synopsis

The rate constants for the protonation of "free" (that is, solvated) superoxide ions by water and ethanol are equal to 0.5-3.5 X lO-~M-l.s-' in DMF and AN at 20'. It has been found that the protonation rates for the ion pairs of 0; with the BudN+ cation are much slower than those for "free" 0,. It is suggested that the effects of aprotic solvents on the protonation rates of 0; are mainly due to the fact that the proton donors form solvated complexes of different stability in these solvents.

## Abstract Absorption spectra of the superoxide ion have been studied in dimethylformamide (DMF) and acetonitrile (AN). It was found that the superoxide ion existed in equilibrium with an ion pair in AN (__K__~eq~ = 20__M__^−1^, Bu~4~N^+^ is the cation) and as “free” (solvated) ion in DMF. The add

The reaction proceeds via the formation of chlorite ion, which in turn reacts with additional iron(II) to produce the observed products. T
