Abstract

The kinetics of the reaction of the superoxide ion with ethyl acetate have been studied in DMF, AN, and their mixtures. It was shown that the rate constants depend on the ethyl acetate concentration, which indicates the formation of an intermediate in this process. Equilibrium constants for the process of the intermediate formation and the rate constants for its decay have been determined. It is concluded that aprotic solvents affect mainly the stage of the intermediate decay in this reaction.

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 i

## 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 of copper metal with various substituted benzyl bromides in dimethylformamide has been studied and the kinetic and thermodynamic parameters of the reaction have been obtained. Hammett plots of log(k/k • ) vs the substituent constant σ gave good correlations (ρ = 0.24, S ρ = 0.03, r = 0.

The reaction has been studied spectrophotometrically monitoring the absorbance in the wavelength range. The spectra of the reactants, intermediates, and prod-240-400 nm ucts in this system are overlapping; thus special programs [1,2] have been used (and tested) to unravel the kinetics and mechanism
