Kinetics of peroxodisulphate oxidations in t-butyl alcohol–water solvent mixtures

Abstract

Kinetics of reaction between peroxodisulphate and iodide, hexacyanoferrate(II), and a series of substituted tris-(1,10-phenanthroline)- and tris-(2,2′-bipyridyl)-iron(II) complexes have been investigated in aqueous t-butyl alcohol. The iron(II) complexes react by parallel oxidation and aquation, the relative importance of these two paths depending on solvent composition and ligand substituent. The variation of rates of oxidation with solvent composition does not reflect the effect of the t-butyl alcohol on the structure of the water in the way that has been observed for aquation of several complexes.
