Photoanation reactions of hexa(dimethyl sulphoxide)chromium(III) ion by azide and thioycanate: evidence for associative reaction

Abstract

Quantum yields for the anation of [Cr(dmso)₆]³⁺(dmso = dimethyl sulphoxide) by N₃^– are distinctly larger than those for anation by SCN^– at all concentrations, including those where limits imposed by ion association are approached; in conjunction with a measurement on the solvent exchange process, these results are taken to support an associative mechanism.
