Abstract

The osmium tetroxide catalysed reactions of alkaline hexacyanoferrate. (III) with methyl digol and ethyl digol were investigated kinetically. The reactions are zero order in hexajanoferrate (III) and of first order in substrate and osmium tetroxide concentrations. With an increase in [math] the rate increased and the reaction showed positive intercept at Y-axis. An inner-sphere mechanism involving complex formation, which then disproportionates to form the products, is suggested.
