Kinetik und Mechanismus der durch Osmiumtetroxid katalysierten Oxidation von Cyclohexanol und Methylcyclohexanol durch alkalische Hexacyanoferrat(III)-ionen

Kinetics of the OsO₄ catalysed oxidation of the above mentioned cyclic alcohols by hexacyanoferrate(III) in alkaline medium has been studied. The effect of variation of the concentration of osmium tetroxide on the reaction rate shows the direct dependence. The first order kinetics observed at lower concentration of the organic substrates tends towards zero order at higher concentrations. Similarly zero order kinetics was also observed with respect to hexacyanoferrate(III). The order with respect to hydroxide ion is unity at its lower concentrations and changing towards lower order at higher concentrations. On the basis of these results a probable reaction mechanism has been set out and the oxidation products have been confirmed.
