      The ruthenium(III)-catalysed ferricyanide oxidation of aromatic aldehydes in aqueous alkaline medium follows a zero order kinetics with respect to ferricyanide. The order with respect to Ru(III) is unity. The variation of substrate concentration follows Michaelis-Menton type of kinetics. The dependence on alkali is fractional below 0.05 M and tends to be independent above 0.05 M. The reaction proceeds through the reversible complexation between Ru(III) and the hydrated aldehyde, which decomposes in a rate determining step, giving the products. The structure reactivity relationship has been analysed in the light of Hammett’s plot.
