N2  - The oxidation of cyclohexanol by ferricyanide in alkaline aqueous solution is catalysed by micromolar concentrations of K3RuCl6. The rate law at 25.0ºC in pH 11.9 phosphate buffer containing 0.50 M NaCl is -d[FeIII]/dt = [Ru](2klk2[alcohol][FeIII])/(2kl[alcohol] + k2[FeIII])  with kl 12 ± 2 mol-1 1. s-1 and k2 (2.5 ± 0.2) &#215; 102 mol-1 1. s-1. A deuterium isotope effect of about 4 is observed when (D12)cyclohexanol is used. A mechanism consistent with these observations involves reduction of the RuIII catalyst by hydride transfer from the alcohol followed by reoxidation by ferricyanide to the original RulIII state.
