Summary

Kinetic investigations on the RuO4-catalysed oxidation of cyclopentanol (Cypol) and cyclohexanol (Cyhol) in alkaline KBrO3 in the presence of Hg(OAc)2 which acts as a bromide ion scavenger have been made in the 30°–45°C range. The reaction exhibits zero order kinetics in OH and is first order with respect to BrO3, substrate and RuO4. The influence of Hg(OAc)2 and ionic strength is insignificant. A transient complex, formed between HRuO5 (the active species of RuO4) and the cyclic alcohol, reacts with BrO3 in a slow, rate determining step to give the products; the catalyst is regenerated.
