✦ Synopsis

The kinetics of the oxidation of cyclopentanol, cyclohexanol, 2-methylcyclohexanol, and cycloheptanol by hexacyanoferrate(II1) ions in mild alkaline medium has been studied in the presence of traces of ruthenium(V1) = lO-?M at constant ionic strength (0.26M). The results suggest that the oxidation of the studied cyclic alcohols proceeds via the formation of a complex between Ru(VI) and the substrate which slowly decomposes, giving the reduced form of ruthenium which was reoxidized to Ru(V1) in a fast step by alkaline hexacyanoferrate(II1) ions. The product study shows the production of the corresponding ketone.
