Kinetics and Mechanism of the Oxidation of Iodide by trans-Dioxoruthenium(VI)

The kinetics of reduction of trans-(2+) (tmc = 1,4,8,11-tetramethyl-1,4,8,11-tetraazacyclotetradecane) by iodide has been studied in aqueous acidic solution.The reaction has the following stoichiometry: trans-(2+) + 3I(1-) + 2H(1+) --> trans-(2+) + I3(1-).The rate low is -d/dt = (ka + kb) with ka = 0.041 +/- 0.013 dm3 mol-1 s-1 and kb = 18.5 +/- 0.2 dm6 mol-2 s-2 at 25.0 deg C and 0.1 mol dm-3 ionic strength.For ka ΔH(excit.) = 42.9 +/- 9.4 kJ mol-1 and ΔS(excit.) = -131 +/- 40 J K-1 mol-1, while for kb, ΔH(excit.) = 36.9 +/- 2.9 kJ mol-1 and ΔS(excit.) = -97 +/- 10 J K-1 mol-1.A mechanism involving oxygen-atom transfer from Ru(VI) to iodide is consistent with the data.
