Kinetic studies on the oxidation of oxalate and malonate by bis(μ-oxo)manganese(III, IV)-cyclam complex

Kinetics and mechanism of the redox interaction of bis(μ-oxo)manganese(III,IV)-cyclam complex with oxalate and malonate in the range of pH 3.6-6.0 (acetate buffer) at 25° have been reported. Analysis of kinetic data reveals the formation of a hydrogen bonded adduct prior to the electron transfer. Both protonated and deprotonated forms of the manganese species take part in reaction revealed through pH-rate profiles.
