Abstract:	The oxidation reactions of Fe(CN)5L3- (L = 4-ampy, py, dpa) complexes by S2O82- were catalyzed upon the addition of a trace amount of Ru(NH3)5L′2+(L′ = pz, py or dcb) complex, and the reaction becomes zero-order in Fe(II). The reaction time is ∼102 fold faster than the simple Fe(CN)5L3-S2O82- system. The mechanism of this Ru(II) catalyzed redox reaction is proposed as Ru(NH3)5L′2+ + 1/2 S2O82- → Ru(NH3)5L′3+ + SO42- Ru(NH3)5L′3+ + Fe(CN)5L3- ? Ru(NH3)5L′2+ + Fe(CN)5L2-.
