The complex 2+ (terpy = 2,2':6',2''-terpyridine, tmen = N,N,N',N'-tetramethylethylenediamine) and its corresponding oxo complex have been prepared.Their spectral properties and redox properties in aqueos solution were investigated.Evidence for two one-electron redox processes has been obtained for the Ru^IV-Ru^III and Ru^III-Ru^II couples.The reaction of the new ruthenium(IV) oxo species with olefins have been found to proceed with second-order kinetics, rate = k₂IV> where k₂ = (3.3 +/- 0.3) x 10^-3 and (2.0 +/- 0.2) x 10^-2 dm³mol^-1s^-1 at 25 deg C for norbornene and styrene respectively
