Abstract Ruthenium(III)-edta reacts with the 2-mercaptonicotinic ligand in aqueous solution yielding a red product (λmax = 530 nm) coordinated at the S atom. This species undergoes deprotanation with an apparent pKa = 3.80, generating a blue complex in which the ligand is (S, N)-bidentate. In the presence of two times excess of ruthenium(III)-edta a binuclear species is formed, involving two bidentate
Reported is the first example of a ruthenium(III)-complex, RuIII(EDTA) (EDTA4− = ethylenediaminetetraacetate), that mediates O-atom transfer from nitrite to the biological thiols cysteine and glutathione, leading to the formation of [RuIII(EDTA)(NO+)]0. However, at pH below 5.0, the coordinated nitrite ion in the [RuIII(EDTA)(NO2)]2− complex undergoes proton-assisted decomposition, resulting in the formation of a [RuIII(EDTA)(NO+)]0 species.

aminetetraacetate) catalyzes the oxidation of thiourea (TU) by peroxomonosulfate ion (HSO5−). The kinetics of the catalytic oxidation process was studied by using stopped-flow and rapid-scan spectrophotometry as a function of [RuIII(edta)(H2O)−], [HSO5−] and [TU] at a constant pH of 6.2 (phosphate buffer) and temperature of 25 °C. Spectral and kinetic data are suggestive of a catalytic pathway involving

= 2. The reaction of AMD6245 and AMD6221 with nitric oxide is investigated using EPR spectroscopy and stopped flow kinetics. Upon reaction with NO, a linear, diamagnetic [RuNO](6) complex is formed. The substitutionreaction of AMD6245 with NO proceeds with a second-order rate constant of 2.24 x 10(7) M(-1) s(-1) at 7.3 degrees C (pH = 7.4; 50 mM phosphate buffer). The substitutionreaction of AMD6221
