Ruthenium nitrosyl nitrate has been used as a precursor to prepare Cl-free RuOx with the scope of investigating the role of the residual chlorine present in RuOx obtained by thermal decomposition of RuCl3. Ti-supported layers were prepared in the temperature range 270-500C. Surface and electrocatalytic properties have been investigated by means of voltammetric curves, Tafel plots, reaction order, and activation energy determinations. The results have shown that Cl-free RuOx does not behave differently from RuOx containing Cl, although both the range of temperature where the stable oxide is formed and the surface morphology depend on the nature of the precursor.

The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.301224-40-8, Name is (1,3-Dimesitylimidazolidin-2-ylidene)(2-isopropoxybenzylidene)ruthenium(VI) chloride, molecular formula is C31H38Cl2N2ORu.

Simple models of the spiroimine core of (-)-gymnodimine A have been synthesized in racemic and optically active forms. The quaternary carbon of the racemic spiroimines was created by Michael addition of a beta-ketoester to acrolein, whereas the asymmetric allylic alkylation of the same beta-ketoester was used to access the spiroimines in an enantioselective fashion. Both racemic and enantio-enriched mixtures were tested for their biological activities on Xenopus oocytes either expressing (human alpha4beta2) or having incorporated (Torpedo alpha12betagammadelta) nicotinic acetylcholine receptors (nAChRs). These spiroimine analogs of (-)-gymnodimine A inhibited acetylcholine-evoked nicotinic currents, but were less active than the phycotoxin. Our results reveal that the 6,6-spiroimine moiety is important for the blockade of nAChRs and support the hypothesis that it is one of the pharmacophores of this group of toxins.

A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 10049-08-8, Name is Ruthenium(III) chloride, molecular formula is Cl3Ru.

Cyclohexane, cyclohexene, and alpha-pinene react with dioxygen in the liquid phase in the presence of catalysts based on platinum, heteropoly compounds (HPCs), metal-containing HPCs, and combinations of these components. In cyclohexane and alpha-pinene oxidations occurring by an autooxidation mechanism at 160-170 and 80- 90C, respectively, the catalysts serve to control free-radical processes. The simultaneous action of a Ru-containing phosphotungstate as a hydroperoxide decomposition catalyst and of a V-containing phosphotungstate as a scavenger of hydroxyl and alkoxyl radicals increases the cyclohexanol + cyclohexanone selectivity of cyclohexane oxidation without yielding a hydroperoxide. A Pt/C catalyst affords an increase in alpha-pinene conversion in a fixed time. In combination with ammonia or tetrahexylammonium chloride admixtures, it retards side reactions and raises the yield of verbenol and verbenone, which are the most valuable products. During cyclohexane, cyclohexene, and alpha-pinene oxidation with an O2-H2 mixture at room temperature, no free-radical chain reaction develops in the Pt-HPC system and reactive intermediates form and interact, involving the HPC, with hydrocarbons on the surface of the platinum catalyst. Analysis of reactivity and of the composition of substrate oxidation products suggests a mechanism for the conjugate oxidation of hydrocarbons in systems with various HPCs. In this mechanism, HPC composition determines, to a large extent, the nature of reactive intermediates, which may be peroxides or radicals bound to platinum or HPC. The properties of catalytic systems in oxidation with O 2-H2 mixtures can be controlled by selecting an appropriate HPC as the modifying component.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.Formula: Cl3Ru, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 10049-08-8, in my other articles.

Biophysical interaction of amphiphilic fluorescent surfactant?ruthenium(II) complexes and its precursor ruthenium(II) complexes with drug carrying proteins such as bovine and human serum albumins (BSA and HSA) have been studied through the UV-visible absorption, fluorescence and circular dichroism spectroscopic techniques to correlate the impact of head and tail groups of the metallosurfactants towards the designing of metallodrugs for the biomedical applications. The obtained results showed that both precursor? and surfactant?ruthenium(II) complexes interact with BSA/HSA via ground state protein?complex formation and their quenching follows the static mechanism. The extent of protein quenching and binding parameters resulted that the surfactant?ruthenium(II) complexes effectively interact with protein compared to their precursor?ruthenium(II) complexes, and also those interaction have greatly influenced by the change in the head group size compared to change in the tail group length. Interestingly on increasing the temperature, the protein?complex binding strength was decreased for the precursor?ruthenium(II) complexes, those increased for the surfactant?ruthenium(II) complexes, probably due to the respective involvement of electrostatic and hydrophobic interactions as supported by the thermodynamics of protein?complex interaction. Moreover, the results from UV?visible, synchronous and circular dichroism studies confirmed the occurrence of conformational and micro environmental changes in BSA/HSA upon binding with these complexes. It is also noted that HSA has more binding affinity with surfactant?ruthenium(II) complexes compared to BSA. The free radical scavenging ability against DPPH, ABTS, NO and superoxide free radical assays suggested that surfactant?ruthenium(II) complexes have better free radical scavenging ability compared to precursor?ruthenium(II) complexes.

Parahydrogen (p-H2) induced polarization (PHIP) NMR spectroscopy showed that [CpXRu] complexes with greatly different electronic properties invariably engage propargyl alcohol derivatives into gem-hydrogenation with formation of pianostool ruthenium carbenes; in so doing, less electron rich CpX rings lower the barriers, stabilize the resulting complexes and hence provide opportunities for harnessing genuine carbene reactivity. The chemical character of the resulting ruthenium complexes was studied by DFT-assisted analysis of the chemical shift tensors determined by solid-state 13C NMR spectroscopy. The combined experimental and computational data draw the portrait of a family of ruthenium carbenes that amalgamate purely electrophilic behavior with characteristics more befitting metathesis-active Grubbs-type catalysts.
