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. In a Conference Paper，once mentioned of 10049-08-8, SDS of cas: 10049-08-8

The electrochemical oxidation of CH3OH at nanometer-scale PtRu catalyst materials is reported. Comparisons are made between the properties of a Johnson Matthey (JM) PtRu black sample (50 at.% Ru (XRu ? 0.5)) and PtRu particles (2-6 nm, nominally XRu ? 0.5) prepared by sonication under anhydrous conditions. Cyclic voltammetry and in situ infrared spectroscopy measurements show the catalysts are active for the oxidation, of 0.5 M CH3OH in 0.1 M HClO4 at temperatures between ambient and 70C. The sonochemically prepared PtRu sample displayed properties characteristic of bulk PtRu alloys with XRu ? 0.5. Evidence for phase separation of Pt and Ru was observed in CO stripping voltammetry from the JM catalyst adsorbed at low metal loadings (20 mug/cm2) on bulk Au electrodes. Per gram of catalyst, the JM material was more active toward CO 2 formation and displayed greater resistance to poisoning by adsorbed CO than the sonochemically prepared material during ambient temperature oxidation of 0.5 M CH3OH in 0.1 M HClO4.

The molecular structures of the complexes (1)-(4), determined by single-crystal X-ray analysis of the hexafluorophospate salts, are also reported. In (5)(PF6)2-(7)(PF6) 2, the nucleobase 9MeG binds to ruthenium through N7. Based on 1H NMR spectroscopy, a strong shielding effect between the aromatic ring system of the quinoxaline or benzo[g]quinoxaline moiety of the ligands pqx and pbqx and the H8 of 9MeG was observed. The complexes (1)-(4) are highly cytotoxic as chloride salts, against various cancer cell lines, with their IC50 values observed at less than 1 muMu.

cis-Dichloro-bis(2-(2-pyridyl)-4-carbonylmethylquinoline)ruthenium (II) complex was synthesized and its structure, electrochemical, electronic absorption and emission properties were determined. A derivative Ru(II) complex with radical initiating sites was employed in the atom transfer radical polymerization (ATRP) of functional N-(omega?-alkylcarbazoly) methacrylates to provide linear metallopolymers with the metal chromophores at one termini of the polymer chain. These polymers were characterized by gel permeation chromatography in combination with low-angle laser light-scattering, UV-Vis and emission spectroscopy to verify the covalent attachment of the metal chromophores to the polymer chain. The polymers thermal transitions and thermal stabilities were also investigated by differential scanning calorimetry and thermogravimetric analysis.

This family of olefin metathesis catalysts was fully characterized (1H, 13C and 31P NMR spectroscopy and elemental analysis) and provided excellent activity in the ring-opening metathesis polymerization of 1,5-cyclooctadiene and the ring-closing metathesis of diethyl diallylmalonate. Comparison with the corresponding benzylidene-containing catalysts, 1a,c and 8b, established the decisive role of the carbene ligand on the procedure of the reaction and led to the observation of an unusual catalytic phenomenon, here called “self-inhibition”.

An efficient and original stereocontrolled transannular rearrangement starting from activated 2,5-diketopiperazines has been developed, an opportunity for the medicinal chemistry field, which requests access to novel biological scaffolds. This powerful ring contraction, which can be related to a stereoselective aza-version of the Chan rearrangement, allows for example the one-step synthesis of various tetramic acids, access to 2-disubstituted statins, or the synthesis of relevant lactam-constrained dipeptide mimetics using a TRAL-RCM sequence.

(Chemical Equation Presented) Oxidation without organics: A tetraruthenium polyoxometalate (see picture; Ru blue, O red, Si yellow, W black) catalyzes the rapid oxidation of H2O to O2 in water at ambient temperature, and shows considerable stability under turnover conditions. The complex was characterized by several methods, including X-ray crystallography and cyclic voltammetry.

In a Article，once mentioned of 37366-09-9, Application In Synthesis of Dichloro(benzene)ruthenium(II) dimer

The bis(oxazoline) ligand, 2,2-bis[4(R)-phenyl-1,3-oxazolon-2-yl]propane (bpop), was introduced to the eta6-benzeneruthenium(II) moiety on treatment with [Ru(eta6-C6H6)Cl2]2 to give [Ru(eta6-C6H6) (bpop)Cl]+. Aquo and amine complexes [Ru(eta6-C6H6) (bpop) (L)]2+ (L=H2O (1), NH2R; R=H (2), Me (3), and n-Bu (4)) were prepared by treating the chloride complex with AgBF4 in the presence of L. X-ray structure determinations of 1 and 3 were carried out. Both complexes possessed a three-leg piano stool structure with the N or O donors located at the three corners of a pseudo octahedron. The aquo complex 1 exhibited a dynamic NMR feature in which two magnetically non-equivalent oxazoline parts observed at lower temperatures were interchanged with each other at higher temperatures. This observation was ascribed to the formation of a C2-symmetric 16-electron intermediate via Ru-OH2 cleavage, which is slower in acetone than in dichloromethane owing to more effective solvation by acetone around hydrogens of the coordinated water molecule. The two diastereotopic N-hydrogens of 4 underwent deuterium exchange with CD3OD with greatly different rates from each other owing to different energy of NH…O(D)(CD3) interaction. Carboxylate and sulfonate ions (A-) formed second sphere complexes with 4 by means of NH…A- hydrogen bonding, as evidenced by continuous shift of NH2 resonances with increasing amounts of the anions added.

New Ruthenium complexes I, II and III were synthesized using 5-chlorothiophene-2-carboxylic acid (5TPC), as ligand and the complexes were characterized by elemental analysis, FT-IR, 1H, 13C NMR, and mass spectroscopic techniques. Photophysical and electrochemical studies were carried out and the structures of the synthesized complex were optimized using density functional theory (DFT). The molecular geometry, the highest occupied molecular orbital (HOMO), the lowest unoccupied molecular orbital (LUMO) energies and Mulliken atomic charges of the molecules are determined at the B3LYP method and standard 6-311++G (d,p) basis set starting from optimized geometry. They possess excellent stabilities and their thermal decomposition temperatures are 185 C, 180 C and 200 C respectively, indicating that the metal complexes are suitable for the fabrication processes of optoelectronic devices.
