A small library of 17 organoruthenium compounds with the general formula [RuII(fcl)(chel)(L)]n+ (in which fcl=face capping ligand, chel=chelating bidentate ligand, and L=monodentate ligand) were screened for inhibitory activity against cholinesterases and glutathione-S-transferases of human and animal origins. Compounds were selected to include different chelating ligands (i.e., N,N-, N,O-, O,O-, S,O-) and monodentate ligands that can modulate the aquation rate of the metal species. Compounds with a labile ruthenium chloride bond that provided rapid aquation were found to inhibit both sets of enzymes in reversible competitive modes and at pharmaceutically relevant concentrations. When applied at concentrations that completely abolish the activity of human acetylcholinesterase, the lead compound [(eta6-p-cymene)Ru(pyrithionato)Cl] (C1 a) showed no undesirable physiological responses on the neuromuscular system. Finally, C1 a was not cytotoxic against non-transformed cells at pharmaceutically relevant concentrations.

The [3 + 2] cycloaddition reaction of selective azido complexes with the activated alkynes dimethyl and diethyl acetylenedicarboxylates produced the arene triazolato complexes [(eta6-arene)Ru(LL){N3C2(CO2R)2}] [arene = p-iPrC6H4Me, LL = L1, R = Me (13); arene = C6Me6, LL = L1, R = Me (14); arene = C6Me6, LL = acetyl acetone (L2), R = Me (15); arene = C6Me6, LL = L3, R = Me (16); arene = p-iPrC6H4Me, LL = L1, R = Et (17); arene = C6Me6, LL = L1, R = Et (18); arene = C6Me6, LL = L2, R = Et (19); arene = C6Me6, LL = L3, R = Et (20)]. With fumaronitrile the reaction yielded the triazoles [(eta6-arene)Ru(LL)(N3C2HCN)] [arene = p-iPrC6H4Me, LL = L1 (21), arene = C6Me6, LL = L1 (22), arene = C6Me6, LL = L2 (23), arene = C6Me6, LL = L3 (24)].

The chemoselective hydrogenation of acetylacetone to 4-hydroxypentan-2-one over immobilized ruthenium phenanthroline metal complexes in amino functionalized MCM-41 in biphasic aqueous reaction medium was investigated. The catalyst was characterized by XRD, TEM, surface analysis, FT-IR and UV-vis to understand the morphology, complex geometry, and XPS such that the oxidation state of the metal complex inside the MCM-41 framework could be understood. The use of water as a solvent, not only gives high activity and selectivity for hydrogenation of acetylacetone, but also gives a path for an environmentally safer process. The optimizations of ligand, metal to ligand ratio, the choice of solvent and other reaction parameters were studied in detail. The heterogeneous catalytic system gave a higher degree of chemoselectivity (99%) towards 4-hydroxypentan-2-one as compared to homogeneous catalyst when hydrogenation was carried out using water as a solvent. The immobilized ruthenium-phenanthroline complex was easily separated and reused.

The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.246047-72-3, Name is (1,3-Bis(2,4,6-trimethylphenyl)-2-imidazolidinylidene)dichloro(phenylmethylene)(tricyclohexylphosphine)ruthenium, molecular formula is C46H65Cl2N2PRu. In a Article，once mentioned of 246047-72-3, Product Details of 246047-72-3

Ruthenium carbene catalysts are able to catalyze crossed [2+2+2] cyclotrimerizations of alpha,omega-diynes with isocyanates, isothiocyanates, and carbon disulfide. Both aliphatic and aromatic isocyanates can be used to produce fused 2-pyridones, although aliphatic isocyanates were more reactive. Aromatic isocyanates give better results when they bear electron-donating substituents. The reaction of unsymmetrical alpha,omega-diynes gave a product only with the substituent adjacent to the 2-pyridone nitrogen. Isothiocyanates gave thiopyranimines upon reaction with the C-S bond, whereas CS2 reacted efficiently to give a thioxothiopyrane.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Product Details of 246047-72-3, you can also check out more blogs about246047-72-3

A new 18-electron ruthenium complex, where ruthenium catalytic center is coordinated with the N-mesitylimidazole and nitrate ligands, as well as o-isopropoxystyrene moiety, is reported. The synthesis and detailed characterization of the Ru complex, together with density functional theory calculations (DFT), are presented. The complex is air- and moisture-stable, although has weak catalytical activity in the model metathesis reactions. However, its activity increases upon the addition of an aqueous HCl 1 M solution. Activated Ru complex successfully promotes metathesis in organic solvents as well as in water, enabling efficient performance (even up to 100%) of the catalyst under environment-friendly conditions. The activation mechanism of the reported catalyst is supported by time-dependent DFT calculations and ab initio molecular dynamics simulations.

The authors restrict this investigation to Ru/InP and Ru/GaInPAs contacts. The large grain polycrystalline quaternary semiconductor has been chosen because of differences in surface chemistry. Experimental data show that the typical current enhancement upon metallization is found. The increase in catalytic activity is larger for InP. A somewhat lower overall photoactivity is noted for GaInPAs.

Reference of 15746-57-3, Chemistry can be defined as the study of matter and the changes it undergoes. You’ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology.15746-57-3, Name is Cis-Dichlorobis(2,2′-bipyridine)ruthenium(II), molecular formula is C20H16Cl2N4Ru. In a patent, introducing its new discovery.

Catalytically competent Ir, Re, and Ru complexes H2L 1-H2L6 with dicarboxylic acid functionalities were incorporated into a highly stable and porous Zr6O 4(OH)4(bpdc)6 (UiO-67, bpdc = para-biphenyldicarboxylic acid) framework using a mix-and-match synthetic strategy. The matching ligand lengths between bpdc and L1-L 6 ligands allowed the construction of highly crystalline UiO-67 frameworks (metal-organic frameworks (MOFs) 1-6) that were doped with L 1-L6 ligands. MOFs 1-6 were isostructural to the parent UiO-67 framework as shown by powder X-ray diffraction (PXRD) and exhibited high surface areas ranging from 1092 to 1497 m2/g. MOFs 1-6 were stable in air up to 400 C and active catalysts in a range of reactions that are relevant to solar energy utilization. MOFs 1-3 containing [Cp*Ir III(dcppy)Cl] (H2L1), [Cp*Ir III(dcbpy)Cl]Cl (H2L2), and [Ir III(dcppy)2(H2O)2]OTf (H 2L3) (where Cp* is pentamethylcyclopentadienyl, dcppy is 2-phenylpyridine-5,4?-dicarboxylic acid, and dcbpy is 2,2?-bipyridine-5,5?-dicarboxylic acid) were effective water oxidation catalysts (WOCs), with turnover frequencies (TOFs) of up to 4.8 h -1. The [ReI(CO)3(dcbpy)Cl] (H 2L4) derivatized MOF 4 served as an active catalyst for photocatalytic CO2 reduction with a total turnover number (TON) of 10.9, three times higher than that of the homogeneous complex H 2L4. MOFs 5 and 6 contained phosphorescent [Ir III(ppy)2(dcbpy)]Cl (H2L5) and [RuII(bpy)2(dcbpy)]Cl2 (H2L 6) (where ppy is 2-phenylpyridine and bpy is 2,2?-bipyridine) and were used in three photocatalytic organic transformations (aza-Henry reaction, aerobic amine coupling, and aerobic oxidation of thioanisole) with very high activities. The inactivity of the parent UiO-67 framework and the reaction supernatants in catalytic water oxidation, CO2 reduction, and organic transformations indicate both the molecular origin and heterogeneous nature of these catalytic processes. The stability of the doped UiO-67 catalysts under catalytic conditions was also demonstrated by comparing PXRD patterns before and after catalysis. This work illustrates the potential of combining molecular catalysts and MOF structures in developing highly active heterogeneous catalysts for solar energy utilization.

A series of seven dyad molecules have been prepared utilizing a [Ru(tpy)(NN)I]+ type oxidation catalyst (NN = 2,5-di(pyrid-2?- yl) pyrazine (1), 2,5-di-(1?,8?-dinaphthyrid-2?-yl) pyrazine (2), or 4,6-di-(1?,8?-dinaphthyrid-2?-yl) pyrimidine (3). The other bidentate site of the bridging ligand was coordinated with 2,2?-bipyridine (bpy), 1,10-phenanthroline (phen), or a substituted derivative. These dinuclear complexes were characterized by their 1H NMR spectra paying special attention to protons held in the vicinity of the electronegative iodide. In one case, 10a, the complex was also analyzed by single crystal X-ray analysis. The electronic absorption spectra of all the complexes were measured and reported as well as emission properties for the sensitizers. Oxidation and reduction potentials were measured and excited state redox properties were calculated from this data. Turnover numbers, initial rates, and induction periods for oxygen production in the presence of a blue LED light and sodium persulfate as a sacrificial oxidant were measured. Similar experiments were run without irradiation. Dyad performance correlated well with the difference between the excited state reduction potential of the photosensitizer and the ground state oxidation potential of the water oxidation dyad. The most active system was one having 5,6-dibromophen as the auxiliary ligand, and the least active system was the one having 4,4?-dimethylbpy as the auxiliary ligand.

The synthesis of N,N-dimethylformamide from carbon dioxide, hydrogen and dimethylamine has been studied in an autoclave using a sol-gel derived heterogeneous catalyst made of RuCl2{PPh2(CH2)2Si(OEt)3}3 and Si(OEt)4 in a ratio of 1:50. The effect of the reaction variables on the activity and selectivity of the hybrid gel was examined by varying the initial concentrations of the catalyst and dimethylamine, the partial pressures of hydrogen and carbon dioxide, the temperature and the stirring frequency. Parametric investigations revealed that the measured reaction rates are not disguised by mass transfer phenomena under the conditions applied. The suitable temperature range of the reaction is between 370 and 400 K, with the upper temperature limit given by the thermal stability of the catalyst. Hydrogen appeared to be the limiting reactant since it significantly influenced the reaction rate. In contrast, the carbon dioxide partial pressure in the range 3-18 MPa and the dimethylamine concentration had only a negligible effect on the turnover frequency, indicating a zeroth order dependence. High concentrations of hydrogen and carbon dioxide in the liquid dimethylamine phase afford high concentrations of all reactants at the catalytic centres in an ideal reaction design.
