The heteronuclear complex [(Me2PhP)3Cl2Re?N-RuCl2(C 6H6)] (1) is obtained by the reaction of [ReNCl2(PMe2Ph)3] with [RuCl2(C6H6)]2 in C6H5CN in form of red crystals with the composition 1·C6H5CN crystallizing in the monoclinic space group P21/c with a =1149.77(8), b = 3085.9(3), c = 1172.1(1) pm, beta = 104.766(9) and Z = 4. In the dinuclear complex the complex fragment [RuCl2(C6H6)] is connected by an asymmetric nitrido bridge with the nitrido complex [ReNCl2(PMe2Ph)3]. The nitrido bridge is characterised by a bond angle Re-N-Ru of 170.6(3) and distances Re-N = 170.2(5) and Ru-N = 199.0(5) pm. The reaction of [ReNCl2(PMe2Ph)3] with [RhCl(COD)]2 in benzo-nitrile yields orange crystals of [(Me2PhP)3Cl2Re?N-RhCl(COD)] (2) with the space group P21/c and a = 1522.3(2), b = 1274.85(4), c = 1921.2(2) pm, beta = 106.759(7) and Z = 4. The monovalent Rh atom exhibits a square planar coordination with the two pi-bonds of the cycloocta-1,5-diene occupying cis positions. The distances in the almost linear nitrido bridge (Re-N-Rh = 174.8(4)) are Re-N = 172.2(6) pm and Rh-N = 195.6(6) pm.

Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments.Introducing a new discovery about 10049-08-8, Name is Ruthenium(III) chloride, Product Details of 10049-08-8.

1H NMR spectroscopy and viscosity measurements have been used to study the oligonucleotide binding of the Delta-and Lambda-enantiomers of the metal complex [Ru(dmphen)2dpq]2+ (dmphen = 2,9-dimethyl-1,10-phenanthroline and dpq = dipyrido[3,2-f:2?,3?-h]quinoxaline). The addition of either enantiomer to d(GTCGAC)2 induced large upfield shifts and significant broadening for the hexanucleotide imino and metal complex dpq resonances. These data coupled with the observed increase in the melting transition midpoint of the hexanucleotide duplex upon addition of either enantiomer suggests that both Delta- and Lambda-[Ru(dmphen)2dpq]2+ bind by intercalation. A significant number of metal complex to hexanucleotide NOE contacts were observed in NOESY spectra of d(GTCGAC)2 with added Delta- or Lambda-[Ru(dmphen)2dpq]2+. The observed intermolecular NOEs were consistent with both enantiomers intercalating between the G4A5 bases of one strand and the T2C3 bases of the complementary strand. Intermolecular NOEs from the dmphen protons were only observed to protons located in the hexanucleotide minor groove. Alternatively, NOE contacts from the dpq protons were observed to both major and minor groove protons. The NOE data suggest that the dpq ligand of the Delta-enantiomer intercalates deeply into the hexanucleotide base stack while the Lambda-enantiomer can only partially intercalate. Viscosity measurements were consistent with the proposed intercalation binding models. The addition of the Delta-enantiomer increased the relative viscosity of the DNA solution, while a decrease in the relative viscosity of the DNA was observed upon addition of the Lambda-metal complex. These results confirm our proposal that octahedral metallointercalators can intercalate from the minor groove. In addition, the results demonstrate that the left-handed enantiomer of [Ru(dmphen)2dpq]2+ prefers to intercalate from the narrow minor groove despite only being able to partially insert a polycyclic aromatic ligand into the DNA base stack.

Chiral porous zirconium phosphonates containing metal complex moieties are provided, synthesized via a molecular building block approach, and characterized by a variety of techniques including TGA, adsorption isotherms, XRD, SEM, IR, and microanalysis. These hybrid solids may be used for enantioselective heterogeneous asymmetric hydrogenation of aromatic ketones with remarkably high e.e. values of up to 99.2%. Similarly prepared chiral porous solids may be used for asymmetric hydrogenation of beta-keto esters with e.e.’s of up to 95%. The solid catalysts can also be easily recycled and reused multiple times without the loss of activity and enantioselectivity. Ready tunability of such a molecular building block approach allows the optimization of these hybrid materials to provide practically useful heterogeneous asymmetric catalysts.

Electric Literature of 15746-57-3, Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. 15746-57-3, Name is Cis-Dichlorobis(2,2′-bipyridine)ruthenium(II), molecular formula is C20H16Cl2N4Ru. In a Article，once mentioned of 15746-57-3

We have used a novel microwave-assisted method developed in our laboratories to synthesize a series of ruthenium-thiosemicarbazone complexes. The new thiosemicarbazone ligands are derived from benzo[d][1,3]dioxole-5- carbaldehyde (piperonal) and the complexes are formulated as [(diimine) 2Ru(TSC)](PF6)2 (where the TSC is the bidentate thiosemicarbazone ligand). The diimine in the complexes is either 2,2?-bipyridine or 1,10-phenanthroline. The complexes have been characterized by spectroscopic means (NMR, IR and UV-Vis) as well as by elemental analysis. We have studied the biophysical characteristics of the complexes by investigating their anti-oxidant ability as well as their ability to disrupt the function of the human topoisomerase II enzyme. The complexes are moderately strong binders of DNA with binding constants of 104 M -1. They are also strong binders of human serum albumin having binding constants on the order of 104 M-1. The complexes show good in vitro anticancer activity against human colon cancer cells, Caco-2 and HCT-116 and indeed show some cytotoxic selectivity for cancer cells. The IC50 values range from 7 to 159 muM (after 72 h drug incubation). They also have antibacterial activity against Gram-positive strains of pathogenic bacteria with IC50 values as low as 10 muM; little activity was seen against Gram-negative strains. It has been established that all the compounds are catalytic inhibitors of human topoisomerase II.

This paper describes a new technique entitled scanning differential electrochemical mass spectrometry (SDEMS) that combines a quadrupole mass spectrometer with a membrane-covered capillary inlet and a high resolution positioning system that is designed to perform spatial mapping in solution near an electrode interface. Potential applications of this technique include the local characterization of anode catalysts for fuel cells as well as a range of analytical measurements and combinatorial screening studies. The capabilities of this technique are demonstrated by monitoring product evolution in several model electrocatalytic reactions, including the hydrogen evolution reaction, carbon monoxide oxidation, and the direct oxidation of methanol on platinum and platinum-ruthenium electrodes. The inlet of the SDEMS is based upon a small diameter capillary tube to which a nanoporous, hydrophobic membrane is attached. The capillary inlet is positioned near a substrate electrode using a three-dimensional positioning system. The effect of capillary substrate separation and substrate current on the sensitivity and time response of mass spectrometer’s ion current are illustrated during hydrogen evolution at a platinum substrate. The sensitivity is demonstrated further by detection of carbon dioxide evolution during the oxidation of a monolayer of carbon monoxide adsorbed on platinum. The ability to address more complex reactions involving complete and partial oxidation products is illustrated with methanol oxidation. In order to demonstrate the ability of this technique to perform spatial mapping, an eight-element band electrode was interrogated for hydrogen evolution and methanol oxidation. Detection of ion currents associated with complete and partial oxidation products of methanol on a set of platinum-ruthenium band electrodes illustrates the ability of this method to spatially discriminate between various reactive sites on a surface, which has potential utility in analytical characterization as well as application as a screening tool in combinatorial catalysis studies.

We report on the synthesis of novel water-soluble [(arene)Ru II(Q)Cl] and [(arene)RuII(Q)(X)]BF4 compounds (arene = p-cymene, benzene, hexamethylbenzene; HQ = 1,3-dimethyl-4-R-(C=O)-5- pyrazolone, HQMe, R = methyl, HQPh, R = phenyl, HQ Naph, R = naphthyl; X = H2O, 9-ethylguanine), and their in vitro antitumor activity toward the cell lines MCF7 (HTB-22, human breast adenocarcinoma), HCT116 (CCL-247, human colorectal carcinoma), A2780 (human ovarian carcinoma), A549 (CCL-185, human lung carcinoma), and U87 MG (HTB-1, human glioblastoma). The X-ray crystal structures of two complexes were determined. One of them, {chlorido-(p-cymene)-[(1,3-dimethyl-4-(1-naphthoyl)- pyrazolon-5-ato]ruthenium(II)}, was also studied with density functional theory methods and was selected for docking on a DNA octamer showing intercalation between DNA bases by the naphthyl moiety and for Ru-N7(guanine) bonding.
