The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.15746-57-3, Name is Cis-Dichlorobis(2,2′-bipyridine)ruthenium(II), molecular formula is C20H16Cl2N4Ru.

The rate constants for photoinduced electron transfer, as well as thermal charge recombination, were measured in a series of <(4,4'-R2-2,2'-bipyridine)2RuII(4'-(CH3)-2,2'-bipyridine-4-(CONHR'))> (R’ = (CH2)x(MV2+) systems, in which a tris(bipyridyl)ruthenium(II) chromophore was covalently linked to a 4,4′-bipyridinium (MV2+) electron acceptor.The nature of R(R = H, CH3, COO-, COOH, CONHCH(CH3)2) and the number (x = 2,3) of intervening methylene units were varied to tune the chromophore’s electronic properties, including the ?* orbital energies of the 4,4′-R2-2,2′-bipyridine ligands and donor-acceptor separation distance, respectively.For a given donor-acceptor distance, x, and similar driving force, the rate constants for forward electron transfer were nearly 60 (x=3) to 400 (x=2) times smaller in complexes in which the two 4,4′-R2-2,2′-bipyridine ligands were R-substituted with electron-withdrawing functional groups (R = CONHCH(CH3)2).Charge recombination from the reduced viologen acceptor to the oxidized metal center occurs in the Marcus inverted region, with the rate constants (kb) decreasing with increasing magnitude of driving force.The kinetics of the bimolecular oxidative quenching of the electronically excited state of these mixed ligand tris(bipyridyl)ruthenium(II) complexes (R’ = CH(CH3)2) by methyl viologen was also characterized in homogeneous aqueous solution, and the escape efficiencies were measured for separation of the redox products from the solvent cage.

Four mono- (1?4) and four binuclear Ru(II) arene (5?8) complexes have been isolated from the reaction of [Ru(eta6-benzene)Cl(mu-Cl)]2 or [Ru(eta6-toluene)Cl(mu-Cl)]2 with 2-pyridinecarboxylic acid and 6-fluoro-2-pyridinecarboxylic acid. Their structural characterization included IR and NMR spectroscopy and MS spectrometry. The cytotoxic potential of the compounds has been tested by MTT assay in seven human cancer cell lines: alveolar basal adenocarcinoma (A549), large cell lung carcinoma (HTB177), colorectal carcinoma (HCT116), malignant melanoma (A375), prostate adenocarcinoma (PC3), breast carcinoma (MDA-MB-453), cervix adenocarcinoma (HeLa), and one human non-malignant lung fibroblast cell line (MRC-5). Mononuclear complexes 1 and 3 carrying 2-pyridinecarboxylic acid have displayed moderate antiproliferative effect toward HCT116 and HeLa, slightly better in comparison to their binuclear analogues, 5 and 7. The highest activity and cytoselectivity has been observed 1 as it has reduced viability of HCT116 cells 1.5 times more efficiently (IC50 = 27.5 muM), than of the MRC-5 cells (IC50 = 41.3 muM). In contrast to 1 and 3, compounds 2, 4?8 have been found to exhibit lack of cytotoxicity or mild cytotoxicity with IC50 values ranging from 100 to 300 muM.

Chiral porous zirconium phosphonates containing Ru-BINAP-DPEN moieties were 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 were used for enantioselective heterogeneous asymmetric hydrogenation of aromatic ketones with remarkably high ee values of up to 99.2%. These solid catalysts can also be easily recycled and reused for eight times without the loss of activity and enantioselectivity. Ready tunability of such a molecular building-block approach will allow the optimization of these hybrid materials and promise to lead to other practically useful heterogeneous asymmetric catalysts.

15746-57-3, Name is Cis-Dichlorobis(2,2′-bipyridine)ruthenium(II), molecular formula is C20H16Cl2N4Ru, belongs to ruthenium-catalysts compound, is a common compound. In a patnet, once mentioned the new application about 15746-57-3, category: ruthenium-catalysts

An NAD/NADH-functionalized ligand, benzo[b]pyrido[3,2-f][1,7]-phenanthroline (bpp), was newly synthesized. A Ru compound containing the bpp ligand, [Ru(bpp)(bpy)2]2+, underwent 2e- and 2H+ reduction, generating the NADH form of the compound, [Ru(bppHH)(bpy)2]2+, in response to visible light irradiation in CH3CN/TEA/H2O (8/1/1). The UV-vis and fluorescent spectra of both [Ru(bpp)(bpy)2]2+ and [Ru(bppHH)(bpy)2]2+ resembled the spectra of [Ru(bpy)3]2+. Both complexes exhibited strong emission, with quantum yields of 0.086 and 0.031, respectively; values that are much higher than those obtained from the NAD/NADH-functionalized complexes [Ru(pbn)(bpy)2]2+ and [Ru(pbnHH)(bpy)2]2+ (pbn = (2-(2-pyridyl)benzo[b]-1.5-naphthyridine, pbnHH = hydrogenated form of pbn). The reduction potential of the bpp ligand in [Ru(bpp)(bpy)2]2+ (-1.28 V vs SCE) is much more negative than that of the pbn ligand in [Ru(pbn)(bpy)2]2+ (-0.74 V), although the oxidation potentials of bppHH and pbnHH are essentially equal (0.95 V). These results indicate that the electrochemical oxidation of the dihydropyridine moiety in the NADH-type ligand was independent of the pi system, including the Ru polypyridyl framework. [Ru(bppHH)(bpy)2]2+ allowed the photoreduction of oxygen, generating H2O2 in 92% yield based on [Ru(bppHH)(bpy)2]2+. H2O2 production took place via singlet oxygen generated by the energy transfer from excited [Ru(bppHH)(bpy)2]2+ to triplet oxygen.

The new complexes [(eta6-arene)RuCl(C5H4N-2-CH=N-R)]PF6 (arene = C6H6 with R = 4- flourophenyl (1), 4-chlorophenyl (2), 4-bromophenyl (3), 4 -iodophenyl (4), 2, 5-dichlorophenyl (5) or p-cymene with R = 4-flourophenyl (6), 4-chlorophenyl (7), 4-bromophenyl (8), 4- iodophenyl (9), 2, 5 – dichlorophenyl (10)) have been synthesized by reacting the ruthenium arene precursors [(eta6-arene)Ru(mu-Cl)Cl]2, with the N,N?-bidentate ligands in a 1:2 ratio. Full characterization of all complexes was accomplished using 1H and 13C NMR, elemental analyses, UV-Vis spectroscopy, thermal analysis, IR spectroscopy and single crystal x-ray structures for compounds 7 and 10. The single crystal structures confirmed coordination of the ligand to the ruthenium(II) centre. The Ru(II) centre has a pseudo-octahedral three legged piano stool geometry in which the arene ring occupies the apex of the stool and the ruthenium is coordinated to the N,N?-bidentate ligand and a chloride ligand at the base of the stool. Two polymorphs of 7 were identified. The synthesized Ru(II) complexes were tested as catalysts for the oxidation of styrene to benzaldehyde using NaIO4 as a co-oxidant. All complexes were active catalysts for styrene oxidation and they gave high yields of benzaldehyde as the major product.

A cyclopentadienyl ruthenium(II) complex has been immobilized on MCM-41 modified with aminopropyl group through an amide bond formation reaction. FT-IR and UV-vis spectra show successful immobilization of cyclopentadienyl ruthenium complex onto the mesoporous silica surface by utilizing the amino group as a connector. The coordination state of the ruthenium complex is analyzed in detail by XAFS measurements, which indicate that the immobilization process does not influence its coordination geometry. Moreover, the retaining of long range ordering of the mesoporous structure of MCM-41 after grafting is evident from the results of XRD and N2 adsorption-desorption measurements. The resulting material promotes efficiently the hydrosilylation of 1-hexyne to produce vinylsilane with high alpha-selectivity under UV-irradiation at room temperature. Furthermore, the catalyst is recyclable for several catalytic runs without significant loss of its catalytic activity.
