Reference of 37366-09-9, 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.37366-09-9, Name is Dichloro(benzene)ruthenium(II) dimer, molecular formula is C12H12Cl4Ru2. In a patent, introducing its new discovery.

Halfsandwich complexes of ruthenium, rhodium and iridium with deprotonated N,N?,N?-tripeptide ester ligands were obtained from chloro bridged compounds and tripeptide methyl esters (1-6) or by peptide synthesis at a metal centre (9-15). For the peptide synthesis at the complex (C6Me6)Ru coordinated dipeptide methyl esters from glycine and beta-alanine or gamma-amino butyric acid were elongated by an alpha-amino acid methylester. The tripeptide ester Ru(eta6-C6Me6) complexes with chiral amino acid components and an “asymmetric” metal atom are formed with high diastereoselectivity. The tripeptide esters Gly-Gly-beta-AlaOMe, Val-Gly-beta-AlaOMe and Phe-Gly-beta-AlaOMe can be condensated at the (C6Me6)Ru complex with sodium methanolate to give triple deprotonated cyclic tripeptides.

Synthetic Route of 15746-57-3, An article , which mentions 15746-57-3, molecular formula is C20H16Cl2N4Ru. The compound – Cis-Dichlorobis(2,2′-bipyridine)ruthenium(II) played an important role in people’s production and life.

A new Ru(II) bipyridyl complex with O4-hydrogenpyridine-2,4-dicarboxylate was synthesized and characterized by IR, NMR and mass spec-trometry, X-ray diffraction analysis and elemental analysis. The electrochemical characteristics of the complex were investigated by cyclic voltammetry, revealing Ru(II)/Ru(III) electron transfer in the positive range of potentials. On the opposite potential side, multiple partially reversible peaks were dominant, representing subsequent reductions of the bulky bipyridyl moiety. The cyto-toxic activity of the complex was tested in two human cancer cell lines: A549 (lung cancer) and K562 (leukemia) as well as non-tumor MRC-5 cells, by MTT assays. The IC50 values were > 300 and 177.63±2.28 muM for the A549 and K562 cells, respectively.

Spectroscopic and electrochemical investigations have been carried out on a collection of hydrogen-bonded mixed-valence adducts of ruthenium complexes. The electron donors (H-bond acceptors) are Ru(II) cyano species and the electron acceptors (H-bond donors) are Ru(III) ethylenediamine species, and NIR spectroscopic transitions in the adducts are assigned to intervalence transfer through the hydrogen bonds holding the adducts together (HBIT). Spectroscopic studies using Job’s method indicate that the adducts are 2:1 ternary aggregates of formulations such as [((trpy)(bpy)Ru(II)(CN))2,(en)2Ru(III)(bpy)]5+ and [((bpy)2Ru(II)(CN)2)2,(en)2Ru(III)(bpy)]3+. Voltammetric investigations show substantial repulsion of the redox waves of the parent complexes in mixtures containing both donor and acceptor. Comparison with known electronic coupling data for mixed-valence ruthenium dimers covalently bound through dithiaspiroalkane bridging ligands indicates that the electronic coupling through H bonds of this type is 65-75% as strong as through sigma-covalent bonds.

The effects of replacing a single polypyridyl ligand with an analogous anionic cyclometalating ligand were Investigated for a set of three structurally related series of Ru(II) compounds formulated as [Ru(bpy)2(L)] z, [Ru(tpy)(L)]z, and [Ru(tpy)(L)Cl]z, where z=0, -1, or +2, and L = polypyridyl (e.g., bpy=2,2′-blpyridlne, tpy = 2,2′:6′,2″-terpyridine) or cyclometalating ligand (e.g., deprotonated forms of 2-phenylpyridlne or 3-(2-pyridinyl)-benzoic acid). Each of the complexes were synthesized and characterized by1H NMR spectroscopy, electrospray ionization mass spectrometry (ESI-MS), and/or elemental analyses (EA). Cyclic voltammetry reveals that cyclometalation causes a shift of the first oxidation and reduction potentials by -0.5 to -0.8 V and -0.2 to -0.4 V, respectively, relative to their polypyridyl congeners. These disparate shifts have the effect of inducing a bathochromic shift of the lowest-energy absorption bands by as much as 90 nm. With the aid of time-dependent density functional theory (DFT), the lowest-energy bands (lambdamax = 500-575 nm) were assigned as predominantly metal-to-ligand charge-transfer (MLCT) transitions from Ru to the polypyridyl ligands, while Ru?C^N(or C^N^Nor N^C^N transitions are found within the absorption bands centered at ca. 400 nm. The properties of a series of compounds furnished with carboxylic acid anchoring groups at various positions are also examined for applications Involving the sensitization of metal-oxide semiconductors. It Is determined that the thermodynamic potentials of many of these compounds are appropriate for conventional photoelectrochemical cells (e.g., dye-sensitized solar cells) that utilize a titania electrode and iodide-based electrolyte.

A pair of novel optically pure phosphinite ligands were synthesized by ring opening reaction of chiral amines with (R)-styrene oxide or (S)-glycidyl phenyl ether oxide using a straightforward method in high yields and their ruthenium complexes were described in detail. The ruthenium complexes proved to be highly efficient catalysts for the enantioselective hydrogenation of ketones, affording products up to 99% ee. The results showed that the corresponding chiral alcohols could be obtained with high activity and excellent enantioselectivities at the desired temperature.

Metal-catalyzed asymmetric transfer hydrogenation is a powerful and practical method for the reduction of ketones to produce the corresponding secondary alcohols, which are valuable building blocks in the pharmaceutical, perfume, and agrochemical industries. Hence, a series of novel chiral beta-amino alcohols were synthesized by chiral amines with regioselective ring opening of (S)-propylene oxide or reaction with (S)-(+)-2-hydroxypropyl p-toluenesulfonate by a straightforward method. The chiral ruthenium catalytic systems generated from [Ru(arene)(mu-Cl)Cl]2 complexes and chiral phosphinite ligands based on amino alcohol derivatives were employed in asymmetric transfer hydrogenation of ketones to give the corresponding optically active alcohols; (2S)-1-{[(2S)-2-[(diphenylphosphanyl)oxy]propyl][(1R)-1-phenylethyl]amino}propan-2-yldiphenylphosphinitobis[dichol-oro(eta6-benzene)ruthenium(II)] acts an excellent catalyst in the reduction of alpha-naphthyl methyl ketone, giving the corresponding alcohol with up to 99% ee. The substituents on the backbone of the ligands were found to have a remarkable effect on both the conversion and enantioselectivity of the catalysts. Furthermore, this transfer hydrogenation is characterized by low reversibility under these conditions.
