Reactions of [{Ru(eta3:eta3-C10H 16)(mu-Cl)Cl}2] with 1,4-dicyanobenzene (DCB) or 1,4-piperazinedicarbonitrile (PPz) in dichloromethane in 1:2 and 1:1 molar ratio gives mononuclear complex [Ru(eta3:eta3-C10H16)Cl 2(L)] and binuclear complex [{Ru(eta3:eta3-C10H16)Cl 2}2(mu-L)]. However, its reaction with 1,4-dicyanotrans-2-butene (DCBT) gives only a binuclear complex [{Ru(eta3:eta3-C10H16)Cl 2}2(mu-DCBT)] and with 1-piperidinecarbonitrile (PPd), a mononuclear complex [Ru(eta3:eta3-C10H16)Cl 2(L)]. The mononuclear complexes resulting from the reaction of [{Ru(eta3:eta3-C10H 16)(mu-Cl)Cl}2] with DCB or PPz possesses pendant nitrile group. Nucleophilicity of the pendant nitrile group in these complexes have been employed in the synthesis of binuclear mixed valence-bridged complexes, in which, the respective metal centers are bridged by DCB or PPz ligand. The reaction products have been characterized by microanalyses and spectroscopic studies (IR, 1H NMR and 13C NMR spectra).

In a Article，once mentioned of 37366-09-9, COA of Formula: C12H12Cl4Ru2

Only four types of dimeric precursors [RuCl2(eta6-arene)]2 for the synthesis of Noyori’s half sandwich diamine catalysts [RuCl(TsDPEN)(eta6-arene)] are commercially available, yet so far no study has tried to systematically evaluate how these systems perform during the asymmetric transfer hydrogenation of various 3,4-dihydroisoquinolines (i.e., the typical substrates for Noyori asymmetric transfer hydrogenation benchmarking). Experiments combined with molecular modeling allowed us to assess their properties and formulate a hypothesis clarifying the difference in enantioselectivity of these systems.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.COA of Formula: C12H12Cl4Ru2, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 37366-09-9, in my other articles.

In a Article，once mentioned of 15746-57-3, name: Cis-Dichlorobis(2,2′-bipyridine)ruthenium(II)

We have investigated the electrochemical, spectroscopic and electroluminescent properties of a family of aza-aromatic complexes of ruthenium of type [RuII(bpy/phen)2(L)]2+ (4d6) with three isomeric L ligands, where, bpy = 2,2?-bipyridine, phen = 1,10-phenanthroline and the L ligands are 3-(2-pyridyl)[1,2,4]triazolo[1,5-a]pyridine (L1), 3-(2-pyridyl[1,2,3])triazolo[1,5-a]pyridine (L2) and 2-(2-pyridyl)[1,2,4]triazolo[1,5-a]pyridine (L3). The complexes display two bands in the visible region near 410-420 and 440-450 nm. The complexes are diamagnetic and show well defined 1H NMR lines. They are electroactive in acetonitrile solution and exhibit a well defined RuII/RuIII couple near 1.20 to 1.30 V and -1.40 to -1.50 V due to ligand reduction versus Saturated Calomel Electrode (SCE). The solutions are also luminescent, with peaks are near 600 nm. All the complexes are electroluminescent in nature with peaks lying near 580 nm. L1 and L3 ligated complexes with two bpy co-ligands show weak photoluminescence (PL) but stronger electroluminescence (EL) compared to corresponding L2 ligated analogues.

Half sandwich ruthenium, rhodium and iridium complexes containing pyridyl chalcone analogues (L1 and L2) are prepared by the reaction of [(arene)M(mu-Cl)Cl]2 (arene = benzene, p-cymene, Cp*) and (M = Ru, Rh/Ir)] with L1 and L2 in 1:2 (M:L) ratio. Eight neutral mononuclear complexes (1?8) were obtained and characterized using FT-IR, 1H NMR, 13C NMR, ESI mass and UV?Vis spectroscopic methods. The molecular structures of complexes 2, 4, 5 and 7 are established by single crystal X-ray diffraction studies. Antibacterial studies were tested against three strains of bacterial microorganisms Staphylococcus aureus (gram +ve), Klebsiella pneumoniae (gram ?ve) and Escherichia coli (gram ?ve).

In search for antitumor metal-based drugs that would mitigate the severe side-effects of cisplatin, Ru(II) complexes are gaining increasing recent interest. In this work, we report on the synthesis, characterization (1H- and 13C-NMR, FT-IR), and cytotoxicity studies of two new half-sandwich organometallic Ru(II) complexes of the general formula [Ru(eta6-arene)(XY)Cl](PF6) where arene = benzene or toluene and XY = bidentates: dipyrido[3,2-a:2?,3?-c]phenazine (dppz) or 2-(9-anthryl)-1H-imidazo[4,5-f][1,10]phenanthroline (aip), which are bound to Ru(II) via two phenanthroline-N atoms in a characteristic ?piano-stool? configuration of Ru(II)-arene complexes?as confirmed by vibrational and NMR spectra. In addition, cytotoxic studies were performed for similar half-sandwich organometallic [Ru(eta6-p-cymene)(Me2dppz)Cl]PF6 complex (Me2dppz = 11,12-dimethyl-dipyrido[3,2-a:2?,3?-c]phenazine). This study is complemented with elaborate modeling with density functional theory (DFT) calculations, which provided insight into reactive sites of Ru(II) structures, further detailed by molecular docking on the B-DNA dodecamer, which identified binding sites and affinities: most pronounced for the [Ru(eta6-benzene)(aip)Cl](PF6) in both A-T and G-C regions of the DNA minor groove. Cytotoxic activity was probed versus tumor cell lines B16, C6, and U251 (B16 mouse melanoma, C6 rat glioma, U251 human glioblastoma) and non-tumor cell line HACAT (HACAT normal human keratinocytes).

New benzene ruthenium(II) aroylhydrazone complexes of general molecular formula [Ru(eta6-C6H6)Cl(L)] (where L = aroylhydrazone ligand) have been synthesized from the reaction of the precursor [Ru(eta6-C6H6)(mu-Cl)Cl]2and aroylhydrazone ligands. The composition of the complexes has been accomplished by elemental analysis and spectral methods (FT-IR, UV-Vis,1H NMR). The molecular structure of complex 4 has been established by single-crystal X-ray structure analysis shows that the aroylhydrazone ligands are coordinated to ruthenium as a bidentate N, O donor and a typical piano stool geometry was observed around ruthenium(II) metal center. All the complexes exhibit two consecutive irreversible oxidations in the potential range +0.74 to +1.17 V (RuII/RuIII;RuIII/RuIV) Vs calomel electrode. Further, in vitro anticancer activity of complexes 1-4 on human breast cancer cell line (MCF-7), human cervical cancer cell line (HeLa) and non-cancerous NIH-3T3 cell line exhibit moderate to excellent cytotoxic activity. It is also evident from IC50values that the complexes are more potent against MCF-7 cells than cisplatin. The superior activity of the complex 4 assumes that presence of electron donating methoxy substituent which makes the ring more reactive. Further, the morphological changes during cell death were investigated by Acridine Orange-Ethidium Bromide (AO-EB) and DAPI staining techniques, which confirm the complex 4 induces cell death only through apoptosis.

We report a sustainable in vitro system for enzyme-based photohydrogen production. The [FeFe]-hydrogenase HydA1 from Chlamydomonas reinhardtii was tested for photohydrogen production as a proton-reducing catalyst in combination with eight different photosensitizers. Using the organic dye 5-carboxyeosin as a photosensitizer and plant-type ferredoxin PetF as an electron mediator, HydA1 achieves the highest light-driven turnover number (TONHydA1) yet reported for an enzyme-based in vitro system (2.9×106 mol(H2) mol(cat)?1) and a maximum turnover frequency (TOFHydA1) of 550 mol(H2) mol(HydA1)?1 s?1. The system is fueled very effectively by ambient daylight and can be further simplified by using 5-carboxyeosin and HydA1 as a two-component photosensitizer/biocatalyst system without an additional redox mediator.
