A library of 32 organoruthenium compounds has been synthesised. Known and novel C-N cyclometalated compounds as well as N-C-N and N-N-C pincer derivatives of this metal have been used in this purpose. Most of the compounds have been tested for their in vitro antitumoral behaviours, good to excellent activities have thus been found. Several of the newly synthesized compounds pass the symbolic barrier of the nanomolar range for their IC50 indicating a critical improvement. The level of activity is tentatively correlated to physicochemical properties of the compounds such as their RuIII/II redox potential and their lipophilicity (logP).

Ruthenafuran and osmafuran monocationic complexes [Ru([14]aneS4)(C?O)]+ or [M(bpy)2(C?O)]+ (C?O = anionic bidentate chelate [C(OR)CHC(Ph)-O]-; [14]aneS4 = 1,4,8,11-tetrathiacyclotetradecane; M = Ru, Os; bpy = 2,2?-bipyridine) have been prepared from reactions between phenyl-ynone HC-C(CO)Ph and [Ru([14]aneS4)Cl2] or [M(bpy)2Cl2] in alcoholic solvents ROH. The formation of metal-vinylidene intermediate, followed by nucleophilic attack by RO-, and carbonyl group coordination to the metal center are believed to be the key steps in the formation of these metallafurans. The nature of the anionic C?O ligand was investigated by electrochemical, spectroscopic, and theoretical means.

A new 2-pyridyl-1,2,3-triazole (pytri) ligand, TPA-pytri, substituted with a triphenylamine (TPA) donor group on the 5 position of the pyridyl unit was synthesized and characterized. Dichloroplatinum(II), bis(phenylacetylide)platinum(II), bromotricarbonylrhenium(I), and bis(bipyridyl)ruthenium(II) complexes of this ligand were synthesized and compared to complexes of pytri ligands without the TPA substituent. The complexes of unsubstituted pytri ligands show metal-to-ligand charge-transfer (MLCT) absorption bands involving the pytri ligand in the near-UV region. These transitions are complemented by intraligand charge-transfer (ILCT) bands in the TPA-pytri complexes, resulting in greatly improved visible absorption (lambdamax = 421 nm and ? = 19800 M-1 cm-1 for [Pt(TPA-pytri)Cl2]). The resonance Raman enhancement patterns allow for assignment of these absorption bands. The [Re(TPA-pytri)(CO)3Br] and [Pt(TPA-pytri)(CCPh)2] complexes were examined with time-resolved infrared spectroscopy. Shifts in the C?C and C?O stretching bands revealed that the complexes form states with increased electron density about their metal centers. [Pt(TPA-pytri)Cl2] is unusual in that it is emissive despite the presence of deactivating d-d states, which prevents emission from the unsubstituted pytri complex.

The reaction of pyrimidine based electron-rich heterocyclic thiophene pyrazoles and halide bridged arene d6 metal precursors yielded a series of mononuclear and dinuclear half sandwich d6 metal complexes. Mononuclear and dinuclear complexes formed by the ratio-based reaction between ligand and metal precursor. All these cationic complexes have been characterized by IR, UV?Vis, 1H NMR, 13C NMR spectroscopic techniques. Complex 5 has been established by single-crystal analysis. X-ray diffraction studies revealed the formation of mononuclear and dinuclear complexes and suggest that the vicinity around the metal atom is distorted octahedral. An in vitro study to screen the antibacterial potential of these complexes against pathogenic bacteria, S. aureus, K. pneumoniae, and E. coli was addressed. All the complexes display a better zone of inhibitions for both Gram-positive (S. aureus) and Gram-negative strains (K. pneumoniae, and E. coli). The minimum inhibitory concentrations (MICs) for the most active complex ranged from 0.125 to 0.25 mg/ml for S. aureus and Klebsiella Pneumoniae and 0.25?0.5 mg/ml for E. coli.

Electric Literature 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.

Using rational design, an engineered myoglobinbased catalyst capable of catalyzing the cyclopropanation of aryl-substituted olefins with catalytic proficiency (up to 46800 turnovers) and excellent diastereo- and enantioselectivity (98-99.9%) was developed. This transformation could be carried out in the presence of up to 20 gL-1 olefin substrate with no loss in diastereo- and/or enantioselectivity. Mutagenesis and mechanistic studies support a cyclopropanation mechanism mediated by an electrophilic, heme-bound carbene species and a model is provided to rationalize the stereopreference of the protein catalyst. This work shows that myoglobin constitutes a promising and robust scaffold for the development of biocatalysts with carbene-transfer reactivity.

Three novel luminescent piano-stool arene ruthenium complexes of general formula [(eta6-arene)RuCl2(CPI)] (eta6- arene = benzene, 1, p-cymene, 2, and hexamethylbenzene, 3; CPI=1-(4-cyanophenyl) imidazole were prepared. The molecular structures of 2 and 3 were determined crystallographically. Reaction of 1-3 with EPh3 (E = P, As, or Sb) and N-N donor bases such as 2,2?-bipyridine and 1,10-phenanthroline afforded cationic mononuclear complexes of general formula [(eta6- arene)RuCl(CPI)(EPh3)]+ (eta6-arene = C 6H6, E = P (1a), E = As (1b), E = Sb (1c); eta6-arene = C10H14, E = P (2a), E = As (2b), E = Sb (2c); eta6-arene = C6Me6, E = P (3a), E = As (3b), E = Sb (3c)) and [(eta6-arene)Ru(N-N)(CPI)] 2+ (eta6-arene = C6H6, N-N = bipy (1d), N-N = phen (1e); eta6-arene = C10H14, N-N = bipy (2d), N-N = phen (2e); eta6-arene = C6Me 6, N-N = bipy (3d), N-N = phen (3e)). Molecular structures of 1a and 2a were also confirmed by X-ray crystallography. Structural studies of the complexes 2, 3, 1a, and 2a supported coordination of CPI through the imidazole nitrogen and the presence of a pendant nitrile group. Structural data also revealed stabilization of crystal packing in the complexes 2, 3, and 2a by C-H…X (X = Cl, F) type inter- and intramolecular interactions and in complex 1a by pi-pi stacking. Moreover, neutral homonuclear bimetallic complexes 2f,g were prepared by using complex 2 as a metallo-ligand, where CPI acts as a bridge between two metal centers. Emission spectra of the mononuclear complexes [(eta6-arene)RuCl2(CPI)] and its derivatives exhibited intense luminescence when excited in the metal to ligand charge-transfer band.

We report here new examples of enantiomerically pure monodendate phosphinite ligands containing both a ferrocene moiety and NH bridging moiety adjacent to the stereocenter, as well as their ruthenium(II) dichloro complexes. The phosphinites based on ferrocenyl moiety possessing stereogenic center have been screened as ligands for ruthenium(II)-catalyzed transfer hydrogenation of aromatic ketones to give corresponding secondary alcohols using iso-PrOH as the hydrogen source in the presence of NaOH. Up to 99% conversion with 97% ee was obtained in the transfer hydrogenation of acetophenone derivatives. Furthermore, the catalytic properties of these catalysts based on ferrocenyl-phosphinite backbone are also discussed briefly. The structures of these ligand and their corresponding complexes have been elucidated by a combination of multinuclear NMR spectroscopy, IR spectroscopy and elemental analysis.

Treatment of [(eta6-C6H6)RuCl2]2 or [(eta6-p-cymene)RuCl2]2 with two equiv. of L-methionine in the presence of AgNO3 and NaOMe gave mononuclear ruthenium(II) complexes [(eta6-C6H6)Ru(L-met)](NO3) (1) and [(eta6-cymene)Ru(L-met)](NO3) (2), respectively. Interactions between equal equiv. of L-methionine and [Ru(CO)2Cl2]n, [Ru(bpy)2Cl2]·2H2O (bpy = 2,2?-bipyridine), [Ru(NO)(PPh3)2Cl3], (Et4N)[Ru(CH3CN)2Cl4] or cis-[Ru(DMSO)4Cl2] (DMSO = dimethylsulfoxide) resulted in isolation of the expected ruthenium complexes [(CO)2Ru(L-met)Cl] (3), [(bpy)2Ru(L-met)]Cl (4), [Ru(L-met)(NO)(PPh3)Cl]Cl (5), [Ru(L-met)(CH3CN)Cl2] (6) and [Ru(L-met)(DMSO)2Cl] (7), respectively. Reaction of [Ru(COD)Cl2]2 (COD = 1,5-cyclooctadiene) with L-methionine gave a dinuclear ruthenium complex [(COD)Ru(mu-S-L-met)(mu-Cl)RuCl(L-metNMe2)] (8). Complexes 1?8 were characterized by microanalyses, IR, NMR and UV?vis spectroscopies. The structures of complexes 1, 2, 4 and 8 have been unambiguously established by single-crystal X-ray crystallography.

A novel microwave-assisted synthetic method has been used to synthesise a series of mixed ligand ruthenium(II) compounds containing diimine as well as bidentate thiosemicarbazone ligands. The compounds contain the diimine 1,10-phenanthroline (phen) or 2,2?-bipyridine (bpy) and the thiosemicarbazone is derived from 9-anthraldehyde. Based on elemental analyses and spectroscopic data, the compounds are best formulated as [(phen) 2Ru(thiosemicarbazone)](PF6)2 and [(phen) 2Ru(thiosemicarbazone)](PF6)2 where thiosemicarbazone = 9-anthraldehydethiosemicarbazone, 9-anthraldehyde-N(4)- methylthiosemicarbazone, and 9-anthraldehyde-N(4)-ethylthiosemicarbazone. Fluorescence competition studies with ethidium bromide, along with viscometric measurements suggests that the complexes bind calf thymus DNA (CTDNA) relatively strongly via an intercalative mode possibly involving the aromatic rings of the diimine ligands. The complexes show good cytotoxic profiles against MCF-7 and MDA-MB-231 (breast adenocarcinoma) as well as HCT 116 and HT-29 (colorectal carcinoma) cell lines. The Royal Society of Chemistry 2009.
