(Chemical Equation Presented) Oxidation without organics: A tetraruthenium polyoxometalate (see picture; Ru blue, O red, Si yellow, W black) catalyzes the rapid oxidation of H2O to O2 in water at ambient temperature, and shows considerable stability under turnover conditions. The complex was characterized by several methods, including X-ray crystallography and cyclic voltammetry.

The bis(oxazoline) ligand, 2,2-bis[4(R)-phenyl-1,3-oxazolon-2-yl]propane (bpop), was introduced to the eta6-benzeneruthenium(II) moiety on treatment with [Ru(eta6-C6H6)Cl2]2 to give [Ru(eta6-C6H6) (bpop)Cl]+. Aquo and amine complexes [Ru(eta6-C6H6) (bpop) (L)]2+ (L=H2O (1), NH2R; R=H (2), Me (3), and n-Bu (4)) were prepared by treating the chloride complex with AgBF4 in the presence of L. X-ray structure determinations of 1 and 3 were carried out. Both complexes possessed a three-leg piano stool structure with the N or O donors located at the three corners of a pseudo octahedron. The aquo complex 1 exhibited a dynamic NMR feature in which two magnetically non-equivalent oxazoline parts observed at lower temperatures were interchanged with each other at higher temperatures. This observation was ascribed to the formation of a C2-symmetric 16-electron intermediate via Ru-OH2 cleavage, which is slower in acetone than in dichloromethane owing to more effective solvation by acetone around hydrogens of the coordinated water molecule. The two diastereotopic N-hydrogens of 4 underwent deuterium exchange with CD3OD with greatly different rates from each other owing to different energy of NH…O(D)(CD3) interaction. Carboxylate and sulfonate ions (A-) formed second sphere complexes with 4 by means of NH…A- hydrogen bonding, as evidenced by continuous shift of NH2 resonances with increasing amounts of the anions added.

New Ruthenium complexes I, II and III were synthesized using 5-chlorothiophene-2-carboxylic acid (5TPC), as ligand and the complexes were characterized by elemental analysis, FT-IR, 1H, 13C NMR, and mass spectroscopic techniques. Photophysical and electrochemical studies were carried out and the structures of the synthesized complex were optimized using density functional theory (DFT). The molecular geometry, the highest occupied molecular orbital (HOMO), the lowest unoccupied molecular orbital (LUMO) energies and Mulliken atomic charges of the molecules are determined at the B3LYP method and standard 6-311++G (d,p) basis set starting from optimized geometry. They possess excellent stabilities and their thermal decomposition temperatures are 185 C, 180 C and 200 C respectively, indicating that the metal complexes are suitable for the fabrication processes of optoelectronic devices.

Cationic ruthenium dihydrogen complexes of the form [(eta-C5H5)Ru(L)(L?)(eta2-H 2)]BF4 (L = CO, L? = PCy3 (1a), PPh3 (2a), PMe2Ph (3a), PMe3 (4a) have been prepared by protonation of the corresponding neutral hydrides. Carbonyl free derivatives such as [(eta-C5H5)Ru(P P?)(eta2-H2)]BF4 (P P? = 1,2-bis(dimethylphosphino)ethane (dmpe) (5a), (1,1-dimethyl-2,2-diphenylphosphino)ethane (dmdppe) (6a), (R)-(+)-1,2-bis(diphenylphosphino)propane ((R)-prophos) (8a), bis(PPh3) (9a)) were similarly prepared. Pentamethylcyclopentadienyl analogues [(eta-C5Me5)Ru(P P?(eta2-H2)]BF4 (P P? = dmdppe (7a), (PPh3J2 (10a)) and [(eta-C5Me5)Ru(CO)(PCy3)(eta 2-H2)]BF4 (11a) have also been prepared. Identification of these species as dihydrogen complexes is based upon observation of substantial H-D coupling (22-32 Hz) in the 1H NMR spectra of the HD analogues, prepared by protonation of the corresponding deuterides. In every case studied in detail, the kinetic product of the protonation reaction is the dihydrogen complex, but an intramolecular isomerization occurs to give variable amounts of the transoid dihydride form at equilibrium. The composition of the equilibrium mixture and the rate at which the equilibrium is obtained depend upon the ligand environment. Facile rotation of the coordinated H2 ligand in the ruthenium complexes is established by the study of chiral complexes. The coordinated H2 in these complexes is substantially activated toward heterolytic cleavage. In the case of 5a, the measured pKa is 17.6 (CH3CN), with the dihydrogen form deprotonated more rapidly than the dihydride.

Porphyrins are used as photosensitizing agents in photodynamic therapy (PDT) for several pathologies. Here we demonstrate the DNA photocleavage and cytotoxicity properties of a free-base meso-tetra-ruthenated porphyrin (H2RuTPyP) in purified DNA samples and in a melanoma cell line, respectively. Cytotoxicity of H2RuTPyP was investigated by the tetrazolium dye (MTT) colorimetric assay and its genotoxic potential by direct plasmid DNA photocleavage after incubation with specific DNA repair enzymes. H2RuTPyP porphyrin efficiently induced DNA damage at the lower concentration of 5.0 muM, whereas it induced complete DNA degradation at 15 muM. The addition of different scavengers for reactive oxygen species (ROS) during the visible light exposures did not decrease the DNA damage formation, suggesting a hydrolytic mechanism for the induction of DNA breaks. Also, H2RuTPyP exhibited a much higher cytotoxicity in melanoma cells in comparison to a keratinocyte cell line. The detection of intracellular reactive oxygen species (ROS) produced by H2RuTPyP through the DCF-DA assay also suggests that ROS have a minor role in the induction of cytotoxicity. Therefore, H2RuTPyP seems to be a very effective photosensitizer, representing a promising alternative for the development of new skin cancer treatments using PDT process.

The neutral ruthenium complexes Cp?Ru(PR3)2Cl [Cp? = Cp, PR3 = PPh3, PMe3, or 1/2 dppe; Cp? = Cp*, PR3 = PMe3] react with [p-MeOC6H4N2][BF4] in acetone to give new cyclopentadienyl ruthenium aryldiazenido dicationic complexes [Cp?Ru(PR3)2(N2C6H 4OMe)]-[BF4]2 [Cp? = Cp, PR3 = PPh3 (1), PMe3 (2), or 1/2 dppe (3); Cp? = Cp*, PR3 = PMe3 (4)] in good yields. The dicationic complexes 1-3 may also be conveniently isolated in better yield by treatment of the acetonitrile ruthenium complexes [CpRu(PR3)2(NCMe)][BF4] with the arenediazonium salt. When the reaction of Cp?Ru(PPh3)2Cl (Cp? = Cp or Cp*) with [p-MeOC6H4N2][BF4] is carried out in toluene, the product is instead the cyclopentadienyl ruthenium aryldiazenido monocationic complex [Cp?RuCl(PPh3)(N2C6H 4OMe)][BF4] [Cp? = Cp (5) or Cp* (6)]. Further, if the reaction of Cp*Ru(PPh3)2Cl with diazonium salt is carried out in acetone, the binuclear complex [Cp*RuCl(N2C6H4OMe)]2[Cl] 2 (7) can be isolated in low yield in addition to 6. All new complexes 1-7 were fully characterized by NMR, FT-IR, and mass spectroscopies. The structure of [CpRu(PPh3)2(N2C6H 4OMe)][BF4]2·0.93CHCl3 (1· 0.93CHCl3) was determined by single-crystal X-ray diffraction. The structure exhibits a near-linear Ru-N-N-C geometry for the coordinated aryldiazenido group, with the NNC angle having a value of 159, compared to the “sp2” value of approximately 120 commonly exhibited by other “singly bent” aryldiazenido complexes. On the basis of NMR spectroscopic data, 1 reacts with NaBH4 at low temperature to give an arylhydrazido(2-) complex [CpRu(PPh3)2-{NN(H)C6H4OMe}][BF 4], which readily converts to the corresponding aryldiazene complex [CpRu(PPh3)2(NH=NC6H4OMe)][BF 4] by a hydrogen shift; at room temperature, the only product is the hydrido complex CpRuH(PPh3)2.
