The ruthenium(III) chloride catalyzed oxidation of butanone-2 and pentanone-3 by aqueous cerium(IV) was found to be first order with respect to ketone concentration.The rate is inversely proportional to the square of sulfuric acid concentration but reaction velocity shows first-order behaviour at lower concentrations.The linear dependence of the reaction rate at lower ruthenium(III) concentrations tends toward zero order at higher concentrations.These data suggest that the oxidation of these ketones proceeds via the formation of an activated complex between ruthenium(III) and protonated ketones which rapidly decomposes, followed by a fast reaction between ruthenium(III) hydride and the cerium(IV) species.

Herein we report the discovery of an in situ generated, highly active nanocatalyst for the room temperature dehydrogenation of dimethylamine-borane in water. The new catalyst system consisting of ruthenium(0) nanoparticles stabilized by the hydrogenphosphate anion can readily and reproducibly be formed under in situ conditions from the dimethylamine-borane reduction of a ruthenium(iii) precatalyst in tetrabutylammonium dihydrogenphosphate solution at 25 ± 0.1 C. These new water dispersible ruthenium nanoparticles were characterized by using a combination of advanced analytical techniques. The results show the formation of well-dispersed ruthenium(0) nanoparticles of 2.9 ± 0.9 nm size stabilized by the hydrogenphosphate anion in aqueous solution. The resulting ruthenium(0) nanoparticles act as a highly active catalyst in the generation of 3.0 equiv. of H2 from the hydrolytic dehydrogenation of dimethylamine-borane with an initial TOF value of 500 h -1 at 25 ± 0.1 C. Moreover, they provide exceptional catalytic lifetime (TTO = 11600) in the same reaction at room temperature. The work reported here also includes the following results; (i) monitoring the formation kinetics of the in situ generated ruthenium nanoparticles, by using the hydrogen generation from the hydrolytic dehydrogenation of dimethylamine-borane as a catalytic reporter reaction, shows that sigmoidal kinetics of catalyst formation and concomitant dehydrogenation fits well to the two-step, slow nucleation and then autocatalytic surface growth mechanism, A ? B (rate constant k1) and A + B ? 2B (rate constant k 2), in which A is RuCl3·3H2O and B is the growing, catalytically active Ru(0)n nanoclusters. (ii) Hg(0) poisoning coupled with activity measurements after solution infiltration demonstrates that the in situ generated ruthenium(0) nanoparticles act as a kinetically competent heterogeneous catalyst in hydrogen generation from the hydrolytic dehydrogenation of dimethylamine-borane. (iii) A compilation of kinetic data depending on the temperature and catalyst concentration is used to determine the dependency of reaction rate on catalyst concentration and the activation energy of the reaction, respectively.

Certain dienynes give cyclorearrangement by tandem cyclopropanation/ring-closing alkene metathesis, triggered by either a ruthenium carbene or noncarbene ruthenium(II) precatalyst. The process represents a variation of enyne metathesis where presumed cyclopropyl carbene intermediates undergo a consecutive ring-closing metathesis. A mechanistic proposal is offered, and sequential use of catalysts provided a tandem ring-closing enyne/alkene metathesis product. Copyright

We performed measurements of magnetic susceptibility, electrical resistivity, and magnetoresistance in magnetic fields of up to 18 T in the magnetic superconductor RuGd1.4Ce0.6Sr2Cu2O10 – delta synthesized in oxygen pressures up to 95 atm. The magnetic-susceptibility data show the occurrence of an antiferromagnetic state below TN? 175 K, followed by the development of a weak ferromagnetic state near TM ? 100 K, and followed further by the onset of superconductivity (SC) at Tc ? 42 K. The electrical resistivity as a function of temperature shows an evolution from nonmetal-to-SC behavior in samples prepared in a flux of O2 to a well defined metal-like behavior in samples prepared under 95 atm pressure of O2. The electron-phonon coupling constant was calculated from transport data to be lambdatr?0.17, a value comparable with other cuprates, indicating weak electron-phonon coupling in these ruthenates. The values of the upper critical field Hc2 for the O2 high-pressure treated samples were obtained from the magnetoresistivity data yielding Hc2ab(0)?39 T, and the out-of-plane superconducting coherence length xic(0) ? (0) ? 28 A . Based on the similarities between these ruthenates and the superconductor YBa2Cu3O7 – delta, we estimated Hc2c(0) ? 8 T and xiab(0) ? 140 A . We used these parameters to discuss the coexistence of long-range magnetic order and superconductivity on a microscopic scale on these materials.

Two new heteroleptic ruthenium(ii) photosensitizers that contains 2,2?;6,2??-terpyridine with extended pi-conjugation with donor groups, a 4,4?-dicarboxylic acid-2,2?-bipyridine anchoring ligand and a thiocyanate ligand have been designed, synthesized and fully characterized by CHN, mass spectrometry, UV-vis and fluorescence spectroscopies and cyclic voltammetry. The new sensitizers have either 3,5-di-tert-butyl phenyl (m-BL-5) or triphenylamine (m-BL-6) groups, where the molar extinction coefficient of both the sensitizers is higher than the analogous ruthenium dyes. Both the sensitizers were tested in dye-sensitized solar cells using two different redox electrolytes.

These Salts have been characterized by elemental analyses, molar conductance, magnetic susceptibility, IR and UV-visible spectral studies. X-ray diffraction patterns indicate their non-isomorphous nature. All the complexes behave as semiconductors as their solid-state conductivities were found to increase with the increase in temperature from 305 to 393 K.

A document type is Article, introducing its new discovery.

This study examined the conversions, via oxidative fusion or coupling, of B5H81- to B10H14 and 2,2′-(B5H8)2 in the presence of FeCl2/FeCl3, of B5H81- to B10H14 alone in the presence of RuCl3, and of 1-XB5H71- (X = D and CH3) to 2,4-B10H12D2 and 2,2-(1-CH3B5H7)2 with RuCl3 or FeCl2/FeCl3.The B10H131- ion was shown to form n- and i-B18H22 on treatment with RuCl3 in THF and subsequent exposure to air.The RuCl3-promoted fusions of the square-pyramidal cobaltaboranes 2-(epsilon5-C5H5)CoB4H71- and 1-(epsilon5-C5H5)CoB4H71- (both analogues of B5H81- to give nido-(eta-C5H5)2Co2B8H12 isomers were also studied.The 2-isomer yields primarily 5,8-, 1,5-, and 1,7-(eta-C5H5)2Co2B8H12, while the 1-isomer affords only 2,4-(eta5-C5H5)2Co2B8H12.All these observations support a fusion mechanism in which two square-pyramidal substrate molecules, facilitated by coordination to a common metal ion, are initially joined at their basal edges and then complete the fusion process to give a nido 10-vertex cage in which the original apex (1-vertex) atoms become the 2,4-vertexes in the product.The new compounds were characterized via infrared, 11B and 1H NMR, mass spectra, and in some cases by two-dimensional (2D) 11B homonuclear NMR.

Resonance Raman (RR) and optical spectroelectrochemical titrations of the cis,cis-[(bpy)2Ru-(OH2)]2O4+ ion (denoted [3,3] to indicate the formal oxidation state of the Ru-O-Ru unit) were made over the range 0.8-2.0 V vs Ag/AgCl in 0.5 M trifluoromethanesulfonic acid; the results revealed sequential accumulation of three higher oxidation states. Two of these states were identified by redox titration with Os(bpy)32+ as one-electron ([3,4]) and four-electron oxidized species ([5,5]); spectroscopic analysis of reaction products formed upon mixing the [3,3] and [5,5] ions indicated that the third oxidation state is a two-electron oxidized species ([4,4]). The [5,5] ion underwent first-order decay to the [4,4] ion with a rate constant, k ? 9.5 x 10-3 s-1, that was nearly identical with the catalytic turnover rate for O2 evolution, k(cat) ? 1.3 x 10-2 s-1 measured under comparable conditions. The [4,4] ion underwent degradation more slowly to the [3,4] ion, which was stable on these time scales. An analogue bearing 4,4′- dimethyl-2,2′-bipyridine ligands exhibited very similar behavior, except that the oxidation steps were shifted by ~50 mV to lower potentials. 18O isotope labeling experiments on the underivatized complex established that there was no oxygen exchange at the bridging mu-oxo position during catalytic turnover. Frozen solutions of the [5,5] ion displayed unusual low-temperature spectroscopic features, including the following: (i) a narrow g = 2.02 axial EPR signal exhibiting an apparent six-line hyperfine interaction from a minor component; (ii) a concentration-dependent broad rhombic EPR signal in mixtures also containing the [4,4] ion; and (iii) a concentration-dependent replacement of its characteristic ruthenyl Ru=O stretching mode at 818 cm-1 in the RR spectrum when chemically oxidized with Ce4+ by an 18O isotope sensitive set of three bands in the 650 cm-1 region. The RR spectrum of this new species is consistent with further coordination of the terminal oxo ligands by Ce4+ to form additional ligand bridges.

A 2,2?:6?,2?-terpyridine bearing a closo-ortho-carboranyl substituent in the 4?-position has been prepared and structurally characterised (triclinic, P 1, a = 6.935(1). b = 12.062(1), c = 13.817(3) A, alpha = 107.827(13), beta = 102.532(13), gamma = 102.222(8), V = 1024.9(3) A3, R = 0.057, Rw = 0.065). Although the free ligand is stable in aprotic solvents, reaction with alcohols leads to the formation of an insoluble Zwitterionic nido-cluster-substituted ligand. A similar nuclearity change occurs upon coordination to ruthenium(II). The presence of a tert-butyldimethylsilyl protecting group on the carborane stabilises the cluster with respect to these nuclearity changes. CNRS-Gauthier-Villars.
