A process has been invented for the oxygenation of cyclic ethers. General problems in the process are the use of expensive and toxic oxidants, low TONs (turnover numbers), low selectivity and working at elevated temperatures (energy costs). These problems were solved by employing appropriate organometallic catalyst precursors. Using lnd(CO)3Mo-Ru(CO)2Cp, Cp(CO)3Mo-Ru(CO)2Cp and Cp(CO)2Ru-Ru(CO)2Cp or other ruthenium compounds, the aerobic oxidation of tetrahydrofurane (THF) proceeds at room temperature and produces selectively gamma-butyrolactone. Use of the catalysts yields replacement of stoichiometric, toxic co-oxidants by cheap air oxygen, working at room temperature, high selectivity, high TONs and overall formulation of green chemistry which is applicable to cyclic ethers: formula (I) The invented process satisfies the urge for green chemistry by using cheap air oxygen in a catalytic process with unlimited catalyst lifetime and plain water as the side product. Functionalised lactones will be available from corresponding ethers.

A triphenylphosphinegold(I)-catalyzed cyclopropanation of olefins using propargyl esters as gold(I)-carbene precursors is reported. This reaction provided the basis for the use of a DTBM-SEGPHOS gold(I) complex as a catalyst in the enantioselective (up to 94% ee) preparation of vinyl cyclopropanes with high cis-selectivity.

The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.10049-08-8, Name is Ruthenium(III) chloride, molecular formula is Cl3Ru. In a Article，once mentioned of 10049-08-8, HPLC of Formula: Cl3Ru

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.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.HPLC of Formula: Cl3Ru, you can also check out more blogs about10049-08-8

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.

Dye-sensitized photo-electrochemical cells based on a solid poly-(3,4-(ethylenedioxy)pyrrole) (PEDOP) electron mediating matrix were assembled and photo-electrochemically characterized. The conductive polymer was directly grown on the sensitized TiO2 surface exploiting a photo-assisted electropolymerization promoted by a properly designed ruthenium dye bearing pyrrole functionalities. J-V characteristics and photoaction spectra indicated very low efficiencies mainly determined by an efficient recombination of photo-injected electrons with both PEDOP acceptor states and oxidized sensitizers.

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
