Two concise syntheses of the natural products cis-sylvaticin and sylvaticin are reported, using oxidative cyclization methodology as the key step. A sequential solvolysis/hydride shift/intramolecular reduction cascade was used to establish the trans stereochemistry of one of the THF rings of sylvaticin.

Allyl sulfides undergo efficient cross-metathesis in aqueous media with Hoveyda-Grubbs second generation catalyst 1. The high reactivity of allyl sulfides in cross-metathesis was exploited in the first examples of cross-metathesis on a protein surface. S-Allylcysteine was incorporated chemically into the protein, providing the requisite allyl sulfide handle. Preliminary efforts to genetically incorporate S-allylcysteine into proteins are also reported. Copyright

The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.15746-57-3, Name is Cis-Dichlorobis(2,2′-bipyridine)ruthenium(II), molecular formula is C20H16Cl2N4Ru. In a Article，once mentioned of 15746-57-3, category: ruthenium-catalysts

Ru(bpy)32+ (bpy = 2,2′-bipyridyl) has been covalently attached to n-type SnO2 via condensation of surface hydroxyl groups with ruthenium (4-(trichlorosilylethyl)-4′-methyl-2,2′-bipyridine)bis(2,2′-bipyridine) bis(hexafluorophosphate)).A thick coating (ca. 1000 layers, based on the surface hydroxyl group concentration) was produced, presumably via oligomerization of hydrolyzed -SiCl3 groups.The coating, which was stable to organic solvents as well as to aqueous acids and bases, gave reversible cyclic voltammograms, with peak potentials shifted slightly from those of aqueous Ru(bpy)32+, but the number of electroactive molecules corresponding only to a few layers.The coated electrode gave a photocurrent about twice that observed for SnO2 in contact with aqueous 4mM Ru(bpy)32+, with a slightly red-shifted excitation spectrum.Only a small fraction of the electroactive molecules appeared to participate in excited-state electron transfer, although a steady-state current was supported, presumably by slow electron transfer from the outer layers.Prolonged illumination produces extensive hydrolysis of the outer layers of the coating, but a modest reduction of electroactivity, and only a slight decrease in photocurrent.The photocurrent increases with applied potential, then reaches a plateau, and falls off again near the reduction potential of Ru(bpy)32+*; the falloff is attributed to back-electron transfer via tunnelling through the thin space charge layer.

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.category: ruthenium-catalysts, you can also check out more blogs about15746-57-3

Reference of 10049-08-8, An article , which mentions 10049-08-8, molecular formula is Cl3Ru. The compound – Ruthenium(III) chloride played an important role in people’s production and life.

The kinetics of ruthenium(III) catalyzed oxidation of L-proline by diperiodatocuprate(III) (DPC) in alkaline medium at constant ionic strength (0.10 mol dm-3) has been studied spectrophotometrically using a rapid kinetic accessory. The reaction showed first order kinetics in [DPC] and [RuIII] and apparently less than unit order dependence each in L-proline and alkali concentrations. A mechanism involving the formation of a complex between the L-proline and the hydroxylated species of ruthenium (III) has been proposed. The active species of oxidant and catalyst were [Cu(OH) 2 (H3IO6)2 (H2IO 6)2]4- and [Ru (H2O) 5OH]2+ respectively. The reaction constants involved in the mechanism were evaluated. The activation parameters were computed with respect to the slow step of the mechanism and discussed. Nauka/Interperiodica 2006.

Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments.Introducing a new discovery about 10049-08-8, Name is Ruthenium(III) chloride, Product Details of 10049-08-8.

A theoretical study of the ruthenium(III) complex [RuCl2(pz2CHSO3)(en)] and of its nitrosyl-substituted product [Ru(NO)Cl(pz2CHSO3)(en)]+ is presented, based on density functional calculations. Several isomers of each compound differing in the position of the anionic tail of a bis(3,4-dimethyl-1-yl)methanesulfonate scorpionate ligand, pz2CHSO3-, relative to the monodentate ligands have been optimized. A two-step mechanism is proposed for the ligand substitution reaction that is consistent with the computational results and the weak coordination of the sulfonate group.

Children learn through play, and they learn more than adults might expect. Science experiments are a great way to spark their curiosity, get their minds active, and encourage them to do something that doesn’t involve a screen. 10049-08-8, Cl3Ru. A document type is Article, introducing its new discovery., Quality Control of: Ruthenium(III) chloride

The hydrogen adsorption properties and uptake capacities of NaX and its palladium and ruthenium exchanged forms were investigated at 77 K in a static volumetric adsorption setup up to 1 bar, and at 303 K and 333 K in a gravimetric adsorption system up to 5 bar. All the hydrogen adsorption isotherms were of Type I with a maximum adsorption capacity shown in NaX at 77 K temperature. Hydrogen adsorption capacities at 77 K were found to be decreasing as palladium and ruthenium exchange levels increases. Chemisorption of hydrogen was observed at 303 K and 333 K and was due to the chemical interaction between the transition metal cations and the hydrogen molecules. The maximum hydrogen uptake at 303 K and 5 bar was observed for palladium exchanged zeolite X with a value of around 85 cm3/g. Grand canonical Monte Carlo simulations were also performed to study the adsorption of H2 in these zeolites at 77 K as well as 303 K and 333 K. The simulation studies are suitable for establishing a correlation between the microscopic behavior of the zeolite and adsorbate system with the macroscopic properties which are measured experimentally, such as adsorption isotherms.

The invention provides a method for preparing nitrile compounds through ruthenium metal complex catalytic primary amine dehydrogenation, and belongs to the technical field of energy and homogeneous catalysis. The invention successfully designs a series of ruthenium metal complex catalysts, and can efficiently catalyze the dehydrogenation of primary amine compounds to prepare nitrile compounds. The catalyst has the advantages of simple preparation method, good stability, high selectivity and wide substrate applicability. Taking benzylamine dehydrogenation to give a nitrile as an example, the yield of benzonitrile can reach unitz 95%. This reaction does not need to use highly toxic cyanogen reagent and strong oxidant, has avoided causing the pollution to the environment, has also eliminated the potential safety hazard. The only by-product of this catalytic reaction is hydrogen, and it both can regard as green energy, also can regard as the hydrogen source of other reaction. In addition, the realization of the catalytic reaction also provides an idea for the amine substances as the liquid hydrogen storage material. (by machine translation)

A series of functionalized polynorbornenes containing pendent ether- or ester-bridged poly(aromatic ether) chains were prepared. The ether-bridged norbornene complex was synthesized via cyclopentadienyliron-mediated nucleophilic aromatic substitution reactions. This methodology, combined with that of dicyclohexylcarbodiimidemediated coupling, allowed for the formation of novel oligomeric aryl ether and ester substituted norbornene complexes. Photolytic demetallation gave the monomers in good yields. Structural identification of the exo and endo isomers of both the metallated and demetallated norbornene derivatives was accomplished using HH and CH COSY NMR techniques. Ring-opening metathesis polymerization (ROMP) of these monomers using RuCl3(hydrate) and (Cy3P)2Cl2Ru=CHPh allowed for the preparation of the functionalized polynorbornenes. Thermal analysis of the resulting polymeric materials demonstrated greater thermal stability as the number of aryl ether groups increased.
