We report the use of RuCl3 as an “alkali metal sponge”. This is a general and highly efficient method for generating protonated parent ions for a variety of compounds that usually do not show this ion in electrospray mass spectrometry. This technique is demonstrated to be highly useful in “cleaning up” spectra from multiply metallated ions, thereby substantially improving the signal-to-noise ratio.

The half-sandwich Ru(II) complexes of the type [CpRu(PPh2 N(H)R)(PPh3)Cl], [CpRu(PPh2N(H)R)2Cl] (R=Ph, C6H11) and [CpRu(PPh2N(R?) PPh2-kappaP,kappaP)(PPh3)]Cl (R?=Et, nPr, iPr, nBu), were synthesized and the structures of complexes [CpRu(PPh2N(H)Ph)(PPh3) Cl] and [CpRu(PPh2N(H)Ph)2Cl] were confirmed by single crystal X-ray diffraction studies. All ruthenium complexes were employed in the cyclopropanation reaction of styrene derivatives in the presence of diphenyldiazomethane. All complexes afford 1,1,3,3-tetraphenyl cyclobutane along with cyclopropane derivatives; complex, [CpRu(PPh2N(nBu)PPh2-kappa P,kappaP) (PPh3)]Cl shows better selectivity in the formation of 1,1,2-triphenylcyclopropane. In all reactions appreciable amounts of cyclopropanation products and metathesis products, 1,2-diphenylcyclopropane and 1,1-diphenylethene were obtained along with 1,1,3-triphenylpropene derivatives. The variable temperature NMR studies have suggested that the cyclopropanation reactions in the presence of ionic complex, [CpRu(PPh2N(R?)PPh 2-kappaP,kappaP)(PPh3)]Cl proceeds via carbene intermediate, [CpRu(=CPh2)(PPh2N(R?) PPh2-kappaP)(PPh3)]Cl.

The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.246047-72-3, Name is (1,3-Bis(2,4,6-trimethylphenyl)-2-imidazolidinylidene)dichloro(phenylmethylene)(tricyclohexylphosphine)ruthenium, molecular formula is C46H65Cl2N2PRu.

Cadmium selenide nanoparticles, prepared by known methods, were stabilized with functional phosphine oxide 1, then used to support the polymerization of cyclic olefins radially outward from the surface by ruthenium-catalyzed ring-opening metathesis polymerization (ROMP). The conversion of compound 1 into the new metathesis catalyst 3 by carbene exchange and the subsequent polymerization of cyclic olefins were observed spectroscopically by 1H NMR to afford for example CdSe-polycyclooctene composite 6. Transmission electron micrographs on thin films of these composites showed good nanoparticle dispersion. This is in stark contrast to the substantial nanoparticle aggregation observed when similar polymerizations were performed in the presence of conventional TOPO-covered nanoparticles. The methods reported here to prepare composite product 6 are applicable to other cyclic olefins, and suggest that this chemistry will be useful for incorporating CdSe nanoparticles into a wide variety of polymer matrices.

New copper and ruthenium mononuclear complexes of the type [ML 2(H2O)X] [X = H2O for M = Cu(II) and X = Cl for M = Ru(III)] have been prepared from 1-p-diphenyl- methane-2-hydroxyimino-2-(4- chloroanilino)-1-ethanone (HL1) and 1-p-diphenylmethane-2- hydroxyimino-2-(4-toluidino)-1-etha- none (HL2). The complexes were characterized by elemental analyses, magnetic susceptibility, molar conductance, IR, thermal analysis, and cyclic voltammetry. Stoichiometric and spectral results of the metal complexes indicated that the metal:ligand ratios in the complexes were found to be 1:2 and the ligands behave as a bidentate ligand forming neutral metal chelates through the carbonyl and oxime oxygen. The electrochemical behavior of the ligands and their complexes were obtained by cyclic voltammetry. The interaction between these complexes with DNA has also been investigated by agarose gel electrophoresis. The copper(II) complexes (3 and 4) with H2O2 as a co-oxidant exhibited strongest cleaving activity. Moreover, catalytic activities of the complexes for the disproportionation of hydrogen peroxide were also investigated in the presence of imidazole.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.Formula: Cl3H2ORu, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 20759-14-2, in my other articles.

Children learn through play, and they learn more than adults might expect.

A document type is Article, introducing its new discovery., Computed Properties of C41H35ClP2Ru

A series of ruthenium(II) complexes have been prepared by using bidentate chelating N-heterocyclic carbene (NHC) ligands that feature different donor groups E (E = olefin, thioether, carboxylate, and NHC). Rigid coordination of all donor sites was concluded from NMR spectroscopy, and the electronic impact of the donor group was evaluated by electrochemical analyses. The chelating donor group had a strong influence on the activity of the metal center in catalyzing direct hydrogenation of styrene. A thioether group or a second NHC donor site essentially deactivates the metal center. Complexes comprising a NHC tethered with an olefin or a carboxylate group showed appreciable activity, though only the carboxylate-functionalized system proved to be a precursor for homogeneous hydrogenation. According to in situ high-pressure NMR analyses, complexes featuring a carboxylate chelating group are remarkably resistant toward reductive elimination even under strongly reducing conditions and may, therefore, be used repeatedly

Application of 301224-40-8, Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. 301224-40-8, Name is (1,3-Dimesitylimidazolidin-2-ylidene)(2-isopropoxybenzylidene)ruthenium(VI) chloride, molecular formula is C31H38Cl2N2ORu. In a Article，once mentioned of 301224-40-8

The investigations disclosed offer insight regarding several key features of Ru-based catecholthiolate olefin metathesis catalysts. Factors influencing the facility with which the two anionic ligands undergo exchange and those that affect the rates of catalyst release are elucidated by examination of more than a dozen new complexes. These studies shed light on how different chelating groups can influence Ru-S bond strength and, as a result, the facility of catecholthiolate rotation. The trans influence series ether < ester ? iodide < amine ? thioether ? olefin < isonitrile ? phosphite has been established through X-ray structural analysis and shown to correlate well with the barrier for catecholthiolate rotation (trans effect) determined by variable-temperature NMR experiments and computational studies (DFT). It is found that, apart from electronic factors, chelate geometry has a more notable effect on the rate of catalyst release (five- vs six-membered chelate ring and mono- vs bidentate ligand). Polytopal processes involving pentacoordinate Ru(II) carbene complexes are shown to be distinct from previously reported fluxional events that involve tetracoordinate species and which are capable of causing diminished polymer syndiotacticity. Ru mercaptophenolate complexes have been synthesized and isolated as a single diastereomer (O-C trans to the NHC). This latter set of species promotes representative olefin metathesis reactions readily and gives Z selectivity levels that are higher than those when the corresponding catecholate systems are used, but less so in comparison to catecholthiolate complexes. A rationale for variations in stereoselectivity is presented. The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant.
