N-heterocyclic carbene complexes of ruthenium(II), [CpRu(L*)2Cl] (2) and [CpRu(CO)(L*)-Cl] (3) (Cp = eta5-C5H5; L* = l,3-dicyclohexyl-imidazolin-2-ylidene), have been obtained in high yields by reaction of [CpRu(PR2R?)2Cl] (R = R? = Ph, la; R = Ph, R? = 2-MeC6H4, 1b) and [CpRu(CO){PPh2(2-MeC6H4)}Cl] (1c), respectively, with the free carbene L*. The mixed dicarbene complex [CpRu(=CPh2)(L*)Cl] (4) is prepared from [CpRu(=CPh2){PPh2(2-MeC6H4-Cl] (1d) and an equimolar amount of L*, whereas subsequent reaction of 1d with L* leads to formation of 2, along with tetraphenylethene. The reaction of [Cp*Ru(PPh3)2Cl] (1e) with L* gives the pentamethylcyclopentadienyl derivative [Cp*Ru(PPh3)(L*)Cl] (5) (Cp* = eta5-C5Me5) by displacement of 1 equiv of PPh3 Complex 5 reacts in toluene with CO, pyridine (Py), and N2CHCO2Et, affording [Cp*Ru(CO)(L*)Cl] (6), [Cp*Ru(Py)(L*)Cl] (7), and the mixed dicarbene [Cp*Ru(=CHCO2Et)(L*)Cl] (8), which were isolated in high yields. The molecular structure of complex 6 has been determined by an X-ray investigation, and the carbene-ruthenium distance clearly indicates a single bond (2.0951(18) A). The N-heterocyclic carbene does not undergo substitution by other two-electron ligands.

A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 37366-09-9, Name is Dichloro(benzene)ruthenium(II) dimer, molecular formula is C12H12Cl4Ru2. In a Article，once mentioned of 37366-09-9, Computed Properties of C12H12Cl4Ru2

In this article, Ru(ii)-arene-2-pyridinylbenzoxazole complexes [(eta6-p-cymene)RuCl(kappa2-N,N-5-bromo-2-(pyridine-2-yl)benzo[d]oxazole)] (4) and [(eta6-benzene)RuCl(kappa2-N,N-5-bromo-2-(pyridine-2-yl)benzo[d]oxazole)] (5) and Ru(ii)-arene-2-quinolylbenzoxazole complexes [(eta6-p-cymene)RuCl(kappa2-N,N-5-bromo-2-(quinoline-2-yl)benzo[d]oxazole)] (4?) and [(eta6-benzene)RuCl(kappa2-N,N-5-bromo-2-(quinoline-2-yl)benzo[d]oxazole)] (5?) were synthesized and characterized using various spectroscopic techniques. Structural analysis indicates that the Ru(ii) centres are in a distinct mononuclear, one-sided octahedral [RuN6] coordination geometry with two neutral bidentate nitrogen donors in the bromobenzoxazole ligands. All four complexes exhibit three different electronic bands: a sharp band at 300-330 nm due to ligand-to-ligand charge transfer (LLCT); a band around 400 nm due to metal-to-ligand charge transfer; and a small broad peak at around 600 nm due to ligand-to-metal charge transfer. The fluorescence abilities of the four complexes were studied using the LLCT absorption peak as the excitation energy in dimethylsulfoxide: water (1?:?1, v/v), and the quantum yield was found to decrease in the order of 5? > 4? > 4 > 5. Density functional theory calculations reveal that the highest-occupied molecular orbital is primarily located on the benzoxazole ring system, while the lowest-unoccupied molecular orbital is mainly located on the Ru atom, which implies possible charge transfer from ligand to metal. The binding strengths of the Ru(ii) complexes with DNA (5? > 4? > 4 > 5) and bovine serum albumin (4? > 5? > 5 > 4) were on the order of 105-106 and 103-105 M?1, respectively. The conductometric data reveal that all four complexes are non-electrolytic in nature, and viscosity decreases in the order of 5? > 4? > 4 > 5. This might be due to the effective intercalation of 5? compared to the other complexes. DNA and protein docking studies suggest that all the complexes interact with DNA through the minor groove and favourably occupy the active sites of proteins based on dipole-dipole interactions. Gel electrophoresis studies show that all complexes degrade plasmid DNA (1 kb) completely within 1 h of exposure time. MTT assay results indicate that all complexes exhibit highly selective cytotoxicity for two cancer cell lines (Caco-2 and HeLa) with respect to normal HEK-293 cells. Among the complexes, 4? and 5 show the highest cytoselectivities for the Caco-2 and HeLa cell lines, respectively.

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.

Rationally designed RuO2-based Deacon catalysts can contribute to massive energy saving compared to the current electrolysis process in chemically recycling HCl to produce molecular chlorine. Here, we report on our integrated approach between state-of-the-art experiments and calculations. The aim is to understand industrial Deacon catalyst in its realistic surface state and to derive mechanistic insights into this sustainable reaction. We show that the practically relevant RuO2/SnO2 consists of two major RuO2 morphologies, namely 2-4 nm-sized particles and 1-3-ML-thick epitaxial RuO2 films attached to the SnO2 support particles. A large fraction of the small nanoparticles expose {1 1 0} and {1 0 1} facets, whereas the film grows with the same orientations, due to the preferential surface orientation of the rutile-type support. Steady-state Deacon kinetics indicate a medium-to-strong positive effect of the partial pressures of reactants and deep inhibition by both water and chlorine products. Temporal Analysis of Products and in situ Prompt Gamma Activation Analysis strongly suggest a Langmuir-Hinshelwood mechanism and that adsorbed Cl poisons the surface. Under relevant operation conditions, the reactivity is proportional to the coverage of a specific atomic oxygen species. On the extensively chlorinated surface that can be described as surface oxy-chloride, oxygen activation is the rate-determining step. DFT-based micro-kinetic modeling reproduced all experimental observations and additionally suggested that the reaction is structure sensitive. Out of the investigated models, the 2 ML RuO2 film-covered SnO2 gives rise to significantly higher reactivity than the (1 0 1) surface, whereas the 1 ML film seems to be inactive.

The stereoselective syntheses of synargentolide B and its three stereoisomers have been accomplished from L-(+)- and D-(-)-diethyl tartrates, D-ribose, and D-mannitol as chiral pool starting materials. The key step was a tandem ring-closing/cross-metathesis reaction in which lactone formation and fragment coupling were accomplished in one pot. The spectroscopic data of synthetic product 2c were in agreement with those reported for the natural product. Synargentolide B isolated by Rivett et al. and the compound isolated by Pereda-Miranda et al. are not diastereomers, but rather they are identical. Copyright

A document type is Article, introducing its new discovery.

Half-sandwich ruthenium(II) PTA complexes bearing the 1,2-dihydropentalenyl (C8H9-, Dp) and indenyl (C9H 7-, Ind) ancillary ligands have been synthesized and characterized using multinuclear NMR spectroscopy and X-ray crystallography. The complexes DpRu(PTA)(PPh3)Cl, DpRu(PTA)2Cl, IndRu-(PTA)(PPh3)Cl, and [IndRu(PTA)2(PPh3)]CI were obtained in good to excellent yields. The solid-state structures of these compounds exhibit piano stool geometries with eta5-coordination of the indenyl and dihydropentalenyl moieties. DpRu(PTA)2Cl is water-soluble (S25C = 43 mg/mL), while the mixed phosphine compounds are slightly soluble in acidic solutions. The Ru-H complexes, Cp?Ru(PTA)(PPh3)H (Cp? = Ind, Cp), have been synthesized in good yield and spectroscopically and structurally characterized. The ruthenium hydrides undergo an H/D exchange reaction with CD3OD with relative rates CpRu(PTA)-(PPh3)H ? IndRu(PTA)(PPh3)H > CpRu(PTA)2H. The air-stable Cp?Ru(PTA)(PR3)Cl complexes (Cp? = Cp, Dp, Ind; PR3 = PPh3 or PTA) exhibit activity in the regioselective transfer hydrogenation of alpha,beta-unsaturated carbonyls in aqueous media with HCOONa, HCOOH, or isopropanol/Na2CO3 serving as the hydrogen source. They were found to be effective in the selective reduction of the carbonyl functionality of cinnamaldehyde and the C=C bond of benzylidene acetone and chalcone. IndRu(PTA)(PPh3)Cl was less active than Cp?Ru(PTA)(PPh3)Cl (Cp? = Cp or Dp). Results of the transfer hydrogenation of unsaturated substrates using CpRu(PTA)(PPh 3)H are also reported.

Related Products of 246047-72-3, An article , which mentions 246047-72-3, molecular formula is C46H65Cl2N2PRu. The compound – (1,3-Bis(2,4,6-trimethylphenyl)-2-imidazolidinylidene)dichloro(phenylmethylene)(tricyclohexylphosphine)ruthenium played an important role in people’s production and life.

The first total synthesis of the marine dolabellane diterpene (+)-4,5-deoxyneodolabelline (1) has been accomplished. The highly efficient approach is characterized by the convergent assembly of dihydropyrans 2ab and cyclopentylsilanes 3ab. Allylic silane 3a was prepared from 2- methyl-2-cyclopentenone via a copper-catalyzed 1,4-addition followed by diastereoselective alkylation of the resulting enolate. A chemical resolution of racemic cyclopentanone 8 was effected by (S)-CBS-catalyzed borohydride reduction. Direct hydroxymethylation of the enantioenriched ketone 8 to form allylic alcohol 14 was achieved by a Stille palladium-catalyzed cross-coupling from the cyclopentenyl triflate 13. Treatment of the corresponding allylic phosphate 15 with trimethylsilylcopper reagent provided for displacement with allylic transposition yielding the exocyclic allylsilane 3a with excellent diastereoselectivity. Dihydropyrans 2a and 2b were prepared from optically pure acyclic acetals via ring-closing metathesis. Coupling of 3a and 2a or 2b via the carbon-Ferrier protocol gave trans-2,6-disubstituted dihydropyrans 30 and 35 with complete stereoselectivity. Vanadium-based pinacol coupling reactions were explored for closure of the mediumsized carbocycle to yield syn-diol 33. X-ray diffraction studies of the monobenzoate 34 have provided unambiguous stereochemical assignments. Substantial ring strain accounted for the lack of alkene products typical of reductive elimination using TiCl3 and zinc-copper couple (McMurry) conditions leading to 37. Finally, the natural product 1 was obtained via Swern oxidation of the diol 37.
