The ligand [2-chloro-3-(3-(2-pyridyl)pyrazolyl)quinoxaline] (L) have been prepared from 2,3-dichloroquinoxaline and 3-(2-pyridyl)-1H-pyrazole. The reaction of N,N?-bidentate chelating ligand (L) and the corresponding metal precursors [(arene)Ru(mu-Cl)Cl]2 {arene = p-cymene, benzene, hexamethylbenzene (HMB)}, [Cp?M(mu-Cl)Cl]2 {Cp? = pentamethylcyclopentadiene; M = Rh, Ir}, [CpRuCl(PPh3)2] {Cp = cyclopentadiene; PPh3 = triphenylphosphine} and [Re(CO)5Br] leads to the formation of mononuclear metal complexes having the general formula [(arene)Ru(L)Cl]+ where, arene = p-cymene (1), C6H6 (2), C6Me6 (3), [Cp?M(L)Cl]+ where, M = Rh (4), Ir (5), [CpRu(L)PPh3]+ (6) and [Re(L)(CO)3Br] (7). All these platinum group metal complexes were synthesized and isolated with PF6 counter anions except complex (6) whereas the complex (7) was isolated as a neutral complex. All these metal complexes were fully characterized by FT-IR, 1H NMR, UV-Vis and mass spectroscopic and analytical techniques. Moreover, the complexes (1-7) were determined by the single-crystal X-ray diffraction analysis. Single crystal X-ray data confirms that the coordination occurs to the N-atoms of the pyridyl and pyrazolyl moieties of the ligand. Agar well diffusion method reveals that complexes (1, 2, 4 and 5) are having good antibacterial activity against the three different bacteria, pathogenic test organisms Staphylococcus aureus subsp. aureus, Staphylococcus epidermidis and Escherichia coli. The electronic transitions and absorption band of the complexes calculated by using time-dependent DFT method are in good agreement with the experimental results.

Application of 246047-72-3, Chemistry can be defined as the study of matter and the changes it undergoes. You’ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology.246047-72-3, Name is (1,3-Bis(2,4,6-trimethylphenyl)-2-imidazolidinylidene)dichloro(phenylmethylene)(tricyclohexylphosphine)ruthenium, molecular formula is C46H65Cl2N2PRu. In a patent, introducing its new discovery.

In this contribution, we study the conversion of a bio-sourced unsaturated fatty ester by cross-metathesis with nitrile-functionalized olefinic partners (acrylonitrile and crotonitrile). A switch from terminal to internal olefins leads to higher conversion. This is in part rationalized by involvement of a more stable ruthenium ethylidene species with crotonitrile. A new carbenic complex forms upon reaction with the nitrile-functionalized olefins, that is also catalytically active.

A chloride anion templation methodology is utilized in the construction of novel transition-metal rhenium(I) and ruthenium(II) bipyridyl appended [2]rotaxanes. 1H NMR spectroscopic titrations reveal the ability of the rotaxanes to selectively bind chloride over the more basic oxoanions, with the ruthenium(II) bipyridyl appended rotaxane strongly binding chloride in 30 % water. Photophysical investigations demonstrate the ability of the rotaxanes to sense anions in aqueous media, with chloride being selectively complexed, in general agreement with NMR spectroscopy determined anion binding data. Chloride anion templation is used to synthesise novel rhenium(I) and ruthenium(II) bipyridyl appended [2]rotaxanes (see figure). 1H NMR spectroscopic titrations reveal the rotaxanes are capable of binding anions in competitive aqueous solvent mixtures, with the ruthenium rotaxane strongly complexing chloride in 30 % water.

Application of 92361-49-4. Let’s face it, organic chemistry can seem difficult to learn. Especially from a beginner’s point of view. Like 92361-49-4, Name is Chloro(pentamethylcyclopentadienyl)bis(triphenylphosphine)ruthenium(II). In a document type is Article, introducing its new discovery.

A synthesis of neutral vinylideneruthenium complexes [RuCl(C=CHR)(PPh3)(eta-C5Me5)] (R = Ph, But or SiMe3) from [RuCl(PPh3)2(eta-C5Me5)] and 1-alkynes has been developed. This takes advantage of the presence of two bulky ligands (PPh3 and C5Me5), which results in displacement of one PPh3 ligand (rather than chloride) and concomitant isomerisation of the 1-alkyne to vinylidene ligands. The vinylidene complexes undergo facile loss of HCl on treatment with NaOMe in the presence of a 2e donor ligand (L) to give the neutral acetyhde complexes [Ru(C?CR)L(PPh3)(eta-C5Me5)] [R = Ph, L = PPh3, CO, O2 or dppm-P; R = But, L = PPh3, CO, C2H4, dppe-P, C2(PPh2)2-P, S2, P(OMe)3 or AsPh3]; the complexes [Ru(C?CBut)(L2)(eta-C5Me5)] [L2 = dppm or PPh2CH= CHPPh2] and [Ru(S2CC?CBut)(PPh3)(eta-C 5Me5)] were also obtained. Crystal structure determinations were carried out on eleven of the complexes.

In a Article，once mentioned of 246047-72-3, Formula: C46H65Cl2N2PRu

The exchange of the PPh3 ligand in the complex [1,3-bis(2,6-dimethylphenyl)4,5-dihydroimidazol-2-ylidene](PPh 3)-(Cl)2Ru=CHPh (7) for a pyridine ligand at ambient temperature leads to the formation of the stable phosphine-free carbene ruthenium complex [1,3-bis(2,6-dimethylphenyl)4,5-dihydroimidazol-2-ylidene] (C5H5N)2(Cl)2 Ru=CHPh (8). The resulted ruthenium complex exhibits highly catalytic activity for the cross metathesis of acrylonitrile with various functionalized olefins under mild conditions, and its activity can be further improved by the addition of a Lewis acid such as Ti(O?Pr)4. In the mixture products, the Z-isomer predominates. The Royal Society of Chemistry 2005.

The compounds [(acac)2RuIII(mu-H2L 2-)RuIII(acac)2] (rac, 1, and meso, 1?) and [(bpy)2RuII(mu-H2L?-) RuII(bpy)2](ClO4)3 (meso, [2](ClO4)3) have been structurally, magnetically, spectroelectrochemically, and computationally characterized (acac- = acetylacetonate, bpy = 2,2?-bipyridine, and H4L = 1,4-diamino-9,10-anthraquinone). The N,O;N?,O?-coordinated mu-H2Ln- forms two beta-ketiminato-type chelate rings, and 1 or 1? are connected via NH···O hydrogen bridges in the crystals. 1 exhibits a complex magnetic behavior, while [2](ClO4)3 is a radical species with mixed ligand/metal-based spin. The combination of redox noninnocent bridge (H 2L0 ? ? ? ?H2L 4-) and {(acac)2RuII} ? ?{(acac) 2RuIV} or {(bpy)2RuII} ? {(bpy)2RuIII} in 1/1? or 2 generates alternatives regarding the oxidation state formulations for the accessible redox states (1n and 2n), which have been assessed by UV-vis-NIR, EPR, and DFT/TD-DFT calculations. The experimental and theoretical studies suggest variable mixing of the frontier orbitals of the metals and the bridge, leading to the following most appropriate oxidation state combinations: [(acac) 2RuIII(mu-H2L?-)Ru III(acac)2]+ (1+) ? [(acac)2RuIII(mu-H2L2-)Ru III(acac)2] (1) ? [(acac)2Ru III(mu-H2L?3-)RuIII(acac) 2]-/[(acac)2RuIII(mu-H 2L2-)RuII(acac)2]- (1-) ? [(acac)2RuIII(mu-H 2L4-)RuIII(acac)2] 2-/[(acac)2RuII(mu-H2L 2-)RuII(acac)2]2- (12-) and [(bpy)2RuIII(mu-H2L?-) RuII(bpy)2]4+ (24+) ? [(bpy)2RuII(mu-H2L?-)Ru II(bpy)2]3+/[(bpy)2Ru II(mu-H2L2-)RuIII(bpy) 2]3+ (23+) ? [(bpy)2Ru II(mu-H2L2-)RuII(bpy) 2]2+ (22+). The favoring of RuIII by sigma-donating acac- and of RuII by the pi-accepting bpy coligands shifts the conceivable valence alternatives accordingly. Similarly, the introduction of the NH donor function in H2L n as compared to O causes a cathodic shift of redox potentials with corresponding consequences for the valence structure.
