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, COA of Formula: C12H12Cl4Ru2

Cyclopentadienide derivatives possessing intrinsic helical chirality have only rarely been published in the past. The ligand CpCH, which is well-accessible from inexpensive dibenzosuberenone, is paradigm for such a ligand. Here, the synthesis as well as the spectroscopic and structural characterization of a series of platinum group metal complexes containing this ligand are presented. While alkaline metal salts of CpCH failed in transferring the (CpC)-1 unit to this type of metal sites, (CpC)Tl turned out to be an excellent precursor for the synthesis of ruthenium ([(eta5-CpC)Ru(eta6-arene)]PF6, [(eta5-CpC)Ru(NCCH3)3)]PF6), rhodium ((eta5-CpC)Rh(eta4-COD)), and iridium ((eta5-CpC)Ir(eta4-COD), [(eta5-Cp*)Ir(eta5-CpC)]PF6) complexes with CpC ligands. EXSY NMR studies were carried out to obtain a deeper insight into the ligand dynamics of CpC complexes.

Enantioselective reduction of prochiral ketones to optically active secondary alcohols is an important subject in synthetic organic chemistry because the resulting chiral alcohols are extremely useful, biologically active compounds. The new chiral ligands (2R)-2-[benzyl{(2-((diphenylphosphanyl)oxy) ethyl)}amino]butyldiphenylphosphinite, 1 and (2R)-2-[benzyl{(2- ((dicyclohexylphosphanyl)oxy)ethyl)}amino]butyldicyclohexylphosphinite, 2 and the corresponding ruthenium(II) complexes 3 and 4 have been prepared. The structures of these complexes have been elucidated by a combination of multinuclear NMR spectroscopy, IR spectroscopy and elemental analysis. 31P-{1H} NMR, DEPT, 1H-13C HETCOR or 1H-1H COSY correlation experiments were used to confirm the spectral assignments. These ruthenium(II)-phosphinite complexes have been used as catalysts for the asymmetric transfer hydrogenation of acetophenone derivatives. Under optimized conditions, aromatic ketones were reduced in good conversions and in moderate to good enantioselectivities (up to 85% ee).

Application of 32993-05-8, An article , which mentions 32993-05-8, molecular formula is C41H35ClP2Ru. The compound – Chlorocyclopentadienylbis(triphenylphosphine)ruthenium(II) played an important role in people’s production and life.

[CpRu(dppf)Cl] (Cp=eta5-C5H5) (1) and [(HMB)Ru(dppf)Cl]PF6 ((HMB)=eta6-C6Me6) (3) react with different donor ligands to give rise to N-, P- and S-bonded complexes. The stoichiometric reactions of 1 and 3 with NaNCS give the mononuclear complexes [CpRu(dppf)(NCS)] (2) and [(HMB)Ru(dppf)(NCS)]PF6 (4), respectively, in yields above 80%, while 3 also gives a dppf-bridged diruthenium complex [(HMB)Ru(NCS)2]2 (mu-dppf) (5) in 67% yield from reaction with four molar equivalents of NaNCS. Compound 5 is also obtained in 70% yield from the reaction of 4 with excess NaNCS. With CH3CN in the presence of salts, both 1 and 3 give their analogous solvento derivatives [CpRu(dppf) (CH3CN)] BPh4 (6) and [(HMB)Ru(dppf) (CH3CN)] (PF6)2 (7). With phosphines, the reaction of 1 gives chloro-displaced complexes [(CpRu(dppf)L]PF6 (L =PMe3 (8), PMe2Ph(9), whereas the reaction of 3 with PMe2Ph leads to substitution of dppf, giving [(HMB)Ru(PMe2Ph)2Cl] PF6 (10). The reaction of 1 with NaS2CNEt2 gives a dinuclear dppf-bridged complex [{CpRu(S2CNEt2)} 2(mu-dppf)] (11), whereas that of 3 results in loss of the HMB ligand giving a mononuclear complex [Ru(dppf) (S2CNEt2)2] (12). With elemental sulfur S8, 1 is oxidized to give a dinuclear CpRuIII dppf-chelated complex [{CpRu(dppf)}2(mu-S2)] (BPh4)Cl (13), whereas 3 undergoes oxidation at the ligand, giving a dppf-displaced complex [(HMB)Ru(CH3CN)2Cl] PF6 (14) and free dppfS2. The structures of 1, 2, 5-9, 11, 13 and 14 were established by X-ray single crystal diffraction analyses. Of these, 5 and 11 both contain a dppf-bridge between RuII centers, while 13 is a dinuclear CpRuIII disulfide-bridged complex; all the others are mononuclear. All complexes obtained were also spectroscopically characterized.

Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments.Introducing a new discovery about 37366-09-9, Name is Dichloro(benzene)ruthenium(II) dimer, name: Dichloro(benzene)ruthenium(II) dimer.

New ruthenium(II) arene derivatives (arene = p-cymene, benzene, hexamethylbenzene) containing beta-ketoamine ligands L? (HL? in general; in detail, HLph,ph = (4Z)-3-methyl-4-((phenylamino)(phenyl) methylene)-1-phenyl-1H-pyrazol-5(4H)-one, HLnaph,ph = (4Z)-3-methyl-4-((phenyamino)(naphthalen-2-yl)methylene)-1-phenyl-1H-pyrazol- 5(4H)-one, HLet,ph = (4Z)-3-methyl-4-(1-(phenylamino)propylidene)-1- phenyl-1H-pyrazol-5(4H)-one) have been synthesized and characterized by spectroscopy (IR, ESI-MS, 1H and 13C NMR) and elemental analysis. The ligands in the anionic form coordinate ruthenium in a chelating kappa2N,O-bidentate fashion, affording 1:1 derivatives of the formula [Ru(arene)(L?)Cl]. Further reaction of [Ru(p-cymene)(L?)Cl] with AgPF6 or PTA (PTA = 1,3,5-triaza-7-phosphaadamantane) in methanol affords [Ru(p-cymene)(L?)(CH3OH)][PF6] and [Ru(p-cymene)(L?)(PTA)]Cl, respectively. The solid-state structures of the ligand HLet,ph and complexes [Ru(p-cymene)(Lph,ph)Cl] (1), [Ru(p-cymene)(Lnaph,ph)Cl] (4), and [Ru(p-cymene)(L et,ph)Cl] (7) have been determined by single-crystal X-ray diffraction. The antitumor activity of both the ligands and complexes has been evaluated against the human ovarian carcinoma cell line A2780 and its cisplatin-resistant equivalent A2780R, some of the complexes showing significant cytotoxicity toward the cisplatin-resistant cell line.

Synthetic Route 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 DSA anodes based on RuO2-SnO2 oxides are most employed in chlorine-alkali cells. Their properties are strongly influenced by the mixed-oxide coating structures. In this paper, two RuO2-SnO2/Ti DSA anodes with different Ru and Sn molar ratios were prepared through a sol-gel technique. The nano-structure, morphology, grain structure and composition of the coatings were investigated by means of XRD, SEM and TEM. XRD analysis indicates two rutile-type solid solutions are formed. Peak profile analysis shows that in the solid solution where SnO2 is the major component smaller crystallites (about 20-30 nm) are formed than in those where RuO2 is the major component (about 100-200 nm). The SEM images reveal the coating with high level of SnO2 possesses more accumulated and compact structures. The EDS analysis indicates that two DSA anodes coatings in which SnO2 is similar to the designed concentration are prepared by the sol-gel method. TEM characterization shows the polygonal crystallites are present in the obtained RuO2-SnO2 coatings. The voltages of Cl2-evolution and O2-evolution suggest both RuO2-SnO2/Ti DSA anodes have a good electrochemical performance and can be used for the chlorite industrial productions.

A route for the synthesis of coordinatively dissymmetrical iron(II) polypyridine complexes [Fe(L)2L’]2+ (L and L’ are two different 2,2′- bipyridine derivatives) is described. The procedure is based on the use of the precursor [Fe(L)2(CH3CN)2]2+ (L = 2,2′-bipyridine), which can be easily prepared by electrochemical or chemical reduction of the mu-oxo diaqua diiron(III) complex [Fe2O(bpy)4(H2O)2]4+ in acidic CH3CN solution. In addition, it is shown that this procedure can be applied with success to the synthesis of covalently linked heterodinuclear complexes containing, for instance, Fe(bpy)32+ and Ru(bpy)32+ moieties. The electrochemical behaviour of all these new complexes is reported.

anti-Configured 1,3-dimethyl deoxypropionate motifs are important sub structures in natural products. Herein, we describe a bidirectional approach for the rapid construction of natural products featuring such motifs by using C2-symmetrical 1,3-bis(boronic esters). As for its application in convergent syntheses it was important to establish a selective mono-Zweifel olefination we describe the scope and limitations by using different 1,3-bis(boronic esters) and nucleophiles. This protocol takes advantage of the combination of the Hoppe?Matteson?Zweifel chemistry, which was elegantly put into practice by Aggarwal et al. In order to show its applicability the total syntheses of two natural products, serricornin and (+)-invictolide, were performed.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 114615-82-6 is helpful to your research., Synthetic Route of 114615-82-6

Allyl thioether complexes [CpRu(P-P)(SRR?)]PF6 (P-P = Ph2PCH2PPh2 (dppm), Ph2PC2H4PPh2 (dppe), R = Me, Et, Ph, R? = 3-propenyl, 3-cyclohexenyl, 2-methyl-2-buten4-yl) and [CpRu(chir)(SRR?)]PF6 (chir = (S,S)-Ph2PCHMeCHMePPh2, R = Me, CH2Ph, R? = 2-methyl-2-buten-4-yl) are obtained from the corresponding thiolate complexes by reaction with the appropriate allyl bromide. Careful oxidation with dimethyldioxirane (DMD) gave the allyl sulfoxide complexes [CpRu(P-P)(MeS(O)CH2CH=CH2)]PF6 (P-P = dppm, dppe). Double oxidation to the corresponding sulfinylmethyl epoxide complexes can be readily achieved with an excess of DMD. Oxidation of the chir complexes proceeds with only moderate diastereoselectivity. The structure of the (R, R/S, S) diastereomer of [CpRu(dppm)(MeS(O)CH2CHCH2O)]PF6 was determined: monoclinic space group P21/c (No. 14), a = 11.21(2), b = 16.762(9), c = 18.45(4) A, beta = 94.4(1), Z = 4. For a representative example, the decomplexation of the sulfoxide-epoxide ligand by sodium iodide in acetone was demonstrated.

Complex 6 is less soluble in common organic solvents than the other complexes but this insolubility has been overcome by introducing a methylcyclopentadienyl group on the ruthenium centre to form complex 7. Complexes 1, 2, 4, 6 and 7 have shown reversible redox chemistry and in the di-metallic complexes, intramolecular electronic communication has been investigated by cyclic voltammetry. The shift in the lowest energy band in the UV-vis spectra of the mixed-metal complexes 4, 5, 6 and 7 is largely dependent on the various metal fragments.
