Reference of 37366-09-9, 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.37366-09-9, Name is Dichloro(benzene)ruthenium(II) dimer, molecular formula is C12H12Cl4Ru2. In a patent, introducing its new discovery.

We present a C-H activation protocol for aromatic compounds that overcomes the current limitations of the need for a directing group or covalently bound activating groups, by exploiting the increase in C-H acidity of aromatic compounds on pi-coordination to a Ru(II) center. The increased acidity facilitates catalytic concerted metalation-deprotonation and subsequent arylation reactions. We present the development and optimization of the C-H activation protocol and show the applicability of the reaction to a range of aromatic substrates, including the simplest of substrates (benzene). Furthermore, we demonstrate the recyclability of the activating Ru(II) fragment using photolysis and give a mechanistic study, which provides strong evidence that this reaction occurs via a silver-mediated C-H bond activation. This is the first time Ru complexes have been shown to allow C-H activation of arenes by a pi-coordination mechanism.

The cationic chloro complexes [(arene)Ru(H2N?NH 2)Cl]+ (1: arene = C6H6; 2: arene = p-MeC6H4iPr; 3: arene = C6Me6) have been synthesised from the corresponding arene ruthenium dichloride dimers and enantiopure (R1R or S1S) trans-1,2-diaminocyclohexane (H2N?NH2) and isolated as the chloride salts. The compounds are all water-soluble and, in the case of the hexamethylbenzene derivative 3, the aqua complex formed upon hydrolysis [(C6Me 6)Ru(H2N?NH2)-OH2]2+ (4) could be isolated as the tetrafluoroborate salt. The molecular structures of 3 and 4 have been determined by single-crystal X-ray diffraction analyses of [(C6Me6)Ru(H2N?NH2)Cl]Cl and [(C6Me6)Ru(H2N?NH2)OH 2][BF4]2. Treatment of [Ru2(arene) 2Cl4] with the monotosylated trans-1,2-diaminocyclohexane derivative (TsHN?NH2) does not yield the expected cationic complexes, analogous to 1-3 but the neutral deprotonated complexes [(arene)Ru(TsN?NH2)Cl] (5: arene = C6H6; 6: arene = p-MeC6H4iPr; 7: arene = C6Me 6; 8: arene = C6H5COOMe). Hydrolysis of the chloro complex 7 in aqueous solution gave, upon precipitation of silver chloride, the corresponding monocationic aqua complex [(C6Me 6)Ru(TsHN?NH2)(OH2)]+ (9) which was isolated and characterised as its tetrafluoroborate salt. The enantio-pure complexes 1-9 have been employed as catalysts for the transfer hydrogenation of acetophenone in aqueous solution using sodium formate and water as a hydrogen source. The best results were obtained (60C) with 7, giving a catalytic turnover frequency of 43 h-1 and an enantiomeric excess of 93 %. Wiley-VCH Verlag GmbH & Co. KGaA, 2005.

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, Formula: C12H12Cl4Ru2.

The dinuclear dichloro complexes [(eta6-arene)2Ru2(mu-Cl)2Cl2] and [(eta5-C5Me5)2M2(mu-Cl)2Cl2] react with 2-(pyridine-2-yl)thiazole (pyTz) to afford the cationic complexes [(eta6-arene)Ru(pyTz)Cl]+ (arene = C6H6 1, p-iPrC6H4Me 2 or C6Me6 3) and [(eta5-C5Me5)M(pyTz)Cl]+ (M = Rh 4 or Ir 5), isolated as the chloride salts. The reaction of 2 and 3 with SnCl2 leads to the dinuclear heterometallic trichlorostannyl derivatives [(eta6-p-iPrC6H4Me)Ru(pyTz)(SnCl3)]+ (6) and [(eta6-C6Me6)Ru(pyTz)(SnCl3)]+ (7), respectively, also isolated as the chloride salts. The molecular structures of 4, 5 and 7 have been established by single-crystal X-ray structure analyses of the corresponding hexafluorophosphate salts. The in vitro anticancer activities of the metal complexes on human ovarian cancer cell lines A2780 and A2780cisR (cisplatin-resistant), as well as their interactions with plasmid DNA and the model protein ubiquitin, have been investigated.

37366-09-9, Name is Dichloro(benzene)ruthenium(II) dimer, molecular formula is C12H12Cl4Ru2, belongs to ruthenium-catalysts compound, is a common compound. In a patnet, once mentioned the new application about 37366-09-9, Recommanded Product: 37366-09-9

The “one-pot” generation of a tris-cationic homobimetallic racemic planar-chiral ruthenacyclic ruthenium sandwich complex from a reaction of the metal-free chelating ligand with the (-6-benzene) dichloridoruthenium(II) dimer in acetonitrile is reported. This unexpected complex, which was characterized by structural X-ray diffraction analysis, is the product of a multistep process entailing first the cycloruthenation of the ligand, a ligand exchange reaction, and eventually the site-selective pi-bonding of a bis-cationic [(-6-benzene)Ru]2+ moiety to a monocationic ruthenacyclic intermediate. Investigations of the underlying electronic structure and bonding scheme by resorting to quantum chemical methods of the density functional theory have revealed the key role played by the electron-donating NMe2 substituent, which enables the a priori antagonistic pi-coordination of the in situ-formed cationic ruthenacycle by a dicationic (-6-arene) ruthenium(II) moiety. Experimental evidence indicates indeed that, in the absence of such an electron-donating group at the metalacycle, the pi-coordination of the [(-6-benzene)Ru] 2+ cannot take place.

A ruthenium complex, KNa[Ru2(C6H6) 2(CH3COO)6] (Ru-KNa), and its polyoxotungstate derivative, Na6[{Ru(C6H6)}2W 8O28(OH)2]·16H2O (Ru-Na), have been successfully isolated from routine synthetic reactions and characterized by X-ray single-crystal structure analysis, IR spectroscopy and elemental analysis. A remarkable aspect of Ru-KNa is that it has two ligand types, benzene and acetate, and the acetate ligands are connected exclusively by a central Na cation to form a dimeric sandwich-type structure, which is further connected by K cations to construct the 3D structures. Based on complex Ru-KNa, the compound Ru-Na was synthesized, and it consists of two {Ru(C 6H6)} units linked to a [W8O 28(OH)2]10- fragment by three Ru-O(W) bonds to result in an assembly with idealized C2 symmetry in which the polyanions form 3D structures by the connection of Na chains. Subsequently, the compound Ru-Na was anchored on (3-aminopropyl)triethoxysilane (apts) modified SBA-15 to prepare the solid catalysts, which were characterized by powder XRD, N2 adsorption measurements and FTIR spectroscopy. Finally, the catalytic efficiency of Ru-Na was assessed in the oxidation of n-hexadecane with air without any additives and solvents. The results indicated that Ru-Na is a heterogeneous catalyst and exhibits higher catalytic activity than previously reported Ru-containing polyoxotungstates. Copyright

1H-Benzoimidazole on subjection to a sequence of reactions with benzyl bromide, PhECH2Cl (E = S, Se), and elemental S or Se results in 1-benzyl-3-phenylchalcogenylmethyl-1,3-dihydrobenzoimidazole-2-chalcogenones (L1-L4), which are unsymmetrical bidentate chalcogen ligands having a unique combination of chalcogenoether and chalcogenone donor sites. Half sandwich complexes, [(eta6-C6H6)Ru(L)Cl][PF 6] (1-4), have been synthesized by reactions of [(eta6- C6H6)RuCl(mu-Cl)]2 with the appropriate L at room temperature followed by treatment with NH4PF6. L1-L4 and their complexes 1-4 have been authenticated with HR-MS and 1H, 13C{1H}, and 77Se{1H} NMR spectra. The single-crystal structures of 1-4 have been determined by X-ray crystallography. Each L acts as an unsymmetric (E,E) or (E,E’) bidentate ligand. The Ru atom in 1-4 has pseudo-octahedral half-sandwich “piano-stool” geometry. The Ru-S and Ru-Se bond distances (A) respectively are 2.358(3)/2.3563(18) and 2.4606(11)/2.4737(10) (thio- and selenoether), and 2.4534(17)/2.435(3) and 2.5434(9)/2.5431(10) (thione and selone). Catalytic activation with complexes 1-4 has been explored for the transfer hydrogenation (TH) of aldehydes and ketones using various sources of hydrogen. 2-Propanol and glycerol have been compared and found most suitable among the sources screened. The catalytic efficiency of other sources explored, viz. formic, citric, and ascorbic acid, is dependent on the pH of reaction medium and is not promising. A comparative study of 2-propanol and glycerol as hydrogen sources for catalytic activation of TH with 1-4 has revealed that with glycerol (for comparable conversion in the same time) more amount of catalyst is needed in comparison to that of 2-propanol. The catalytic process is more efficient with 3 (where Ru is bonded with selone), followed by 1 ? 4, and 2 showing the least activity among all four complexes. The transfer hydrogenation involves an intermediate containing a Ru-H bond and follows a conventional alkoxide intermediate based mechanism. The results of DFT calculations appear to be generally consistent with experimental catalytic efficiencies and bond lengths/angles.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.category: ruthenium-catalysts, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 37366-09-9, in my other articles.

Novel [Ru(L)(Tpms)]Cl and [Ru(L)(TpmsPh)]Cl complexes (L = p-cymene, benzene, or hexamethylbenzene, Tpms = tris(pyrazolyl)methanesulfonate, TpmsPh = tris(3-phenylpyrazolyl)methanesulfonate) have been prepared by reaction of [Ru(L)(mu-Cl)2]2 with Li[Tpms] and Li[TpmsPh], respectively. [Ru(p-cymene)(Tpms)]BF4 has been synthesized through a metathetic reaction of [Ru(p-cymene)(Tpms)]Cl with AgBF4. [RuCl(cod)(Tpms)] (cod = 1,5-cyclooctadiene) and [RuCl(cod)(TpmsPh)] are also reported, being obtained by reaction of [RuCl2(cod)(MeCN)2] with Li[Tpms] and Li[Tpms Ph], respectively. The structures of the complexes and the coordination modes of the ligands have been established by IR, NMR, and single-crystal X-ray diffraction (for [RuL(Tpms)]X (L = p-cymene or HMB, X = Cl; L = p-cymene, X = BF4)) studies. Electrochemical studies showed that each complex undergoes a single-electron RuII ? Ru III oxidation at a potential measured by cyclic voltammetry, allowing to compare the electron-donor characters of the tris(pyrazolyl)methanesulfonate and arene ligands, and to estimate, for the first time, the values of the Lever EL ligand parameter for TmpsPh, HMB, and cod.

The molecular targets and the modes of action behind the cytotoxicity of two structurally established N,O- or N,N-hydrazone ruthenium(II)?arene complexes were explored in human breast adenocarcinoma cells (MCF-7) and paralleled in non-cancerous and cisplatin-resistant counterparts (MCF-10A and MCF-7CR respectively). Both complexes, [Ru(hmb)(L1)Cl] (1, L1=4-((2-(2,4-dinitrophenyl)hydrazono)(phenyl)methyl)-3-methyl-1-phenyl-1H-pyrazol-5-olate) and [Ru(cym)(L2)Cl] (2, L2=1-((3-methyl-5-oxo-1-phenyl-1H-pyrazol-4(5H)-ylidene)(phenyl)methyl)-2-(pyridin-2-yl)hydrazin-1-ide), reversibly interact with moderate-to-high affinity with a number of molecular targets in cell-free assays, namely serum albumin, DNA, the 20S proteasome and hydroxymethylglutaryl-CoA reductase. Most interestingly, only 2 readily crosses the cell membrane and preserves its binding/modulatory ability toward the targets of interest upon rapid cellular internalization. The resulting action at multiple levels of the cancer cascade is likely the cause for the selective sensitization of tumour cells to p27-mediated apoptotic death, and for the ability of 2 to overcome the drug resistance problem.

Formate salts are important chemicals widely used in everyday products. The current industrial-scale manufacture of formates requires CO at high pressure and harsh reaction conditions. Herein, we describe a new process for these products without the utilization of hazardous gases and chemicals. By application of ruthenium pincer complexes, a simultaneous methanol dehydrogenation and bicarbonate hydrogenation reaction proceeds, which provides a green synthesis of formate salts with excellent TON (>18 000), TOF (>1300 h-1), and yield (>90 %). Get rid of CO and H 2: An efficient route for the industrial synthesis of formate salts without the utilization of carbon monoxide is highly desirable. A catalytic reaction combining methanol dehydrogenation and bicarbonate hydrogenation has been developed, which provides a green and cost-efficient process for the synthesis of formate salts with excellent turnover numbers and yields.

New benzoyl- and naphthoyl-substituted phosphines have been synthesized, which are stable to air and moisture. Testing these so-called phosphomide ligands in the presence of different ruthenium precursors, the hydrogenation of sodium bicarbonate (NaHCO3) to sodium formate (NaHCO2) proceeded with good catalyst turnover numbers in the range of 1300-1600 at 80 C and a total pressure of hydrogen of 60 bar in the absence of amines or other additives. Similarly, catalytic hydrogenations of carbon dioxide, cinnam-, and benzaldehyde were possible with these new ruthenium complexes. As an intermediate of the catalytic cycle the defined ruthenium complex [(eta6-C6H6)-RuCl2(Cy 2P(1-naphthoyl)] (Cy=cyclohexyl) was prepared and characterized by X-ray crystallography. Ruthenium and phosphor work wonders: Air-stable ruthenium phosphomide complexes are active catalysts in the hydrogenation of sodium bicarbonate, carbon dioxide, and carbonyl compounds. Hydrogenation proceeds with high catalyst turnover numbers in the absence of amines or other additives. The application range of these new ruthenium catalysts also includes the hydrogenation of cinnamaldehyde and benzaldehyde. Copyright
