A document type is Article, introducing its new discovery.

The synthesis and structures of a series of new water-soluble phosphine ligands based on 1,3,5-triaza-7-phosphaadamantane (PTA) are described. Insertion of aldehydes or ketones into the C-Li bond of 1,3,5-triaza-7-phosphaadamantan- 6-yllithium (PTA-Li) resulted in the formation of a series of slightly water-soluble beta-phosphino alcohols (PTA-CRR?OH, R = C 6H5, C6H4OCH3, ferrocenyl; R? = H, C6H5, C6H 4OCH3) derived from the heterocyclic phosphine PTA. Insertion of CO2 yielded the highly water-soluble carboxylate PTA-CO2Li, S25 ? 800 g/L. The compounds have been fully characterized in the solid state by X-ray crystallography and in solution by multinuclear NMR spectroscopy. The addition of PTA-Li to symmetric ketones results in a racemic mixture of PTA-CR2OH ligands with a single resonance in the 31P{1H} NMR spectrum between -95 and -97 ppm. The addition of PTA-Li to aldehydes results in a mixture of diasteromeric compounds, PTA-CHROH, with two 31P{1H} NMR resonances between -100 and -106 ppm. Three (eta6-arene)RuCl 2(PTA-CRR?OH) complexes of these ligands were synthesized and characterized, with the ligands binding in a kappa1 coordination mode. All the ligands and ruthenium complexes are slightly soluble in water with S25 = 3.9-11.1 g/L for the PTA-CRR?OH ligands and S 25 = 3.3-14.1 g/L for the (eta6-arene)RuCl 2(PTA-CRR?OH) complexes.

The reactions of [RuCl(mu-Cl)(eta6-p-cymene)]2 with sodium carboxylates, in methanol or acetonitrile solution, afforded the complexes [RuCl(kappa2O-RCO2)(eta6-p-cymene)] (RCO2 = valproate, 1; aspirinate, 2; diclofenate, 3), in 79?96% yields. Analogously, [RuCl(kappa2O-dfCO2)(eta6-benzene)], 4, was obtained in admixture with minor by-products from [RuCl(mu-Cl)(eta6-benzene)]2 and sodium/silver diclofenate. The sequential reaction of [RuCl(mu-Cl)(eta6-p-cymene)]2 with sodium salicylate and PPh3 gave [Ru(kappa2O,O?-salCO2)(PPh3)(eta6-p-cymene)], 5, in 70% yield. The hydride complex [Ru2Cl2(mu-Cl)(mu-H)(eta6-p-cymene)2], 6, was produced in 36% yield from [RuCl(mu-Cl)(eta6-p-cymene)]2 and sodium formate. An optimization of the experimental work-up allowed to isolate [RuCl(mu-Cl)(eta6-p-cymene)]2 with an improved yield respect to the literature (98% vs. 65%). The bidentate coordination mode of the carboxylato ligands in 1?5 was unambiguously ascertained by IR and NMR spectroscopy, moreover the solid state structure of 1 was elucidated by single crystal X-ray diffraction. Complexes 1?3 experience rapid and quantitative dissociation of the carboxylato anion in DMSO/water/NaCl mixtures, mainly converting into [RuCl2(DMSO)(eta6-p-cymene)], 7.

Application of 37366-09-9, An article , which mentions 37366-09-9, molecular formula is C12H12Cl4Ru2. The compound – Dichloro(benzene)ruthenium(II) dimer played an important role in people’s production and life.

We report a practical one-pot synthesis of dialkylammonium salts of anionic dinuclear ruthenium complexes having chelating diphosphine ligands, BINAPs and DPB, with formula of [NEt2H2][{RuCl(diphosphine)}2(mu-Cl) 3] [2a: diphosphine = 2,2?-bis-(diphenylphosphino)-1,1?-binaphthyl; 6a: 2,2?-bis(di(p-tolyl)phosphino)-1,1?-binaphthyl; 8a: 1,2-bis(diphenylphosphino)benzene]. Treatment of cationic ruthenium complexes, [RuCl(eta6-p-cymene)(diphosphine)]Cl (4) with a slight excess of NEt2H2Cl (5a) afforded 2a, 6a, and 8a in quantitative yields. Similar reactions with various dialkylammonium salts 5b-f gave the corresponding salts, [NR2H2][{RuCl(diphosphine)}2(mu-Cl) 3]. A one-pot mixture of BINAP or its derivative, [RuCl2(eta6-arene)]2, and NR2H2Cl produced salts of the anionic dinuclear complexes which can be applied as catalysts for the asymmetric hydrogenation of ketonic substrates such as acetol and methyl acetoacetate with high activity and high enantioselectivity. The anionic face-sharing bioctahedral structure of these complexes was confirmed by the X-ray analysis of 8a, which has two hydrogen bonds between two NH of the diethylammonium cation and two terminal chloro-ligands.

The synthesis and characterization of ruthenium(II) arene complexes [(eta6-arene)Ru(N,N)Cl]0/+, where N,N = 2,2?-bipyridine (bipy), 2,2?-bipyridine-3,3?-diol (bipy(OH)2) or deprotonated 2,2?-bipyridine-3,3?-diol (bipy(OH)O) as N,N-chelating ligand, arene = benzene (bz), indan (ind), biphenyl (bip), p-terphenyl (p-terp), tetrahydronaphthalene (thn), tetrahydroanthracene (tha) or dihydroanthracene (dha), are reported, including the X-ray crystal structures of [(eta6-tha)Ru(bipy)Cl][PF6] (1), [(eta6-tha)Ru(bipy(OH)O)Cl] (2) and [(eta6-ind) Ru(bipy(OH)2)Cl][PF6] (8). Complexes 1 and 2 exibit CH (arene)/pi (bipy or bipy(OH)O) interactions. In the X-ray structure of protonated complex 8, the pyridine rings are twisted (by 17.31). In aqueous solution (pH = 2-10), only deprotonated (bipy(OH)O) forms are present. Hydrolysis of the complexes was relatively fast in aqueous solution (t 1/2 = 4-15 min, 310 K). When the arene is biphenyl, initial aquation of the complexes is followed by partial arene loss. Complexes with arene = tha, thn, dha, ind and p-terp, and deprotonated bipyridinediol (bipy(OH)O) as chelating ligands, exhibited significant cytotoxicity toward A2780 human ovarian and A549 human lung cancer cells. Complexes [(eta6-bip)Ru(bipy(OH) O)Cl] (7) and [(eta6-bz)Ru(bipy(OH)O)Cl] (5) exhibited moderate cytotoxicity toward A2780 cells, but were inactive toward A549 cells. These activity data can be contrasted with those of the parent bipyridine complex [(eta6-tha)Ru(bipy)Cl][PF6] (1) which is inactive toward both A2780 ovarian and A549 lung cell lines. DFT calculations suggested that hydroxylation and methylation of the bipy ligand have little effect on the charge on Ru. The active complex [(eta6-tha)Ru(bipy(OH)O)Cl] (2) binds strongly to 9-ethyl-guanine (9-EtG). The X-ray crystal structure of the adduct [(eta6-tha)Ru(bipy(OH)O)(9-EtG-N7)][PF6] shows intramolecular CH (arene)/pi (bipy(OH)O) interactions and DFT calculations suggested that these are more stable than arene/9-EtG pi-pi interactions. However [(eta6-ind)Ru(bipy(OH)2)Cl][PF6] (8) and [(eta6-ind)Ru(bipy)Cl][PF6] (16) bind only weakly to DNA. DNA may therefore not be the major target for complexes studied here.

Related Products 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.

Hydrogenation is a core technology in chemical synthesis. High rates and selectivities are attainable only by the coordination of structurally well-designed catalysts and suitable reaction conditions. The newly devised [RuCl2-(phosphane)2(1,2-diamine) ] complexes are excellent precatalysts for homogeneous hydrogenation of simple ketones which lack any functionality capable of interacting with the metal center. This catalyst system allows for the preferential reduction of a C=O function over a coexisting C=C linkage in a 2-propanol solution containing an alkaline base. The hydrogenation tolerates many substituents including F, Cl, Br, I, CF3, OCH3, OCH2C6H5, COOCH(CH3)2, NO2, NH2, and NRCOR as well as various electron-rich and -deficient heterocycles. Furthermore, stereoselectivity is easily controlled by the electronic and steric properties (bulkiness and chirality) of the ligands as well as the reaction conditions. Diastereoselectivities observed in the catalytic hydrogenation of cyclic and acyclic ketones with the standard triphenylphosphane/ethylenediamine combination compare well with the best conventional hydride reductions. The use of appropriate chiral diphosphanes, particularly BINAP compounds, and chiral diamines results in rapid and productive asymmetric hydrogenation of a range of aromatic and heteroaromatic ketones and gives a consistently high enantioselectivity. Certain amino and alkoxy ketones can be used as substrates. Cyclic and acyclic alpha,beta-unsaturated ketones can be converted into chiral allyl alcohols of high enantiomeric purity. Hydrogenation of configurationally labile ketones allows for the dynamic kinetic discrimination of diastereomers, epimers, and enantiomers. This new method shows promise in the practical synthesis of a wide variety of chiral alcohols from achiral and chiral ketone substrates. Its versatility is manifested by the asymmetric synthesis of some biologically significant chiral compounds. The high rate and carbonyl selectivity are based on nonclassical metal-ligand bifunctional catalysis involving an 18-electron amino ruthenium hydride complex and a 16-electron amido ruthenium species.

Metal complexes-catalyzed hydrolysis and alcoholysis of organic substrates such as alkenyl esters, alkenyl ethers, and azlactones (oxazol-5(4H)-ones) are described. These reactions were applied for kinetic resolution of chiral compounds and high selectivities were achieved with vinyl ethers of 2-substituted cyclohexanols, 1,1?-bi-2-naphthols, 1,1?-bi-2-phenols, and 4,4-disubstituted azlactones. Oxidative carbon-carbon bond cleavage reactions, which were found in the course of the study of asymmetric hydrolysis were also described.

By 11B NMR spectroscopy all these compounds have pseudocloso geometries, in which the C(1) … C(2) connectivity is broken and an approximately square M(3)C(1)B(6)C(2) face is generated. Crystallographic studies on 2 and 3 confirm this suggestion. It is suggested that distortion in these species arises from steric crowding between the Cphenyl substituents, forced to adopt conformations with high theta values by the presence of the eta-bonded substituent at M(3). Individual gauge for localised orbitals calculations, reported for the first time on transition-metal heteroboranes, reasonably reproduce the (previously assigned) 11B NMR chemical shifts of 3-(eta-C5Me5)-3,1,2-closo-RhC2B 9H11, and allow a tentative assignment of those of 1,2-Ph2-3-(eta-C5Me 5)-3,1,2-pseudocloso-RhC2B9H9.

The synthesis of new chiral N-monotosylated-1,2-diamines based on the (-)-menthol skeleton is presented. The elimination of HCl from neomenthyl chloride obtained from an Appel reaction led to p-menth-3-ene in excellent yield. Further functionalization of the double bond in p-menth-3-ene with chloramine-T gave the corresponding N-tosylaziridines, which upon reaction with sodium azide and subsequent reduction of the azide functional group, formed the 1,2-diamine system. The synthesized chiral ligands proved effective in the asymmetric transfer hydrogenation of aromatic ketones and an endocyclic imine.
