The rate of hydrogenation of gamma-ketoesters MeCOCH2CH 2COOR (R = Et, Pri, But) in the presence of the chiral RuII-BINAP catalyst (BINAP is 2,2?- bis(diphenylphosphino)-1,1?-binaphthyl) greatly increases upon the addition of 5-10 equivalents of HCl with respect to ruthenium. In the hydrogenation of ethyl levulinate, the optically active gamma-hydroxy ester initially formed would cyclize by ?95% to give gamma-valerolactone with optical purity of 98-99% ee. When the Ru(COD)(MA)2-BINAP-HCl catalytic system is used (COD is 1,5-cyclooctadiene, MA is 2-methylallyl), complete conversion of the ketoester (R = Et) in EtOH is attained in 5 h at 60C under an H2 pressure of 60-70 atm.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Formula: C12H12Cl4Ru2, you can also check out more blogs about37366-09-9

Arene ruthenium complexes [(eta6-arene)Ru(sacc) 2(OH2)] (arene = para-cymeme, benzene) containing an aqua and two saccharinato ligands have been synthesized from [(eta6- arene)RuCl2]2 and sodium saccharinate in a water-ethanol mixture (1:1). The aqua complex [(eta6-MeC6H 4Pri)Ru(sacc)2(OH2)] reacts with acetonitrile to give the acetonitrile complex [(eta6-MeC 6H4Pri)Ru(sacc)2(NCMe)]. The corresponding benzene derivative [(eta6-C6H 6)Ru(sacc)2(NCMe)] was obtained from [(eta6- C6H6)RuCl2]2 and saccNa in an acetonitrile-methanol mixture (1:1). All new complexes show a piano-stool geometry with two mono-hapto nitrogen-bonded saccharinato ligands in addition to a H2O or MeCN ligand. All complexes of the type [(eta6- arene)Ru(sacc)2(OH2)] and [(eta6-arene) Ru(sacc)2(NCMe)] were found to catalyze the oxidation of secondary alcohols with tert-butyl hydroperoxide (ButOOH) to give the corresponding ketones in aqueous solution.

Five new complexes of the type [RuCl2(NHC)(eta6-arene)] (4, 5, and 6) and [RuCl(NHC)(eta6-arene)(PR3)]Cl (7 and 8) (NHC[dbnd]N-heterocyclic carbene = bmim, emim; arene = benzene, p-cymene; PR3 = PPh3 or pta = 1,3,5-triaza-7-phosphaadamantane) were synthetized and applied as catalysts (together with the known [RuCl2(bmim)(eta6-p-cymene)] (3) with and without added PPh3) in racemization of optically active secondary alcohols in toluene. The highest catalytic activity, TOF = 9.3 h?1 (ee as low as 1.3% in 4 h at 95 C) was observed in racemization of (S)-1-phenylethanol with a catalyst (4 mol%) prepared in situ from 3 and 1 equivalent of PPh3. It is of practical significance that formation of acetophenone byproduct was suppressed to 3.5% by 17% v/v isopropanol in toluene. DFT calculations revealed that the rate determining step in the suggested reaction mechanism was the agostic coordination of hydrogen on the chiral carbon atom of the alcohol substrate.

The reaction of half-sandwich complexes of ruthenium, rhodium, and iridium with amino-substituted 3-hydroxy-2-pyridone ligands in aqueous solution gives monomeric O,O?-chelate complexes. Upon addition of base, the complexes assemble to form trimeric metallamacrocycles, as evidenced by NMR spectroscopy and single-crystal X-ray analyses. The macrocycles are able to act as highly selective receptors for lithium ions. The binding constants depend on the nature of the half-sandwich complex, the ligand, and the pH. With a commercially available (cymene)Ru complex, a receptor with a Li+ binding constant of Ka = 5.8 (±1.0) × 104 M-1 and a Li+-Na+ selectivity of 10 000:1 can be obtained. The fact that the assembly process of the receptor is pH-dependent can be used to detect the presence of lithium ions by a pH measurement. Furthermore, it is possible to transduce the binding of Li+ into a change of color by means of a chemical reaction with FeCl3. This allows the detection of Li + in the pharmacologically relevant concentration range of 0.5-1.5 mM by the “naked eye”.

A series of p-cymene ruthenium dichloro complexes containing isonicotinic ester ligands, [(arene)RuCl2NC5H4-4-COO-C 6H4-p-O-(CH2)n-CH3] (n = 1: 1, n = 3: 2, n = 5: 3, n = 7: 4, n = 9: 5, n = 11: 6, n = 13: 7, n = 15: 8), were prepared from p-cymene ruthenium dichloro dimer and the corresponding isonicotinic ester ligand. The single-crystal X-ray analysis of 1 shows the molecule to adopt the usual pseudo-tetrahedral piano-stool geometry, the isonicotinic ester ligand being coordinated through the nitrogen atom. The cytotoxicity of all complexes and of the free ligands was studied towards human ovarian cancer cells; high activities were observed only for n = 9 (presenting a chain with ten carbon atoms), both as far as the free ligands and the complexes are concerned. Based on this result, a new isonicotinic ester ligand with a C10 substituent containing a terminal alcohol function, NC 5H4-4-COO-C6H4-p-O-(CH 2)10-OH, was synthesized by a four-step method, and arene ruthenium complexes thereof, [(arene)RuCl2NC5H 4-4-COO-C6H4-p-O-(CH2) 10-OH] (arene = C6H6: 9a, arene = p-MeC 6H4Pri: 9b, arene = C6Me 6: 9c) were prepared. The complexes 9a and 9b show indeed remarkable anticancer activities, the IC50 values for human ovarian cancer cells being in the submicromolar range. The highest cytotoxicity was observed for complex 9b, with IC50 values of 0.18 muM for A2780 and 3.04 muM for the cisplatin-resistant mutant A2780cisR.

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.

A new series of amphiphilic eta6-areneruthenium(II) compounds containing phenylazo ligands (group I: compounds 1a, 1b, 2a and 2b) and phenyloxadiazole ligands (group II: compounds 3a, 3b, 4a and 4b) were synthesized and characterized for their anti-glioblastoma activity. The effects of the amphiphilic eta6-areneruthenium(II) complexes on the viability of three human glioblastoma cell lines, U251, U87MG and T98G, were evaluated. The azo-derivative ruthenium complexes (group I) showed high cytotoxicity to all cell lines, whilst most oxadiazole-derivative complexes (group II) were less cytotoxic, except for compound 4a. The cationic complexes 2a, 2b and 4b were more cytotoxic than the neutral complexes. Compounds 2a and 2b caused a significant reduction in the percentage of cells in the G0/G1 phase, with concomitant increases in the G2/M phase and fragmented DNA in the T98G cell line. The eta6-areneruthenium(II) compounds were also tested in cell lines that overexpress the multidrug ABC transporters P-gp, MRP1 and ABCG2. Compounds 2b and 4a were substrates for the P-gp protein, with resistance indexes of 8.6 and 1.9, respectively. Compound 2b was also a substrate for ABCG2 and MRP1 proteins, with lower resistance indexes (1.8 and 1.6, respectively). The contribution of multidrug ABC transporters to the cytotoxicity of compound 2b in T98G cells was evidenced, since verapamil (a characteristic inhibitor of MRP1) increased the cytotoxicity of compound 2b at concentrations up to 20 mumol L?1, whilst GF120918 and Ko143 (specific inhibitors of P-gp and ABCG2, respectively) had no significant effect. In addition, we showed that compound 2b interacts with glutathione (GSH), which could explain its cellular efflux by MRP1. Our results showed that the amphiphilic eta6-areneruthenium(II) complexes are promising anti-glioblastoma compounds, especially compound 2b, which was cytotoxic for all three cell lines, although it is transported by the three main multidrug ABC transporters.

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.

Halfsandwich complexes of ruthenium, rhodium and iridium with deprotonated N,N?,N?-tripeptide ester ligands were obtained from chloro bridged compounds and tripeptide methyl esters (1-6) or by peptide synthesis at a metal centre (9-15). For the peptide synthesis at the complex (C6Me6)Ru coordinated dipeptide methyl esters from glycine and beta-alanine or gamma-amino butyric acid were elongated by an alpha-amino acid methylester. The tripeptide ester Ru(eta6-C6Me6) complexes with chiral amino acid components and an “asymmetric” metal atom are formed with high diastereoselectivity. The tripeptide esters Gly-Gly-beta-AlaOMe, Val-Gly-beta-AlaOMe and Phe-Gly-beta-AlaOMe can be condensated at the (C6Me6)Ru complex with sodium methanolate to give triple deprotonated cyclic tripeptides.
