The new carbazole N,N? ligand containing [(eta5-C5Me5)MCl(L)]PF6, (M = Ir (1) and Rh (2)) and [(eta6-C6H6)RuCl(L)]PF6 (3) (C5Me5 = pentamethylcyclopentadienyl, L = 9-ethyl-N-(pyridine-2-yl methylene)-9H-carbazole-3-amine) complexes has been synthesized and characterized by 1H NMR, 13C NMR, 2D NMR, melting point analysis, electronic absorption, infrared spectroscopy, HR-Mass spectroscopy and elemental analyses. The crystal structure of the [(eta5-C5Me5)RhCl(L)]PF6 has been confirmed by single crystal XRD. The anticancer study of the synthesized complexes 1?3 clearly showed a potent inhibitor of human breast cancer cells (MCF-7) under in vitro conditions. The inhibitory concentrations (IC50) of the complexes 1?3 were determined at low (5, 6 and 8 muM) concentration against the MCF-7 human breast cancer cell line. Further cytotoxic, cell cycle and nuclear studies confirmed that the novel half sandwich Ir(III), Rh(III) and Ru(II) complexes could be effective against MCF-7 human breast cancer cell proliferation. Moreover the results indicate that anticancer in vitro activity of complexes 1?3 falls in the order of 1 > 2 > 3. A molecular docking study of the complexes 1?3 showed the nature of binding energy, H-bond and hydrophobic interactions with the cyclooxygenase-2 (COX-2) receptor.

The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.15746-57-3, Name is Cis-Dichlorobis(2,2′-bipyridine)ruthenium(II), molecular formula is C20H16Cl2N4Ru.

The tetranuclear ruthenium complex {Ru[(tpphz)Ru(bpy)2]3}8+, where tpphz is tetrapyrido[3,2-a:2? ,3? -c:3? 2? -h:2? ,3? -j]phenazine, has been synthesized by reaction of [Ru(tpphz)3]2+ with [Ru(bpy)2Cl2] and by reaction of [Ru(bpy)2(tpphz)]2+ with [Ru(DMSO)4Cl2]. The large distance between the chiral centers allows full 1H NMR interpretation despite the mixture of eight stereoisomers. The tetranuclear complex was further characterized by electrospray mass spectrometry and by the wide-angle X-ray scattering technique, which confirmed the starburst geometry. The photophysical properties of the tetranuclear complex in acetonitrile were studied and compared with those of [Ru(tpphz)3]2+ (1 × 10-4 M acidic solution) and [(bpy)2Ru(tpphz)Ru(bpy)2]4+ model molecules. The tetranuclear complex gives rise to a single emission, attributed to metal-to-ligand charge-transfer states involving peripheral Ru centers and tpphz bridging ligands.

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.Safety of Cis-Dichlorobis(2,2′-bipyridine)ruthenium(II), you can also check out more blogs about15746-57-3

The synthesis of the first example of a bime-tallic complex spanned by the C4H alkynylvinylidene ligand, [Cl(CO)2L 2RuC?CCH=C-RuL2(eta-C5H 5]PF6 (L = PPh3), is reported: the reaction of [Ru(CO)2L3] with butadiyne provides [RuH(C?CC? CH)(CO)2L2], which is converted to the chloro derivative [RuCl(C?CC?CH)-(CO)2L2] by N-chlorosuccinimide. Subsequent treatment with [Ru(thf)L2(eta- C5H5)]PF6 provides [Cl(CO)2L 2RuC? CCH=C=RuL2(eta-C5H 5)]PF6, deprotonation of which affords [Cl(CO) 2L2RuC?CC?CRuL2(eta-C 5H5)].

The trimetallic complexes {Ru(PPh3)2Cp}2{mu-M(CN)4} and {Ru(dppe)Cp*}2{mu-M(CN)4} (M = Ni, Pd, Pt) have been prepared from reactions of RuCl(PPh3)2Cp or RuCl(dppe)Cp* with the appropriate tetracyanometallate salt, and structurally characterised. While a similar reaction of FeCl(dppe)Cp with K2[Pt(CN)4] afforded {Fe(dppe)Cp}2{mu-Pt(CN)4}, the iron cyanide complex Fe(CN)(dppe)Cp was isolated as the only iron containing product from reaction of FeCl(dppe)Cp with K2[Ni(CN)4]. The trimetallic complexes can be oxidised in two sequential one-electron steps. Spectroelectrochemical experiments reveal weak NIR absorption bands in the mono-oxidised complexes which are not present in the binuclear complex K[Ru(dppe)Cp*{Pt(CN)4}], and are therefore attributed to RuII ? RuIII charge transfer processes. The coupling parameter, Vab, extracted using Hush-style analysis falls in the range 250 ± 50 cm-1, consistent with the weak interaction between the Group 8 metal centres. The energy of the IVCT process is dominated by reorganisation energy of the Group 8 metal-ligand fragment.

The synthesis of [{RuCl2(eta6-o-MeC6H4CO 2Me)}2], (o-MeC6H4CO2Me = methyl o-toluate), from RuCl3·3H2O and methyl 1,4-dihydro-o-toluate is reported. This is the first example of an arene-ruthenium complex having planar chirality with respect to the face of the co-ordinated arene. Its reactions with tertiary phosphines and primary amines have been examined. Using optically active amines, the complexes [RuCl2(eta6-o-MeC6H4CO 2Me) L?] [L? = (-)(S)-1-phenylethylamine or (+)-dehydroabietylamine], and [RuCl(eta6-o-MeC6H4CO 2Me)(N-N)]PF6 [N-N = (-)(R,R)-1,2-diphenyl-1,2-diaminoethane], have been obtained as diastereomeric mixtures. The diastereomers of [RuCl2(eta6-o-MeC6H4CO 2Me){(-)(S)-MeCH(Ph)NH2}] have been partially separated by fractional crystallisation, the less soluble one being obtained with > 90% enrichment. Their circular dichroism spectra have been compared with those of complexes containing achiral arene-ruthenium moieties.

A document type is Article, introducing its new discovery.

The (COOH)2 oxidation reaction was studied at potentials below which the oxygen evolution reaction (OER) takes place. Pt was found to catalyze the (COOH)2 oxidation reaction more strongly than Au, while Ru did not display any activity toward the (COOH)2 oxidation reaction. Furthermore, under rapid stirring conditions, the (COOH)2 oxidation reaction using Pt electrodes was shown to be activation controlled. Therefore, the (COOH)2 oxidation currents can be related to the electroactive Pt area, as shown for a range of polycrystalline, bulk metal Pt, and Pt powder electrodes. The Pt surface area for multicomponent catalyst systems can also be estimated by combining (COOH)2 oxidation data with the charge needed to oxidize adsorbed CO to CO2 (COads charge), as shown for a range of Pt- and Ru-containing powder electrodes. In fact, the combination of the two methods [(COOH)2 oxidation current and COads charge] can be used as an in situ probe to estimate the fraction of Ru in the metallic state in the potential region where CO is adsorbed provided the surface ratio of Pt vs. Ru is known.

Cyclic phosphopeptides were prepared using ring-closing metathesis followed by phosphopeptides. These cyclic phosphopeptides were designed to interact with the SH2 domain of Grb2, which is a signal transduction protein of importance as a target for antiproliferative drug development. Binding of these peptides to the Grb2 SH2 domain was evaluated by a surface plasmon resonance assay. High affinity binding to the Grb2 SH2 domain was maintained upon macrocyclization, thus indicating that this method can be used to assemble high affinity cyclic phosphopeptides that interfere with signal transduction cascades.
