In (5)(PF6)2-(7)(PF6) 2, the nucleobase 9MeG binds to ruthenium through N7. Based on 1H NMR spectroscopy, a strong shielding effect between the aromatic ring system of the quinoxaline or benzo[g]quinoxaline moiety of the ligands pqx and pbqx and the H8 of 9MeG was observed. The complexes (1)-(4) are highly cytotoxic as chloride salts, against various cancer cell lines, with their IC50 values observed at less than 1 muMu.

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. 10049-08-8, Name is Ruthenium(III) chloride, molecular formula is Cl3Ru. In a Conference Paper，once mentioned of 10049-08-8, SDS of cas: 10049-08-8

The electrochemical oxidation of CH3OH at nanometer-scale PtRu catalyst materials is reported. Comparisons are made between the properties of a Johnson Matthey (JM) PtRu black sample (50 at.% Ru (XRu ? 0.5)) and PtRu particles (2-6 nm, nominally XRu ? 0.5) prepared by sonication under anhydrous conditions. Cyclic voltammetry and in situ infrared spectroscopy measurements show the catalysts are active for the oxidation, of 0.5 M CH3OH in 0.1 M HClO4 at temperatures between ambient and 70C. The sonochemically prepared PtRu sample displayed properties characteristic of bulk PtRu alloys with XRu ? 0.5. Evidence for phase separation of Pt and Ru was observed in CO stripping voltammetry from the JM catalyst adsorbed at low metal loadings (20 mug/cm2) on bulk Au electrodes. Per gram of catalyst, the JM material was more active toward CO 2 formation and displayed greater resistance to poisoning by adsorbed CO than the sonochemically prepared material during ambient temperature oxidation of 0.5 M CH3OH in 0.1 M HClO4.

Several dihydrogen complexes of ruthenium of the form [Cp/Cp*Ru(P-P)H2]+ (P-P = chelating diphosphine ligand) have been prepared by reaction of the corresponding neutral chloride complexes with H2 in the presence of NaB(ArF)4. Treatment with D2 or T2 gas leads to incorporation of deuterium or tritium in the dihydrogen ligand. Measurement of the resulting H-D and H-T couplings as a function of the temperature and magnetic field gives results consistent with computational studies which predict that the H-H bond distance will increase with temperature and will be significantly shortened by isotopic substitution. The degree of the observed temperature dependence is found to be a critical function of the ancillary ligand set.

Complexes of ruthenium containing 2-furan- and 2-thiophene-thiolates with phosphine ligands have been prepared and characterized. The bis(triphenylphosphine) complexes CpRu(PPh3)2SR (R = C4H3O: Fu (1a), C4H3S: Thi (1b)) were prepared by the reaction of thiolato anions (FuS- or ThiS-) with CpRu(PPh3)2Cl. The one-pot reaction of CpRu(PPh3)2Cl, thiolato anions and L ligands gave CpRu(L)SR (L = bis(diphenylphosphino)methane: dppm (2); bis(diphenylphosphino)ethane: dppe (3)). The newly prepared complexes have been characterized by spectroscopic techniques (FT-IR, 1H NMR and 31P NMR) and by elemental analysis. The crystal structure of CpRu(dppe)SThi (3b) has been determined by X-ray diffraction.

The dimeric palladium(I) complex [Pd(mu-Br)tBu 3P]2 was found to possess unique activity for the catalytic double-bond migration within unsaturated compounds. This isomerization catalyst is fully compatible with state-of-the-art olefin metathesis catalysts. In the presence of bifunctional catalyst systems consisting of [Pd(mu-Br)tBu3P]2 and NHC-indylidene ruthenium complexes, unsaturated compounds are continuously converted into equilibrium mixtures of double-bond isomers, which concurrently undergo catalytic olefin metathesis. Using such highly active catalyst systems, the isomerizing olefin metathesis becomes an efficient way to access defined distributions of unsaturated compounds from olefinic substrates. Computational models were designed to predict the outcome of such reactions. The synthetic utility of isomerizing metatheses is demonstrated by various new applications. Thus, the isomerizing self-metathesis of oleic and other fatty acids and esters provides olefins along with unsaturated mono- and dicarboxylates in distributions with adjustable widths. The cross-metathesis of two olefins with different chain lengths leads to regular distributions with a mean chain length that depends on the chain length of both starting materials and their ratio. The cross-metathesis of oleic acid with ethylene serves to access olefin blends with mean chain lengths below 18 carbons, while its analogous reaction with hex-3-enedioic acid gives unsaturated dicarboxylic acids with adjustable mean chain lengths as major products. Overall, the concept of isomerizing metatheses promises to open up new synthetic opportunities for the incorporation of oleochemicals as renewable feedstocks into the chemical value chain.

This paper describes effective photocurrent generation based on a polymer Langmuir-Blodgett (LB) monolayer containing ruthenium complex on a silver electrode excited by surface plasmon resonance (SPR). It was found that photocurrent generation is greatly enhanced at an incident angle where the electromagnetic field was most enhanced by SPR. At this angle, the photocurrent is enhanced by a factor of 23.6 compared with that at the critical angle for total internal reflection. The incident monochromatic photon-to-current conversion efficiency was 9.53*10-3 percent, higher than that of the corresponding polymer LB monolayer film on a transparent indium tin oxide electrode with conventional direct transmitted light (2.87*10-3 percent). Furthermore, it was demonstrated that precoating with poly(N-decylacrylamide) homopolymer ensures adequate separation of the Ru (bpy)3(2+) and silver surface, thereby suppressing the quenching of photoexcited Ru(bpy)3(2+) by the silver. Controlling the distance between the Ru(bpy)3(2+) layer and the silver using the Langmuir-Blodgett technique leads to effective photoexcitation of Ru(bpy)3(2+) by SPR and suppression of quenching by the silver surface, resulting in efficient photocurrent generation.

The reaction of various pyridine-2-carboxaldimine ligands with the [(eta6-arene)Ru(mu-Cl)Cl]2 dimer followed by a metathesis reaction with ammonium hexaflourophosphate, yielded the ruthenium(II) arene complex salts [(eta6-arene)RuCl(C5H4[Formula presented]6; where (arene = C6H6 (1), p-cymene (2), Ar = 3, 5-dimethyl phenyl (a), 2,3-dimethyl phenyl (b), 2,5-dimethyl phenyl (c), 3,4-dimethyl phenyl (d)). The compounds were characterized by elemental analysis, FT- IR, UV?vis and 1H and 13C NMR. Single crystal X-ray structures for compounds 1a, 1d and 2e were also determined and showed that the ruthenium(II) centre has a pseudo-octahedral geometry and the molecule adopted a three legged piano stool geometry in which the arene ring occupies the apex and the nitrogen atoms of the N,N?-bidentate ligand and the chloride atom the base of the stool. The Ru(II) complex salts were active for the catalytic transfer hydrogenation of ketones into alcohols in the presence of NaOH using 2-propanol as the hydrogen source at 82 C. The complexes were suitable for a wide range of aliphatic, cyclic and aromatic ketones giving good turn over numbers.

The complexes TpRu[P(OCH2)2(OCCH3] (PPh3)Cl (2) [Tp = hydridotris(pyrazolyl)borate; P(OCH 2)2(OCCH3) (1) = (4-methyl-2,6,7-trioxa-1- phosphabicyclo[2,2,1]heptane] and TpRu(L)(PPh3)Cl [L = P(OCH 2)3CEt (3), PMe3 (4) or P(OMe)3 (5)], (eta6-C6H6)Ru(L)Cl2 [L = PPh3 (6), P(OMe)3 (7), PMe3 (8), P(OCH 2)3CEt (9), CO (10) or P(OCH2) 2(OCCH3) (11)] and (eta6-p-cymene)Ru(L) Cl2 [L = P(OCH2)3CEt (12), P(OCH 2)2(OCCH3)P(OCH2) 2(OCCH3) (13), P(OMe)3 (14) or PPh3 (15)] have been synthesized, isolated, and characterized by NMR spectroscopy, cyclic voltammetry, mass spectrometry, and, for some complexes, single crystal X-ray diffraction. Data from cyclic voltammetry and solid-state structures have been used to compare the properties of (1) with other phosphorus-based ligands as well as carbon monoxide. Data from the solid-state structures of Ru(II) complexes show that P(OCH2)2(OCCH3) has a cone angle of 104. Cyclic voltammetry data reveal that the Ru(II) complexes bearing P(OCH2)2(OCCH3) have more positive Ru(III/II) redox potentials than analogous complexes with the other phosphorus ligands; however, the Ru(III/II) potential for (eta6-C 6H6)Ru[P(OCH2)2(OCCH 3)]Cl2 is more negative compared to the Ru(III/II) potential for the CO complex (eta6-C6H 6)Ru(CO)Cl2. For the Ru(II) complexes studied herein, these data are consistent with the overall donor ability of 1 being less than other common phosphines (e.g., PMe3 or PPh3) or phosphites [e.g., P(OCH2)3CEt or P(OMe)3] but greater than carbon monoxide.
