Titania-supported iridium subnanoclusters as an efficient heterogeneous catalyst for direct synthesis of quinolines from nitroarenes and aliphatic alcohols

A versatile heterogeneous catalyst consisting of sub-nanosized iridium clusters deposited on titania (Ir/TiO2-NCs) promotes the direct tandem synthesis of quinoline derivatives from readily available nitroarenes and aliphatic alcohols under mild and additive-free conditions (see scheme). The process tolerates the presence of various reactive functional groups and is highly selective.

Regiocontrolled Ru-catalyzed addition of carboxylic acids to alkynes: Practical protocols for the synthesis of vinyl esters

The catalytic activity of commercially available, air and water stable ruthenium complexes in the addition of carboxylic acids to terminal alkynes was found to be drastically enhanced by the addition of small quantities of base. Moreover, the regioselectivity of the reaction can be controlled by the choice of the base so that both the Markovnikov (Na2CO3) and the anti-Markovnikov products (DMAP) are now easily accessible in excellent selectivities.

Ruthenium(II) Charge-Transfer Sensitizers Containing 4,4?-Dicarboxy-2,2?-bipyridine. Synthesis, Properties, and Bonding Mode of Coordinated Thio- and Selenocyanates

The synthesis and properties of several complexes of Ru(II) containing 4,4?-dicarboxy-2,2?-bipyridine (dcbpyH2), 2,6-bis(1-methylbenzimidazol-2-yl)pyridine (bmipy), or 2,6-bis(1-methylbenzimidazol-2-yl)-4-phenylpyridine (phbmipy), and monodentate ligands (X- = Cl-, I-, NCS-, NCSe-, CN-) are reported. The introduction of the ambident ligands X- = NCS-, NCSe-, and CN- into the coordination sphere of [Ru(bmipy)(dcbpy)I]- and cis-Ru(dcbpyH2)2Cl2 has been studied in situ via 1H and 13C NMR spectroscopy using 13C-enriched ligands X-. Introduction of thiocyanate and selenocyanate initially yields the two possible linkage isomers in comparable amounts; prolonged reaction time converts the S-bound isomer and the Se-bound isomer to the N-bound isomers. The isoselenocyanate complex decomposes rapidly, yielding the cyano complex under loss of Se. The N-bound isothiocyanato complex K[Ru(bmipy)(dcbpy)(NCS)] was found to be an efficient sensitizer for nanocrystalline TiO2; the incident monochromatic photon-to-current efficiency (IPCE) is nearly quantitative at 520 nm. Introduction of a phenyl group in the 4-position of the 2,6-bis(1-methylbenzimidazol-2-yl)pyridine ligand gives a red-shifted absorption maximum for the corresponding phenylated K[Ru(ph-bmipy)(dcbpy)(NCS)] complex with an increased molar absorption coefficient for the MLCT maximum at 508 nm. At longer wavelengths above 620 nm, phenyl substitution does not enhance the absorption coefficients of the complex. Compared to that of K[Ru(bmipy)(dcbpy)(NCS)], the performance of the phenylated complex is reduced in a solar cell due to lower IPCE values. The visible spectra of the halide complexes K[Ru(bmipy)(dcbpy)X] (X- = Cl-, I-) show enhanced red response, but the complexes exhibit strongly reduced overall IPCE values. A comparison of the complexes to cis-Ru(dcbpyH2)2(NCS)2 is presented. Possible strategies for the design of more efficient sensitizers are discussed.

Photophysics and electron transfer in poly(3-octylthiophene) alternating with Ru(II)- and Os(II)-bipyridine complexes

A series of soluble metal – organic polymers that contain Ru(II) – and Os(II) – polypyridine complexes interspersed within a pi-conjugated poly(3-octylthiophene) backbone are prepared. Detailed electrochemical and photophysical studies are carried out on the polymers and two model complexes to determine the extent that the metal – polypyridine units interact with the pi-conjugated system. The results indicate that there is a strong electronic interaction between the metal-based chromophores and the pi-conjugated organic segments, and consequently the photophysical properties are not simply based on the sum of the properties of the individual components. In the Ru(II) polymers, the metal-to-ligand charge-transfer (MLCT) excited state is slightly higher in energy than the 3pi,pi* state of the poly(3-octylthiophene) backbone. This state ordering results in a material that displays only a weak MLCT luminescence and a long-lived transient absorption spectrum that is dominated by the 3pi,pi* state. In the Os(II) polymer the MLCT state is lower in energy than the polythiophene-based 3pi,pi* state and the “unperturbed” MLCT emission is observed. Finally, all of the metal-organic polymers undergo photoinduced bimolecular electron-transfer (ET) reactions with the oxidative quencher dimethyl viologen. Transient absorption spectroscopy reveals that photoinduced. ET to dimethyl viologen produces the oxidized polymers, and in most cases, the transient spectra are dominated by features characteristic of a poly(3-octylthiophene) polaron.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 10049-08-8 is helpful to your research., Reference of 10049-08-8

Heterooctanuclear Cluster Complex Formation with Phosphine Participation: Synthesis, Structure, and Magnetic Properties of Co6Ru2(mp)10(PBu3n) 6 (H2mp = 2-Mercaptophenol, PBu3n = Tri-n-butylphosphine)

The reaction of CoCl2, RuCl3, Na2(mp), and PBu3n (H2mp = 2-mercaptophenol, PBu3n = tri-n-butylphosphine) in ethanol in the molar ratio of 0.75:0.25:1:1 gave the complex Co6Ru2(mp)10(PBu3n) 6. The heterooctanuclear complex consists of six cobalt and two ruthenium ions chelated to as well as bridged by the 2-mercaptophenol ligands in a near-dimeric fashion with two mu2-OR groups bridging the two Co3Ru(mp)5(PBu3n)3 fragments without a crystallographic center of symmetry. Each fragment is formed by binding two of the Co(mp)2(PBu3n) structural units and one Co(mp) species to a central Ru(III) ion through the S donors of the five mp ligands, while the sixth coordination site of the octahedral Ru environment is completed by a phosphine ligand in the axial position. The Co6Ru2 moiety exhibits a zigzag assembly constructed by the mu2-O and mu2-S bridges of the bidentate 2-mercaptophenol ligands in a highly asymmetric fashion. The Co atoms are square pyramidally coordinated with apices that are occupied by the phosphine ligands or an oxygen atom from a mp2- ligand. Variable-temperature magnetic susceptibilities that were measured in the temperature range 300-1.6 K reveal that the spin cluster exhibits weak antiferromagnetic exchange interactions, A quantitative interpretation of the magnetic data was carried out by the irreducible tensor operator approach. Crystal data of the complex are as follows: triclinic space group P1, a = 14.931(3) A, b = 23.195(5) A, c = 24.259(5) A, alpha = 74.91(3), beta= 74.83(3), gamma = 78.80(3), and Z = 2.
