Carbonyl-containing Ru and Fe heterobimetallic complexes were prepared and tested as electrocatalysts for the oxidation of methanol and ethanol. GC analysis of the electrolyte solution during bulk electrolysis indicated that CpRu(CO) (mu-I) (mu-dppm) PtI2 (1), CpFe(CO) (mu-I) (mu-dppm) -PtI2 (2), and CpRu(CO) (mu-I) (mu-dppm) PdI2 (3) were catalysts for the electrooxidation of methanol and ethanol, while CpFe(CO) (mu-I) (mu-dppm) -PdI2 (4), CpRu(CO) I(mu-dppm) AuI (5), and CpFe(CO) I(mu-dppm) AuI (6) did not function as catalysts. The oxidation of methanol resulted in two-and four-electron oxidation to formaldehyde and formic acid, respectively, followed by condensation with unreacted methanol to yield dimethoxymethane and methyl formate as the observed products. The oxidation of ethanol afforded 1, 1 – diethoxyethane as a result of two-electron oxidation to acetaldehyde and condensation with excess ethanol. FTIR analysis of the headspace gases during the electrochemical oxidation of methanol indicated formation of CO2. Isotopic labeling experiments demonstrated that the CO2 resulted from oxidation of the CO ligand instead of complete oxidation of CH3OH.

The complexes [PdCl2(L1/L2)] (1/7), [PtCl2(L1/L2)] (2/8), [RuCl(eta6-C6H6)(L1/L2)][PF6] (3/9), [RuCl(eta6-p-cymene)(L1/L2)][PF6] (4/10), [RuCl(eta6-p-cymene)(NH3)2][PF6] (5) and [Ru(eta6-p-cymene)(L1)(CH3CN)][PF6]2·CH3CN (6) have been synthesized. The L1-L3 and complexes were found to give characteristic NMR (Proton, Carbon-13 and Se-77). The crystal structures of complexes 1, 3-6, 9 and 10 have been solved. The Pd-Se and Ru-Se bond lengths have been found to be 2.353(2) and 2.480(11)/2.4918(9)/2.4770(5) A?, respectively. The complexes 1 and 7 have been explored for catalytic Heck and Suzuki-Miyaura coupling reactions. The value of TON has been found up to 85 000 with the advantage of catalyst’s stability under ambient conditions. The efficiency of 1 is marginally better than 7. The Ru-complexes 3 and 9 are good for catalytic oxidation of primary and secondary alcohols in CH2Cl2 in the presence of N-methylmorpholine-N-oxide (NMO). The TON value varies between 8.0 × 104 and 9.7 × 104 for this oxidation. The 3 is somewhat more efficient catalyst than 9.

The ligand [2-chloro-3-(3-(2-pyridyl)pyrazolyl)quinoxaline] (L) have been prepared from 2,3-dichloroquinoxaline and 3-(2-pyridyl)-1H-pyrazole. The reaction of N,N?-bidentate chelating ligand (L) and the corresponding metal precursors [(arene)Ru(mu-Cl)Cl]2 {arene = p-cymene, benzene, hexamethylbenzene (HMB)}, [Cp?M(mu-Cl)Cl]2 {Cp? = pentamethylcyclopentadiene; M = Rh, Ir}, [CpRuCl(PPh3)2] {Cp = cyclopentadiene; PPh3 = triphenylphosphine} and [Re(CO)5Br] leads to the formation of mononuclear metal complexes having the general formula [(arene)Ru(L)Cl]+ where, arene = p-cymene (1), C6H6 (2), C6Me6 (3), [Cp?M(L)Cl]+ where, M = Rh (4), Ir (5), [CpRu(L)PPh3]+ (6) and [Re(L)(CO)3Br] (7). All these platinum group metal complexes were synthesized and isolated with PF6 counter anions except complex (6) whereas the complex (7) was isolated as a neutral complex. All these metal complexes were fully characterized by FT-IR, 1H NMR, UV-Vis and mass spectroscopic and analytical techniques. Moreover, the complexes (1-7) were determined by the single-crystal X-ray diffraction analysis. Single crystal X-ray data confirms that the coordination occurs to the N-atoms of the pyridyl and pyrazolyl moieties of the ligand. Agar well diffusion method reveals that complexes (1, 2, 4 and 5) are having good antibacterial activity against the three different bacteria, pathogenic test organisms Staphylococcus aureus subsp. aureus, Staphylococcus epidermidis and Escherichia coli. The electronic transitions and absorption band of the complexes calculated by using time-dependent DFT method are in good agreement with the experimental results.

Application of 246047-72-3, 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.246047-72-3, Name is (1,3-Bis(2,4,6-trimethylphenyl)-2-imidazolidinylidene)dichloro(phenylmethylene)(tricyclohexylphosphine)ruthenium, molecular formula is C46H65Cl2N2PRu. In a patent, introducing its new discovery.

In this contribution, we study the conversion of a bio-sourced unsaturated fatty ester by cross-metathesis with nitrile-functionalized olefinic partners (acrylonitrile and crotonitrile). A switch from terminal to internal olefins leads to higher conversion. This is in part rationalized by involvement of a more stable ruthenium ethylidene species with crotonitrile. A new carbenic complex forms upon reaction with the nitrile-functionalized olefins, that is also catalytically active.

New ionophilic Hoveyda-type complexes were prepared by the treatment of Grubbs’ second-generation catalyst with the readily obtained 2,3-dimethyl-1-[1-methyl-3-(2-vinylphenoxy)butyl]-imidazolium hexafluorophosphate ligand, for example. This new carbene complex immobilized in BMI · PF6 ionic liquid presents excellent catalytic activities in 1,7-octadiene, diallyl diethylmalonate, and allylmethallyl dimethylmalonate ring-closing metathesis (RCM) reactions. The ionophilic complex can be recycled up to seven times in the 1,7-octadiene RCM reaction. The structure of this complex has been unambiguously established by NMR and single-crystal X-ray diffraction studies.

A chloride anion templation methodology is utilized in the construction of novel transition-metal rhenium(I) and ruthenium(II) bipyridyl appended [2]rotaxanes. 1H NMR spectroscopic titrations reveal the ability of the rotaxanes to selectively bind chloride over the more basic oxoanions, with the ruthenium(II) bipyridyl appended rotaxane strongly binding chloride in 30 % water. Photophysical investigations demonstrate the ability of the rotaxanes to sense anions in aqueous media, with chloride being selectively complexed, in general agreement with NMR spectroscopy determined anion binding data. Chloride anion templation is used to synthesise novel rhenium(I) and ruthenium(II) bipyridyl appended [2]rotaxanes (see figure). 1H NMR spectroscopic titrations reveal the rotaxanes are capable of binding anions in competitive aqueous solvent mixtures, with the ruthenium rotaxane strongly complexing chloride in 30 % water.
