[Ru(R-bpy)2Cl2] is an important starting material for the synthesis of [Ru(N6)]2+ complexes. During the conventional synthesis procedure of [Ru(R-bpy)2Cl2], yield loss of up to 50% occurs, due to the formation of the side product [Ru(R-bpy)2(CO)Cl]+. The CO ligand hinders further conversion to [Ru(N6)]2+. Here we describe a simple and efficient removement of the CO ligand followed by a complexation of a third chelating ligand generating [Ru(N6)]2+. Complete removal of the CO ligand and formation of an intermediate state is verified by ESI-MS spectrometry and IR spectroscopy. After complexation of the third chelating ligand bpy, pure [Ru(R-bpy)3]2+ was formed with complete conversion. Purity of [Ru(R-bpy)3]2+ was ensured by IR-, NMR-spectroscopy and MS spectrometry.

Water oxidation catalysis by [(bpy)2(H2O)Ru-O-Ru(H2O)(bpy)2]4+ (Ru(III)(OH2)-O-Ru(III)(OH2)) complex was studied in a homogeneous aqueous solution (AS) as well as heterogeneous Nafion membrane (HM) using Ce(IV) oxidant. The initial O2 evolution rate, V(O2) (mol s-1) increased linearly at low complex concentrations under the excess Ce(IV) oxidant, showing that 4-electron water oxidation is catalyzed by one molecule of the complex. The intrinsic catalytic activities, k(O2) (s-1), in the AS and HM were 4.2 X 10-3 s-1 and 2.4 X 10-3 s-1, respectively. These values are much higher than those of well-known metal and metal oxide catalysts. Comparison of catalytic activity for various metal complexes and oxides is presented.

Electron transfer can readily occur over long (? 15 A) distances. Usually reaction rates decrease with increasing distance between donors and acceptors, but theory predicts a regime in which electron-transfer rates increase with increasing donor-acceptor separation. This counter-intuitive behavior can result from the interplay of reorganization energy and electronic coupling, but until now experimental studies have failed to provide unambiguous evidence for this effect. We report here on a homologous series of rigid rodlike donor-bridge-acceptor compounds in which the electron-transfer rate increases by a factor of 8 when the donor-acceptor distance is extended from 22.0 to 30.6 A, and then it decreases by a factor of 188 when the distance is increased further to 39.2 A. This effect has important implications for solar energy conversion.

You’ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology.15746-57-3, Name is Cis-Dichlorobis(2,2′-bipyridine)ruthenium(II), molecular formula is C20H16Cl2N4Ru. In a patent, introducing its new discovery.

Three tris(bidentate) monoruthenium complexes [Ru(dpma)(bpy)2](PF6)2 [1(PF6)2; dpma = di(pyrid-2-yl)(methyl)amine, bpy = 2,2?-bipyridine], [Ru(dpma)2(bpy)](PF6)2 [2(PF6)2], and [Ru(dpma)3](PF6)2 [3(PF6)2] with the electron-rich ligand dpma were synthesized and characterized. The single-crystal X-ray structures of 1(PF6)2 to 3(PF6)2 are presented. The electrochemical and spectroscopic properties of these complexes were examined and compared with those of the reference complex [Ru(bpy)3](PF6)2. Complexes 1(PF6)2 to 3(PF6)2 show a decreased RuIII/II redox potential by 140?310 mV with respect to [Ru(bpy)3](PF6)2. The strong emission property of [Ru(bpy)3](PF6)2 is maintained in 1(PF6)2 and 2(PF6)2. However, complex 3(PF6)2 is only weakly emissive at room temperature. In addition, density functional theory (DFT) and time-dependent DFT calculations were performed to complement these experimental results.

In a Article，once mentioned of 246047-72-3, Application In Synthesis of (1,3-Bis(2,4,6-trimethylphenyl)-2-imidazolidinylidene)dichloro(phenylmethylene)(tricyclohexylphosphine)ruthenium

cis-Dichloro-trans-dichloro isomerization was studied in sulfur-chelated ruthenium benzylidenes. The effect of solvents and additives on the isomerization process was analyzed. Notably, pi-acid ligand molecules, dichloromethane, and polar solvents were found to significantly accelerate the isomerization rate. As expected, the cis-trans isomer equilibria had a strong effect on the olefin metathesis reactivity; the bulkier cis-dichloro catalysts, which show a larger amount of trans isomer in the equilibrium, were more reactive than their less bulky counterparts. This tendency was generally reversed in the isolated trans isomer series, where both steric factors and faster isomerization play a role in dictating the olefin metathesis reactivity. A better understanding of the trans-cis isomerization and the mechanism that governs reactivity in strongly chelated cis-dichloro ruthenium benzylidenes was obtained.

The volatiles from the fungus Daldinia clavata were collected by use of a closed-loop stripping apparatus and analysed by GC-MS. A few compounds were readily identified by comparison of measured to library mass spectra and of retention indices to published data, while for other compounds a synthesis of references was required. For one of the main compounds, 5-hydroxy-4,6-dimethyloctan- 3-one, the relative and absolute configuration was determined by synthesis of all eight stereoisomers and gas chromatographic analysis using a homochiral stationary phase. Another identified new natural product is 6-nonyl-2H-pyran-2-one. The antimicrobial and cytotoxic effects of the synthetic volatiles are also reported.

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 301224-40-8 is helpful to your research., Electric Literature of 301224-40-8
