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.

[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.

You’ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology.37366-09-9, Name is Dichloro(benzene)ruthenium(II) dimer, molecular formula is C12H12Cl4Ru2. In a patent, introducing its new discovery.

An important objective for the discovery of compounds with unique biological activities is the development of methods for the synthesis of molecular scaffolds with defined three-dimensional shapes. We are currently investigating the scope of using metal complexes to accomplish this goal. In these compounds, the metal center has the role of organizing the orientation of the organic ligands, thus defining the overall shape of the molecule. A strategy is presented that allows a rapid scanning of ligands around a ruthenium center in the search for ligand spheres that are complementary in shape and functional group presentation to ATP binding sites of protein kinases. Following this approach, we have identified octahedral ruthenium complexes as potent inhibitors for the protein kinases Pim1, MSK1, and GSKSalpha.

We report the first synthesis of p-bonded rhodio and iridio-o-benzoquinones [Cp*M(o-benzoquinone)] (M = Rh (3a); M = Ir (3b)) following a novel synthetic procedure. These compounds were fully characterized by spectroscopic methods; in particular the X-ray molecular structure of 3b was determined. Compounds 3a,b were used as chelating organometallic linkers for the design of a new family of chiral octahedral bimetallic complexes, 4-9. The X-ray molecular structure of [(bpy)2Ru(3b)][OTf]2 (5) is presented and shows that the organometallic linker 3b is chelating the ruthenium center. In particular, the carbocycle of the organometallic linker 3b adopts a n4-quinone form, where the Cp*Ir is also bonded to only four carbons. Further our strategy to design new assemblies with organometallic linkers is successfully achieved. These assemblies hold promise for new properties relative to those made from organic bidentate ligands.

[RuCl2(CO)3]2/dppp is shown to be a highly effective catalyst system for the first intramolecular oxidative amination of a variety of aminoalkenes when it is used concomitantly with K2CO3 and allyl acetate in N-methylpiperidine, to give the corresponding cyclic imines and indoles in excellent yields. For example, the reaction of 2,2-diphenyl-4-pentenyl-1-amine performed in the presence of 2 mol % of [RuCl2(CO)3]2, 4 mol % of dppp, K2CO3, and allyl acetate in N-methylpiperidine at 140 C for 8 h gives 4,4-diphenyl-2-methyl-1-pyrroline in quantitative (>99%) yield.

In order to gain a deeper mechanistic understanding of water oxidation by [(bda)Ru(L)2] catalysts (bdaH2 = [2,2?-bipyridine]-6,6?-dicarboxylic acid; L = pyridine-type ligand), a series of modified catalysts with one and two trifluoromethyl groups in the 4 position of the bda2- ligand was synthesized and studied using stopped-flow kinetics. The additional -CF3 groups increased the oxidation potentials for the catalysts and enhanced the rate of electrocatalytic water oxidation at low pH. Stopped-flow measurements of cerium(IV)-driven water oxidation at pH 1 revealed two distinct kinetic regimes depending on catalyst concentration. At relatively high catalyst concentration (ca. ?10-4 M), the rate-determining step (RDS) was a proton-coupled oxidation of the catalyst by cerium(IV) with direct kinetic isotope effects (KIE > 1). At low catalyst concentration (ca. ?10-6 M), the RDS was a bimolecular step with kH/kD ? 0.8. The results support a catalytic mechanism involving coupling of two catalyst molecules. The rate constants for both RDSs were determined for all six catalysts studied. The presence of -CF3 groups had inverse effects on the two steps, with the oxidation step being fastest for the unsubstituted complexes and the bimolecular step being faster for the most electron-deficient complexes. Though the axial ligands studied here did not significantly affect the oxidation potentials of the catalysts, the nature of the ligand was found to be important not only in the bimolecular step but also in facilitating electron transfer from the metal center to the sacrificial oxidant.
