Ruthenium catalysts

The water-soluble ruthenium(II) complexes Na2[RuCpX-(mTPPMS) 2] [X = Cl (1), I (2)] and Nax[RuCp(mTPPMS)(PR 13)-(PR23)](OTf)y [PR13 = PR23 = PPh3 (3), PTA (4), x = y = 0; PR13 = mTPPMS, PR2 3 = PTA (5), x = 1, y = 0; PR13 = mTPPMS, PR23 = mPTA (6), x = y = 0; PR13 = PR23 = mTPPMS (7), x = 2, y = 0; PR1 3 = PPh3, PR23 = PTA (8), x = y = 0; PR13 = mPTA, PR23 = PPh3 (9), x = 0, y = 1; mTPPMS = Ph2P(3-OSO2C 6H4)-; PTA = 1,3,5-triaza-7-phosphaadamantane; mPTA = N-methyl-1,3,5-triaza-7-phosphaadamantane] have been synthesized and characterised by elemental analysis, NMR and IR spectroscopy and crystallographic methods. The X-ray crystal structure determination of [RuCp(mTPPMS)(PPh3)-(PTA)]·2H2O (8·2H 2O), which is the first half-sandwich ruthenium complex bearing three different phosphanes, has also been determined. The binding properties of these new water-soluble ruthenium complexes towards DNA and the interaction of free mTPPMS with the nucleic acid have been studied using the mobility shift assay, which has shown that both the activity of the ruthenium complexes and the possible mechanism governing the interaction with DNA are strictly dependent on the composition of the complexes.

Kinetic investigations on RuIII-catalysed oxidation of cycloheptanol by acidic solution of potassium bromate in the presence of mercuric acetate as a scavenger have been made in the temperature range 30-45 deg.The rate shows zero order kinetics both in bromate and hydrogen ions, but order of the reaction is two and one with respect to substrate and RuIII, respectively.Insignificant influence of chloride ions mercuric acetate and ionic strength of the medium was observed while the reaction showed negative dielectric effect.A transitient complex, formet between + and cyclopheptanol(+ being reactive species of ruthenium(III) chloride) in 1:2 ratio, disproportionates in a slow and rate-determining step to give reaction product and ruthenium(III) hydride which on interaction with acid bromate in a fast step regenerates catalytic species for recycling.Activation parameters have been calculated.

Radicicol (1) exhibits potent anticancer properties in vitro, which are likely to be mediated through its high affinity (20 nM) for the molecular chaperone Hsp90. Recently, we reported the results of a synthetic program targeting radicicol (1) and monocillin I (2), highlighted by the application of ring-closing metathesis to macrolide formation. These efforts resulted in a highly convergent synthesis of radicicol dimethyl ether but failed in the removal of the two aryl methyl ethers. Simple exchange of these methyl ethers with more labile functionalities disabled a key esterification in the initial route. Through extended experimentation, a successful route to both natural products was secured, along with some intriguing results that emphasize the implications of this design on a broad range of fused benzoaliphatic targets, including analogues of these natural products.

Ligand substitution of [(Ind)Ru(PPh3)2Cl] (1) led to the isolation of [(Ind)Ru(PPh3)(Ph2P(CH2) 2C9H7}Cl] (2), [(Ind)Ru(dppf)Cl] (3) and [(Ind)Ru{(Ph2PCH2)3CMe}]PF6 ([4]PF6), and diastereoisomers [(R)- and (S)-(Ind)Ru(Josiphos)Cl] [(R)-5 and (S)-5], where (R)-(S)-Josiphos is the ferrocene-based chiral diphosphane ligand (R)-(-)-1-[(S)-2-(diphenylphosphanyl)ferrocenyl] ethyldicyclohexylphosphane. The Cp analogues of 5, viz. (R)-6 and (S)-6, were also obtained from [CpRu(PPh3)2Cl] (1a). Josiphos-dependent epimerisation was observed, with conversion of the (S) isomer to the (R) isomer in both cases. Chloride abstraction of 3 with NaPF 6 in CH3CN and NaN3 in EtOH gave [(Ind)Ru(dppf)(CH3CN)]PF6 ([7]PF6) and [(Ind)Ru(dppf)(N3)] (8), respectively. The azido ligand in 8 underwent [3+2] dipolar cycloaddition with dimethyl acetylenedicarboxylate to give a N-bound bis-(methoxycarbonyl)-1,2,3-triazolato complex, 9. X-ray crystal structures of the new complexes, except (R)-5, (S)-5 and (S)-6, have been determined. Wiley-VCH Verlag GmbH & Co. KGaA, 2007.

We have prepared a novel Ru-mononer complex supported on a SiO2 surface by using a Rumonomer complex precursor with a p-cymene ligand, which was found to be highly active for the selective oxidation of aldehydes and the epoxidation of alkenes using O2. The structure of the supported Ru catalyst was characterized by means of FT-IR, solid-state NMR, diffuse-reflectance UV/vis, XPS, Ru K-edge EXAFS, and DFT calculations, which demonstrated the formation of isolatedly located, unsaturated Ru centers behind a p-cymene ligand of the Ru-complex precursor. The site-isolated Ru-monomer complex on SiO2 achieved tremendous TONs (turnover numbers) for the selective oxidation of aldehydes and alkenes; e.g. TONs of 38,800,000 for selective isobutyraldehyde (IBA) oxidation and 2,100,000 for trans-stilbene epoxidation at ambient temperature, which are among the highest TONs in metal-complex catalyzes to our knowledge. We also found that the IBA sole oxidation with an activation energy of 48 kJ mol-1 much more facile than the trans-stilbene epoxidation with an activation energy of 99 kJ mol -1 was completely suppressed by the coexistence of trans-stilbene. The switchover of the selective oxidation pathways from the IBA oxidation to the trans-stilbene epoxidation was explained in terms of energy profiles for the alternative selective oxidation pathways, resulting in the preferential coordination of trans-stilbene to the Ru-complex at the surface. This aspect gives an insight into the origin of the efficient catalysis for selective epoxidation of alkenes with IBA/O2.

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., Related Products of 10049-08-8

Phenol derivatives, which are one of the most important classes of aromatic compounds in organic chemistry, were synthesized by ruthenium-catalyzed ring-closing olefin metathesis (RCM) of 1,4,7-trien-3-ones with versatile substitution patterns. The RCM reaction for producing phenol derivatives was also successful with 1,5,7-trien-3-one as another precursor. Most of the phenols prepared here could not be obtained easily by conventional methods. Copyright

Analysis of the electronic structure of the electron-deficient cluster cation [Ru4(eta6-C6H6) 4H4]2+ (12+)by density functional theory calculations shows a very small energy gap (0.06 eV) between the diamagnetic singlet state and the paramagnetic triplet state, as a consequence of the absence of a significant Jahn-Teller distortion in the molecular structure of 12+. Magnetic measurements of [1]Cl2, [1][BF4]2, and [1][PF6]2 show 1 2+ to be diamagnetic in the fundamental state, with some weak temperature-independent paramagnetism, depending upon the nature of the counterion.
