Selective linear coupling reaction of acetylene and acrylonitrile catalyzed by the well-defined metallacyclopentadiene complex C5Me5(PPh3)(Cl)RuCH=CHCH=CH

The metallacyclopentadiene complex C5Me5(PPh3)(Cl)RuCH=CHCH=CH (1) was found to catalyze the linear coupling reaction of acetylene and acrylonitrile to give predominantly 2(E),4(Z),6-heptatrienenitrile (3; TON = 15, 85% selectivity). The coupling reaction is proposed to occur via an initial PPh3 dissociation from 1 and the subsequent insertion of acrylonitrile.

Tandem isomerisation-metathesis catalytic processes of linear olefins in ionic liquid biphasic system

trans-3-Hexene is converted to heavier linear olefins by a tandem Ru-catalysed biphasic isomerisation/metathesis sequence. The difference in olefin metathesis and isomerisation rates is modulated by keeping the ionophilic metathesis catalyst in an ionic phase whilst the isomerisation catalyst is in another organic non-polar phase.

Organometallic ruthenium(II) scorpionate as topo IIalpha inhibitor; In vitro binding studies with DNA, HPLC analysis and its anticancer activity

New organoruthenium [(eta6-arene)RuII(L)Cl]Cl (1: arene = p-cymene, L = L1; 2: arene = p-cymene, L = L2; 3: arene = benzene, L = L1; 4: arene = benzene; L = L2; L1 = bis(3,5-dimethylpyrazolyl)parabenzoic acid, L2 = bis(3,5-dimethylpyrazolyl)metabenzoic acid) have been synthesized and characterized by analytical and spectroscopic methods. The molecular structure of [(eta6-p-cymene)RuCl(L1)]Cl (1) was determined by single crystal X-ray diffraction studies. Preliminary in vitro binding studies of 1-4 with CT DNA were carried out by employing various biophysical techniques which revealed their avid DNA binding via non-covalent binding mode viz; partial intercalation of the eta6-arene group as well as electrostatic surface interaction through one oxygen atom of the phosphate backbone of the DNA helix; however, complexes 1 and 3 display higher binding propensity in comparison to 2 and 4, as quantified by Kb. The interaction was further analysed by HPLC technique. The results of the cleavage experiments of pBR322 DNA with 1 and 3 displayed significantly good cleavage at 20-40 muM, following the oxidative pathway. These findings have revealed that the hydrophobic arene, and the chloride leaving group have important roles in the novel mechanism of recognition of DNA by (eta6-arene)ruthenium(II) complexes, and will aid the design of more effective anticancer complexes, as well as new site-specific DNA reagents. Furthermore, the anticancer activity of the complexes 1 and 3 on 15 cell lines of different histological origin has been studied. It has been observed that 1 exhibits higher cytotoxicity than 3, and the cells undergo apoptotic cell death.

Synthesis and characterization of novel oxime-imine ligands and their heteronuclear ruthenium(III) complexes

Vicinal carbonyl oxime (HL1) and oxime-imine (H 2L2) ligands and their mononuclear Ru(III) and Cu(II), heterodinuclear Ru(III)-Mn(II), Ru(III)-Ni(II), Ru(III)-Cu(II), and heterotrinuclear Ru(III)-Cu(II)-Ru(III) chelates were synthesized and characterized by elemental analysis, molar conductivity, IR, ESR, ICP-OES, magnetic moment measurements, and thermal analyses studies. The free ligands were also characterized by 1H NMR spectra. The carbonyl-oxime ligand coordinates through the oxygen of =N-OH to form a six-membered chelate ring. The quadridentate tetraaza ligand (H2L2) obtained by condensing of the bidentate ligand 1-p-diphenylmethane-2-hydroxyimino-2-(1- naphthylamino)-1-ethanone (HL1) with 1,2-phenylenediamine coordinates with Ru(III) through its nitrogen donors in the equatorial position with the loss of one of the oxime protons and concomitant formation of an intramolecular hydrogen bond. Stoichiometric and spectral results of the metal complexes indicated that the metal: ligand ratios in the mononuclear complexes of the ligand (HL1) were found to be 1: 2, while these ratios were 1: 1 in the mononuclear complexes of the ligand (H2L2). The metal: ligand ratios of the dinuclear complexes were found to be 2: 1, and this ratio was 3: 2 in the trinuclear complex.

Conversion of Coordinated Carbon Monoxide into Carbon Dioxide via Oxygen-atom transfer from Coordinated Nitrite: Thermolysis of Ru(NO2)2(CO)2(PPh3)2

The thermolysis (111 deg C, toluene solution) of Ru(NO2)2(CO)2(PPh3)2 in the presence of excess PPh3 procced according to the stoichiometry Ru(NO2)2(CO)2(PPh3)2 + PPh3 -> Ru(NO2)2(PPh3)2 + CO2 + CO + Ph3PO.Two highly selective oxygen-atom transfer processes are involved in the overall thermolysis reaction: (i) Ru(NO2)2(CO)2(PPh3)2 -> Ru(ONO)(CO)(NO)(PPh3)2 + CO2; (ii) Ru(ONO)(CO)(NO)(PPh3)2 + PPh3 -> Ru(NO2)2(PPh3)2 + CO + Ph3PO.The intermediate complex Ru(ONO)(CO)(NO)(PPh3)2 was synthesized independently and has been characterized by analytical and spectral methods.The thermolysis of Ru(N18O2)2(CO)2(PPh3)2 unambiguosly establishes coordinated NO2- as the source of oxygen in the conversion of coordinated CO into CO2.Moreover, the extent of 18O enrichment in the CO2 product indicates that statistical scrambling of oxygen occurs between nitrogen and carbon atoms prior to the loss of CO2.The results of a double-label study involving the thermolysis of Ru(N18O2)2(CO)2(PPh3)2 and Ru(NO2)2(13CO2)2 are consistent with an intermolecular mechanism for oxygen-atom transfer from NO2- to CO.Additional mechanistic implications are described.

Reversible hydride generation and release from the ligand of [Ru(pbn)(bpy)2](PF6)2 driven by a pbn-localized redox reaction

(Chemical Equation Presented) Electrochemical reduction of [Ru(pbn)-(bpy)2]2+ (1, pbn = 2-(2-pyridyl)benzo[b]-1,5- naphthyridine, bpy = 2,2?-bipyridine) in an acidic solvent gives [Ru(pbnH2)-(bpy)2]2+ (2), which releases the hydrogen as “hydride” (see scheme). This catalytic system reduces substrates (for example, acetone) with two electrons and protons from water, and thus operates in a similar way to the NAD+/NADH redox couple.

Preparation of chiral imidazolin-2-imine ligands and their application in ruthenium-catalyzed transfer hydrogenation

2-Chloro-1,3-diisopropyl-4,5-dimethylimidazolium tetrafluoroborate (1) serves as a convenient starting material for the preparation of mono- and bis(imidazolin-2-imine) ligands. Thus, the reaction of two equivalents of 1 with 1,2-ethylenediamine in the presence of potassium fluoride afforded the bis(2-aminoimidazolium) salt [BLiPrH2][BF4]2 (2), from which the achiral bis(imidazolin-2-imine) ligand N,N?-bis(1,3-diisopropyl-4,5-dimethylimidazolin-2-ylidene)-1,2-ethanediamine (BLiPr) can be obtained by deprotonation. Likewise, the reaction of 1 with (1R,2R)-(-)-1,2-diaminocyclohexane (DACH) gave [DACH(ImiPrH)2][BF4]2 (3) and its deprotonation the chiral, C2-symmetric diimine DACH(ImiPr)2 (4). Under similar conditions, chiral, C1-symmetric mono(imidazolin-2-imines) were obtained from the reaction of 1 with one equivalent of (1R,2R)-(-)-1,2-diaminocyclohexane (DACH) or (1S,2S)-(-)-1,2-diphenylethylenediamine (DPEN), which afforded the 2-aminoimidazolium salts [DACH(ImiPrH)NH2][BF4] (5) and [DPEN(ImiPrH)NH2][BF4] (6), respectively. The reaction of 4 with [(C6H6)RuCl2]2 gave ruthenium complex [(C6H6)Ru{DACH(ImiPr)2}]Cl2, [7]Cl2, which was treated with KPF6 to form [7][PF6]2. The ligand precursors 5 and 6 were deprotonated in the presence of [(C6H6)RuCl2]2, which resulted in the formation of complexes [(C6H6)Ru{DACH(ImiPr)NH2}Cl]Cl [8]Cl and [(C6H6)Ru{DPEN(ImiPr)NH2}Cl]Cl [9]Cl. Complexes [7][PF6]2, [8]Cl and [9]Cl were investigated for their ability to catalyze the transfer hydrogenation of acetophenone in isopropanol. Complex [8]Cl proved to be the most active system, while complex [9]Cl produced the highest enantioselectivity, albeit of only 27% ee. The molecular structures of [7][(C6H6)RuCl3]2¡¤CH2Cl2, formed as a side product, and of [8]Cl¡¤acetone were determined by X-ray diffraction analyses.

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 37366-09-9 is helpful to your research., Synthetic Route of 37366-09-9

Ruthenium(III)-catalyzed oxidation of 2-phenylethylamine with sodium N-chlorobenzenesulphonamide in hydrochloric acid solution: A kinetic and mechanistic study

The kinetics of ruthenium(III)-catalyzed oxidation of 2-phenylethylamine (PEA) with sodium N-chlorobenzenesulphonamide or chloramine-B (CAB) in hydrochloric acid solution has been studied at 313 K. The reaction rate shows first-order dependence each on [CAB], [H+] and [Ru(III)Cl3] and fractional order on [PEA] and [Cl-]. Variation of ionic strength and addition of the reduction product of CAB has no significant effect on the rate. There is a negative effect of dielectric constant of the solvent. The stoichiometry of the reaction was found to be 1:1 and the oxidation product of 2-phenylethylamine was identified as phenyl acetaldehyde. The reaction was studied at different temperatures and the activation parameters have been evaluated from the Arrhenius plot. The reaction constants involved in the mechanisms were computed. RN+H2Cl has been postulated as the reactive oxidizing species. Mechanisms consistent with the observed kinetic data have been proposed and discussed.
