The Cp(PPh3)2Ru-nCR=CH2 complexes 2 – 4 (n = 0, 2, R = H; n = 3, R = CH3) are prepared by treatment of the chloride 1 with the appropriate organomagnesium halides.The vinyl complex 2 eliminates a PPh3 ligand above 100 deg C and reacts with ethylene (20 – 30 bar) by insertion into the Ru – vinyl bond to give the (eta3-1-methylallyl)ruthenium complex 6a.The 3- and 4-alkenyl compounds 3 and 4 isomerize at 80 – 100 deg C after dissociation of one PPh3 via an (eta2-alkadiene)hydridoruthenium intermediate, e.g. 7, to form the eta3-allyl complexes 6, 8, and 9, respectively.The stable (eta1,eta2-4-alkenyl)ruthenium compounds 10 – 12 are formed if isomerization by beta-H-elimination is prevented by E-configuration of Ru and beta-H in a conformatively inflexible cyclopropyl system.The 31P chemical shifts of 2 – 4 and the (eta1-allyl)ruthenium complexes, of 10 – 12, and of the eta3-allyl complexes 6a, 8, 9, 13a are characteristic for the corresponding type of compounds.

Photoinduced intramolecular electron transfers within ligand-bridged Ru(II) and Co(III) compounds of <(bpy)2Ru(L)Co(bpy)2>(5+) (a, b, and c) were examined in butyronitrile by means of laser photolysis kinetic spectroscopy, where L is a bridging tetradentate ligand, 2,6-bis(2-pyridyl)benzodiimidazole for a, 2,2′-bis(2-pyridyl)bibenzimidazole for b, and 1,5-bis<2-(2-pyridyl)benzimidazoyl>pentane for c.The temperature dependence of the rates of electron transfer and intersystem crossing is analyzed by taking the temperature dependence of the Gibbs energy change and reorganization energy into account.A transient difference absorption band at 420 nm observed after the picosecond laser excitation of a and b is not ascribed to the formation of excited Ru(II) moiety but to the reaction product (2Co(II)) of the Co(III) moiety, which decayed to form a long-lived species of 4Co(II) within 1 ns below 270 K.The inner-sphere reorganization of the intersystem crossing of 2Co(II) -> 4Co(II) is estimated to be 0.6 eV from the temperature dependence of the transition rate.The electron transfer from the excited MLCT state of the Ru(II) moiety to Co(III) for c occured within 1 ns at 300 K.The inner-sphere reorganization energy (0.6 eV) of the electron transfer was determined from the temperature-dependent electron transfer rate observed.The back electron transfer from 4Co(II) to 2Ru(III) was much slower than the initial electron transfer.It is not the small electronic coupling between 4Co(II) and 2Ru(III) but the negative entropy change (-1.3 meV/K) of Co(II) oxidation that is responsible for the small frequency factor of the electron transfer process.The inner-sphere organization energy of the back electron transfer was determined (1.1-1.3 eV) from the temperature-dependent rate.

The molecular building blocks Fe(II)Pc (Pc = phthalocyaninato2-), Fe(III)Pc, ZnPc, Cp(dppe)Fe, and Cp(PPh3)2Ru were combined in the cyanide-bridged dinuclear reference compounds with M-CN-ZnPc and M-CN-FePc-CN arrays containing Fe(II)Pc and Fe(III)Pc. The linear trinuclear species with the M(mu-CN)Fe(mu-CN)M’ backbone were prepared for both Fe(II)Pc and Fe(III)Pc centers, for terminal Fe/Fe, Fe/Ru, and Ru/Ru combinations and for all three possible cyanide orientations (M-CN-Fe-NC-M’, M-CN-Fe-CN-M’, and M-NC-Fe-CN-M’). The 15 complexes obtained were identified from their IR spectra and six structure determinations. The preferred orientation of the cyanide bridges could be established starting from the [Fe-NC-Fe(III)Pc-CN-Fe]+ complex, which is labile in solution and isomerizes to the corresponding [Fe-CN-Fe(III)Pc-NC-Fe]+ complex. A kinetic analysis of this isomerization has yielded an activation barrier of roughly 110 kJ/mol.

The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.10049-08-8, Name is Ruthenium(III) chloride, molecular formula is Cl3Ru. In a Article，once mentioned of 10049-08-8, Computed Properties of Cl3Ru

A new series of mono and binuclear Mn(II), Fe(III), Co(II), Ni(II), Cu(II), Zn(II), La(III), Ru(III), Hf(IV), ZrO(II) and UO2(II) complexes of phenylaminodibenzoylhydrazone have been synthesized and characterized by elementals analyses, IR UV-vis spectra, magnetic moments, conductances, thermal analyses (DTA and TGA) and electron spin resonance (ESR) measurements. The IR spectral data show that, the ligand behaves as a neutral bidentate type (15 and 16), monobasic bidentate type (6), or monobasic tridentate type (5, 7, 8, 10, 11, 13, 14, 17-21) or dibasic tridentate type 2-4, 9 and 12 towards the metal ion. Molar conductances in DMF solution indicate that, the complexes are non-electrolytes. The ESR spectra of solid complexes (9 and 10) show axial and non-axial types indicating a d(x2 – y2) ground state with significant covalent bond character. However, complexes (11 and 12), show isotropic type, indicating manganese(II) octahedral geometry. Antibacterial and antifungal tests of the ligand and its metal complexes are also carried out and it has been observed that the complexes are more potent bactericides and fungicides than the ligand.

Cyclic Ru-phenolates were synthesized, and these compounds were used as olefin metathesis catalysts. Investigation of their catalytic activity pointed out that, after activation with chemical agents, these catalysts promote ring-closing metathesis (RCM), enyne and cross-metathesis (CM) reactions, including butenolysis, with good results. Importantly, these latent catalysts are soluble in neat dicyclopentadiene (DCPD) and show good applicability in ring-opening metathesis polymeriyation (ROMP) of this monomer. Olefin metathesis catalysis: Investigation of the catalytic activity of Ru phenolate catalysts pointed out that, after activation with chemical agents, these catalysts promote ring-closing metathesis (RCM), enyne, and cross-metathesis (CM) reactions, including butenolysis, with good results (see scheme, Mes=2,4,6-trimethylphenyl, Cy=cyclohexyl).

Application of 37366-09-9, An article , which mentions 37366-09-9, molecular formula is C12H12Cl4Ru2. The compound – Dichloro(benzene)ruthenium(II) dimer played an important role in people’s production and life.

The trinuclear arene-ruthenium cluster cations [H3Ru 3(C6H6)(C6H2Me 4)2(O)]+ (2) and [H3Ru 3{C6H5(CH2)2OH}(C 6H2Me4)2(O)]+ (3) have been synthesised from the dinuclear precursor [H3Ru 2(C6H2Me4)2]+ (1) and the mononuclear complexes [Ru(C6H6)(H 2O)3]2+ and [Ru{C6H 5(CH2)2OH}(H2O)3] 2+, isolated and characterised as the tetrafluoroborate salts. Cations 2 and 3 are analogues of the cluster cation [H3Ru 3(C6H6)(C6Me6) 2(O)]+ which was found to catalyse the hydrogenation of benzene to give cyclohexane under biphasic conditions (‘supramolecular cluster catalysis’). The single-crystal X-ray structure analyses of 2 and 3 have been determined. Unlike [2][BF4]·3H2O, [3][PF 6]·H2O shows a dimeric structure in the solid state, thanks to hydrogen bonds between the hydroxo function of one molecule of 3, a water molecule and the oxo cap of an other molecule of 3.

We demonstrated a novel approach to produce robust bicontinuous nanoporous polymer membranes by ring-opening metathesis polymerization of a new norbornene-functional diblock copolymer and dicyclopentadiene followed by selective removal of a chemically etchable polylactide block. Polymerization-induced phase separation from the initial homogeneous tetrahydrofuran solution of all components led to a disordered but cocontinuous structure in the resulting cross-linked plastics. After polylactide removal, the nanoporous (ca. 20 nm pores) membranes exhibited excellent thermal stability and mechanical toughness, high specific surface areas, narrow pore size distributions, and good permeability.
