Complexes of general formula (eta5-L)RuCl(PR3)2 are shown to be active and highly selective catalysts for the olefination of aldehydes in the presence of phosphines and diazoacetate at moderate temperatures. With equal catalyst loadings of Cp*RuCl(PR3) 2 shows comparable activity and higher selectivity with regard to the most active catalysts known to date for this reaction. Spectroscopic investigations demonstrate that the reaction mechanism includes the quantitative formation of the corresponding phosphorus ylide from the preformed phosphazine.

This paper reports preparation of new silyl hydride complexes of ruthenium supported by the Cp/PR3 ligand set. It is shown that the easiest and most general route to these complexes is provided by the thermal reaction of [RuCp(PR3)(H)3] with hydrosilanes. Complexes [RuCp(PR 3)(H)2(SiMe2Cl)] exhibit Interligand Hypervalent Interactions (IHI) between the hydride and silyl ligands. Comparison of the X-ray structures of complexes [RuCp(PPri3)(H) 2(SiMe2Cl)], [RuCp(PPhPri2)(H) 2(SiMe2Cl)], and [RuCp(PPh3)(H) 2(SiMe2Cl)] shows that the IHI weakens with the decreasing electron-releasing ability of the phosphine. Comparison of the X-ray structure of [RuCp(PPh3)(H)2(SiMe2Cl)] with the structure of the previously reported complex [RuCp*(PPh3)(H) 2(SiMe2Cl)] reveals that the lack of IHI in the latter compound is due to unfavourable steric interactions between the bulkier Cp* ring and the SiMe2Cl group.

32993-05-8, Name is Chlorocyclopentadienylbis(triphenylphosphine)ruthenium(II), molecular formula is C41H35ClP2Ru, belongs to ruthenium-catalysts compound, is a common compound. In a patnet, once mentioned the new application about 32993-05-8, HPLC of Formula: C41H35ClP2Ru

New phosphoramidite complexes of ruthenium chiral at the metal were synthesized, structurally characterized and their electrochemical and catalytic properties were studied. Reaction of the known chiral phosphoramidites (RO)2 PNR2? (R = naphthyl, R? = CH3, 1a; R = naphthyl, R? = benzyl, 1b; R = octahydronaphthyl, R? = benzyl, 1c) with CpRu(PPh3)2Cl afforded the title compounds CpRu(PPh3)(1a-c)(Cl) (2a-c) in 46-74% isolated yields. Fractional crystallization of 2b and 2c afforded the corresponding diastereopure complexes which are chiral both at the metal and at the ligand. The molecular structures of 2b and 2c were determined, revealing a pseudo octahedral coordination geometry about the ruthenium center. Electrochemical studies by cyclic voltammetry showed reversible electrochemical behavior of the metal complexes 2a-c. The new metal complexes are catalytically active in the Mukaiyama aldol reaction (24 h, room temperature, 31-53% yield), but almost no enantiomeric excesses for the products were obtained.

The syntheses of the alkyne (E)-4,4?-HCCC6H4N=NC6H4NO 2 (1) and alkynyl complexes LnM{(E)-4,4?-CCC6H4N=NC6H 4NO2} [LnM=trans-[RuCl(dppm)2] (2), Ru(PPh3)2(eta-C5H5) (3), Au(PPh3) (4)] are reported. A structural study of 2 reveals E stereochemistry about the azo-linkage. Electrochemical data for the ruthenium complexes reveal that the azo-linkage in complexes 2 and 3 perturbs the metal-centred oxidation potential compared to all other alkynyl complexes of similar composition. Quadratic optical nonlinearities by hyper-Rayleigh scattering (HRS) at 1064 nm are very large for 2 and 3, but resonance-enhanced. Comparison of HRS data for 4 with those of Au{(E)-4,4?-CCC6H4X=CHC6H 4NO2}(PPh3) (X=CH, N) reveals that complex 4 has a significantly larger quadratic nonlinearity than its ene- or imino-linked analogues.

A nucleic acid base derivative tethered to a ruthenium carbene complex: hydrogen bonded dimers in both the solid state and solution?

A ruthenium carbene bearing a uracil (Ur) substituent has been prepared and has a dimeric structure in the solid state-the dimer being held together by hydrogen bonds between two uracil groups on neighbouring molecules: evidence for the persistence of this interaction in solution has been obtained.

Acid-promoted hydrogen migration in (2-allylphenoxo)ruthenium(II) to form an eta3-allyl complex

Treatment of RuCP[OC6H4(CH2CH=CH 2)-kappa1O: eta2C,C?](PPh 3) (3c) with a Bronsted acid (HX) such as 2-al-lylphenol results in facile migration of a benzylic proton to the aryloxide, giving the (eta3-allyl)ruthenium(II) complex RuCp[CH2-CHCH(C 6H4OH-2)-eta3 C,C?,C?](PPh 3) (Ac). Thermodynamic and kinetic studies suggest that 3c associates with acid to give 3c · HX, and further addition of HX to 3c · HX causes the C-H bond cleavage reaction to give 4c.

Synthesis and structural characterization of some selenoruthenates and telluroruthenates

The reaction of solid [RuClCp(PPh3)2] with TeSe 32- or Sen2- in DMF leads to the formation of [RuCp(PPh3)(mu2-Se2)] 2 (1). In the structure of this compound the two bridging Se 2 groups lead to a six-membered Ru2Se4 ring in a chair conformation. Attached to each Ru center is a PPh3 ligand in an equatorial position and a Cp ring in an axial position. The compound is diamagnetic. The compound [Ru2Cp2(mu3-Se 2)(mu3-Se)]2 (2) is obtained under similar conditions in the presence of air. This structure comprises a centrosymmetric Ru4Se6 dimer formed from the two bridging Se groups and the two bridging Se2 groups. Each Ru center is pi-bonded to a Cp ring. The reaction of solid [RuClCp(PPh3)2] with a Te n2- polytelluride solution in DMF leads to the diamagnetic compound [(RuCp-(PPh3))2(mu2-(1,4-eta:3,6- eta)Te6)] (3). Here the Ru centers are bound to a bridging Te 6 chain at the 1, 4, 3, and 6 positions, leading to a bicyclic Ru2Te6 ring. Each Ru atom is bound to a Cp ring and a PPh3 group. This dimer possesses a center of symmetry. The structure of 3 is the first example of a bicyclic complex where fusion occurs along a Te-Te bond. If the same reaction is carried out in DMF/CH2Cl 2, rather than DMF, then [(RuCp(PPh3))2-(mu2- (1,4-eta:3,6-eta)Te6)]·CH2Cl2 (4) is obtained. In the solid state it possesses the same Ru2Te6 structural unit as does 3, but the unit lacks a crystallographically imposed center of symmetry. The electronic structures of 3 and 4 have been analyzed with the use of first principles density functional theory. Bond order analysis indicates that the Te-Te bond where fusion occurs has a shared bonding charge of about 2/3 of that found for Te-Te single bonds.

The compounds Ru(C?CC?CFc)(PP)Cp [PP=dppe (1), dppm (2)], have been obtained from reactions between RuCl(PP)Cp and FcC?CC?CSiMe3 in the presence of KF (1) or HC?CC?CFc and K[PF6] (2), both with added dbu. The dppe complex reacts with Co2(CO)6 (L2)[L2=(CO)2, dppm] to give 3, 4 in which the Co2(CO)4 (L2) group is attached to the outer C?C triple bond. The PPh 3 analogue of 3 (5) has also been characterised. In contrast, tetracyanoethene reacts to give two isomeric complexes 6 and 7, in which the cyano-olefin has added to either C?C triple bond. The reaction of RuCl(dppe)Cp with HC?CC?CFc, carried out in a thf/NEt3 mixture in the presence of Na[BPh4], gave [Ru{C?CC(NEt3)- CHFc}(dppe)Cp]BPh4 (8), probably formed by addition of the amine to an (unobserved) intermediate butatrienylidene [Ru(-C-C-C-CHFc)(dppe)Cp]+. The reaction of I2 with 8 proceeds via an unusual migration of the alkynyl group to the Cp ring to give [RuI(dppe) {eta-C5H4 C?CC(NEt3)-CHFc}]I3 (9). Single-crystal X-ray structural determinations of 1, 2 and 4-9 are reported. Published by Elsevier B.V.
