Relative stability of half-sandwich eta6-benzene Ru(II) complexes of tridentate (2-pyridyl)alkylamine ligands of varying chelate ring-size: Nucleophilic addition of hydride ion onto the benzene ring

A full account of half-sandwich complexes of ruthenium(II) having three-legged “piano-stool” geometry supported by tridentate (2-pyridyl)alkylamine ligands is presented. Reaction of the dimer [{(eta6-C6H6)RuCl(mu-Cl)}2] with N-methyl-N,N-bis(2-pyridylmethyl)amine (MeL*) in CH3OH in the presence of NH4PF6 affords the complex [(eta6-C6H6)Ru(MeL*)][PF6]2 (1). A similar reaction with N-methyl-N,N-bis(2-pyridylethyl)amine (MeL**), however, affords a non-organometallic Ru(III)-dimeric complex [(MeL* *)2 Ru2III (mu -O) (mu -Cl) Cl2] [PF6] (5) (the composition of this complex has been established by physicochemical method). Nucleophilic addition reaction on 1 with NaBH4 leads to the isolation of a cyclohexadienyl complex [(eta5-C6H7)Ru(MeL*)][PF6] (3). The molecular structure of 1 ¡¤ 2CH3CN, 3, and previously reported cyclohexadienyl complex [(eta5-C6H7)Ru(MeL)][PF6] (4) [MeL = N-methyl-[(2-pyridyl)ethyl(2-pyridyl)-methyl]amine], obtained from the reaction between NaBH4 and previously reported “piano-stool” complex [(eta6-C6H6)Ru(MeL)][PF6]2 (2), has been confirmed by X-ray crystallography. Solution-state structure of new complexes 1 and 3 has been elucidated by their 1H NMR spectra in CD3CN. The behavior of complex 3 has been investigated with the aid of two-dimensional 1H NMR spectroscopy, as well. An attempt has been made to provide a rationale for the effect of supporting tridentate N-donor ligand [MeL, MeL*, and MeL**], varying in the chelate ring-size on (i) the relative stability of half-sandwich eta6-benzene Ru(II) complexes and (ii) the electrophilicity of Ru(II)-coordinated benzene ring on the nucleophilic addition reactions.

Syntheses and quadratic hyperpolarizabilities of some (pyridylalkynyl)metal complexes: Crystal structures of [Ni{2-(C?C)C5H3NNO2-5}(PPh 3)(eta-C5H5)], [Au{2-(C?C)C5H3NNO2-5}(PPh3)] and [Au{2-(C?C)C5H4N}(PPh3)]

The complexes [Ru{2-(C?C)C5H3NR-5}(PPh3) 2(eta-C5H5)] (R = NO2 1 or H 2), [Ni{2-(C?C)C5H3NR-5}(PPh3)-(eta-C 5H5)] (R = NO23 or H 4) and [Au{2-(C?C)C5H3NR-5}L] (L = PPh3, R = NO2 5 or H 6; L = PMe3, R = NO2 7) have been synthesized and 3, 5 and 6 structurally characterized; no significant increase in quinoidal vinylidene contribution to the acetylide ground-state structure is apparent on progression from structurally characterized phenylacetylide complexes to the new pyridylacetylide complexes, or upon replacement of 5-H by 5-NO2 in progressing from 6 to 5. The molecular quadratic optical non-linearities of 1-7 have been determined by hyper-Rayleigh scattering (HRS). The HRS measurements at 1064 nm are consistent with an increase in beta upon replacement of phenyl by an N-heterocyclic ring (replacing a nitrophenylacetylide by a nitropyridylacetylide ligand) for the ruthenium and gold systems, but with no change for the nickel complexes, and with an increase in non-linearity upon replacement of PMe3 by PPh3 in progressing from 7 to 5. The bulk second-order susceptibilities of the series have been determined by Kurtz powder measurements at 1054 nm, with the only significant response (about eight times that of urea) being that of 3; this complex was the only one of the three structurally characterized to pack non-centrosymmetrically in the crystal lattice. Electrochemical data for 1-4 have been obtained; comparison to analogous nitrophenylacetlylide complexes reveals that replacing nitrophenylacetylide by nitropyridylacetylide leads to a significant increase in MII/III oxidation potential for the ruthenium complexes, but to no change for the nickel examples. The parameter EoMII/II -EoNO2/NO2 – was evaluated for 1-4, results for M = Ru vs. Ni being consistent with experimentally determined non-linearities, i.e. smaller DeltaEo and larger non-linearities for ruthenium vs. nickel.

Photoinduced electron transfer kinetics of linked Ru-Co photocatalyst dyads

Two new supramolecular photocatalyst dyads based on the [Ru(2,2?-bipyridine)3]2+ photosensitizer linked to a macrocyclic Co(II)tetra(pyridyl) catalyst for proton reduction are reported. The dyads differ primarily in the bridging ligand which links the molecular modules; the first being a short and flexible linker, and the second a longer and electronically conjugated linker. Ultrafast transient optical spectroscopy was used to monitor the photoinduced kinetics of the dyads following visible excitation of the photosensitizer module. Direct comparison of transient spectra and kinetics indicates that there are indeed substantial differences between the ultrafast transient optical spectroscopy of the dyads, but there is no indication of oxidative quenching of the photosensitizer module by the catalyst module. These initial design and characterization studies of the linked Ru(II)?Co(II) dyads provide an important foundation for advanced designs of systems for efficient solar energy conversion by molecular architectures.

The preparation of rutile type solid solutions in (TiO2)x-(RuO2)1-x system in the 0?x?0.7 concentration range is described. The single phase solid solutions are formed by controlled nanocrystallization of amorphous gels prepared by the sol-gel method. The kinetics of this crystallization process has been analyzed. It was found that the crystallization does not correspond to the Johnson-Mehl-Avrami model and it can be described by the two-parameter Sestak-Berggren kinetic model.

Discovery and investigation of anticancer ruthenium-arene Schiff-base complexes via water-promoted combinatorial three-component assembly

The structural diversity of metal scaffolds makes them a viable alternative to traditional organic scaffolds for drug design. Combinatorial chemistry and multicomponent reactions, coupled with high-throughput screening, are useful techniques in drug discovery, but they are rarely used in metal-based drug design. We report the optimization and validation of a new combinatorial, metal-based, three-component assembly reaction for the synthesis of a library of 442 Ru-arene Schiff-base (RAS) complexes. These RAS complexes were synthesized in a one-pot, on-a-plate format using commercially available starting materials under aqueous conditions. The library was screened for their anticancer activity, and several cytotoxic lead compounds were identified. In particular, [(eta6-1,3,5-triisopropylbenzene)RuCl(4-methoxy-N-(2- quinolinylmethylene)aniline)]Cl (4) displayed low micromolar IC50 values in ovarian cancers (A2780, A2780cisR), breast cancer (MCF7), and colorectal cancer (HCT116, SW480). The absence of p53 activation or changes in IC50 value between p53+/+ and p53-/- cells suggests that 4 and possibly the other lead compounds may act independently of the p53 tumor suppressor gene frequently mutated in cancer.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Computed Properties of C12H12Cl4Ru2, you can also check out more blogs about37366-09-9

New approaches to olefin cross-metathesis

New methodology for the selective cross-metathesis (CM) of terminal olefins employing ruthenium benzylidene 1 is described. CM with symmetric internal olefins was found to provide a useful means for homologating terminal olefins to protected allylic alcohols, amines, and esters. Due to the limited commercial availability of symmetric internal olefins, a two-step CM procedure was developed in which terminal olefins were first homodimerized prior to the CM reaction. Terminal olefins with allylic methyl substituents were observed to provide CM products in diminished yield albeit with markedly improved trans-selectivity. Reaction rates were measured for CM reactions utilizing butenediol and allyl alcohol derivatives, and the results demonstrated distinct advantages in reaction rate and stereoselectivity for reactions employing the disubstituted olefins. In the course of studies of substrates with allylic oxygen substituents, a new CM application was discovered involving the metathesis of acrolein acetal derivatives with terminal olefins. Acrolein acetals, including asymmetric variants derived from tartaric acid, proved to be exceptionally robust and trans-selective CM substrates. In related work, a pinacol-derived vinyl boronate was also found to be a reactive CM partner, providing a novel means for converting terminal olefins into precursors for the Suzuki coupling reaction.

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 172222-30-9 is helpful to your research., Reference of 172222-30-9

A unique ruthenium carbyne complex: A highly thermo-endurable catalyst for olefin metathesis

A cationic ruthenium carbyne complex was prepared and was found to initiate olefin metathesis reactions with good activities, which throws a new light on the design of a new type of ruthenium catalyst for RCM reactions. More importantly, no double bond isomerized by-product was observed even at elevated temperatures in reactions catalyzed by the new carbyne complex. A mechanism involving the in situ conversion of the ruthenium carbyne to a ruthenium carbene complex via addition of an iodide to the carbyne carbon was also proposed.
