Coordination-induced condensation of [Ta6O19]8-: Synthesis and structure of [{(C6H6)Ru}2Ta6O19]4- and [{(C6H6)RuTa6O18}2(mu-O)]10-

Reaction of [(C6H6)RuCl2]2 and Na8[Ta6O19] gives two new hybrid organometallic POM complexes, Na10[{(C6H6)RuTa6O18}2(mu-O)]¡¤39.4H2O (Na10-1) and Na4(trans-[{(C6H6)Ru}2Ta6O19]¡¤20H2O (Na4-2). In both cases the half-sandwich fragments {(C6H6)Ru}2+ are coordinated as additional vertices to the {Ta3(mu2-O)3} triangles of the hexatantalate. According to NMR and ESI-MS data, the dimeric complex [{(C6H6)RuTa6O18}2(mu-O)]10- dissociates in water with the formation of monomeric [(C6H6)RuTa6O19]6- species (1a). X-ray structural characterization and aqueous speciation of the complexes by 13C, 1H, and DOSY NMR; ESI-MS; and capillary electrophoresis (CE) have been carried out.

Studies on an (S)-2-amino-3-(3-hydroxy-5-methyl-4-isoxazolyl)propionic acid (AMPA) receptor antagonist IKM-159: Asymmetric synthesis, neuroactivity, and structural characterization

IKM-159 was developed and identified as a member of a new class of heterotricyclic glutamate analogues that act as AMPA receptor-selective antagonists. However, it was not known which enantiomer of IKM-159 was responsible for its pharmacological activities. Here, we report in vivo and in vitro neuronal activities of both enantiomers of IKM-159 prepared by enantioselective asymmetric synthesis. By employment of (R)-2-amino-2-(4- methoxyphenyl)ethanol as a chiral auxiliary, (2R)-IKM-159 and the (2S)-counterpart were successfully synthesized in 0.70% and 1.5% yields, respectively, over a total of 18 steps. Both behavioral and electrophysiological assays showed that the biological activity observed for the racemic mixture was reproduced only with (2R)-IKM-159, whereas the (2S)-counterpart was inactive in both assays. Racemic IKM-159 was crystallized with the ligand-binding domain of GluA2, and the structure revealed a complex containing (2R)-IKM-159 at the glutamate binding site. (2R)-IKM-159 locks the GluA2 in an open form, consistent with a pharmacological action as competitive antagonist of AMPA receptors.

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.Recommanded Product: (1,3-Bis(2,4,6-trimethylphenyl)-2-imidazolidinylidene)dichloro(phenylmethylene)(tricyclohexylphosphine)ruthenium, you can also check out more blogs about246047-72-3

Rate acceleration in olefin metathesis through a fluorine-ruthenium interaction

The synthesis, structure, and performance of new ruthenium-based olefin metathesis catalysts, featuring fluorinated NHC ligands are presented. The introduction of halogen atoms into the N-heterocyclic carbene ligand profoundly alters the catalytic activity and can afford a more efficient catalyst. Structural investigations suggest that a fluorine-ruthenium interaction is responsible for this increased activity. Copyright

A new polytopic bis-diazacrown-ether-polypyridine ligand and its complexes with Zn(II) salts and mononuclear and dendritic Ru(II) precursors. Synthesis, absorption spectra, redox behavior, and luminescence properties

The new polytopic receptor 1 containing two terpyridine, one phenanthroline, and two diazacrown-ether sites has been prepared using a modular approach. Such a new species contains several pieces of information in its structure which can be processed by different metal ions to give different supramolecular inorganic architectures. Actually, reaction of 1 with Zn(CH3COO)2 in methanol, and subsequent anion exchange, afforded the intramolecular ring-type [Zn(1)]2+ complex, which appears to be formed by a self-assembling reaction. A different synthetic approach, stepwise synthesis, allowed us to synthesize the two multicomponent compounds [(bpy)2Ru(mu-1)Ru(bpy)2]4+ (Ru2; bpy = 2,2?-bipyridine) and [{(bpy)2Ru(mu-2,3-dpp)})2Ru(mu-1)Ru{(mu-2,3-dpp) Ru(bpy)2}2])12+ (Ru6; 2,3-dpp = 2,3-bis(2-pyridyl)pyrazine). The absorption spectra and luminescence properties of 1 and [Zn(1)]2+ are dominated by pi ? pi* transitions and excited states. The absorption spectra of the ruthenium compounds are dominated by ligand-centered (LC) bands in the UV region and metal-to-ligand charge-transfer (MLCT) bands in the visible. The latter compounds undergo several reversible metal-centered oxidations and ligand-centered reductions in the potential window investigated (-2.0/+2.0 V versus SCE) and exhibit MLCT luminescence in both acetonitrile fluid solution at room temperature and in butyronitrile rigid matrix at 77 K. Both the redox and photophysical properties of Ru2 and Ru6 can be assigned to specific subunits of the multicomponent structures. The data indicate that the {Ru(bpy)2})2+ and the dendritic {Ru[(mu-2,3-dpp)Ru(bpy)2]2}6+ fragments appended to the polytopic 1 ligands behave as independent components of the multicomponent arrays.

Regioselectivity of Stoichiometric Metathesis of Vinylsilanes with Second-Generation Grubbs Catalyst: A Combined DFT and Experimental Study

The regioselectivity of metathesis reactions of trisubstituted vinylsilanes H2C=CHSiR3 (SiR3 = SiCl3, SiCl2Me, SiClMe2, SiMe3, Si(OEt)3) with the second-generation ruthenium alkylidene complex has been studied theoretically, by density functional theory (DFT), and experimentally. The DFT results indicate that cycloreversion is the rate-determining step and the formation of a thermodynamically stable ruthenium methylidene complex and PhCH=CHSiR3 is generally preferred. However, the regioselectivity of the process can be also governed by the relative stabilities of the ruthenacyclobutane intermediates, which depend on the electronic and steric properties of the SiR3 substituent. Higher stability of alpha,beta-disubstituted ruthenacyclobutanes in comparison to alpha,alpha-disubstituted ruthenacyclobutanes is predicted, in contrast to the corresponding intermediates formed during metathesis of common alpha-olefins. The stabilizing Ru-Cbeta interaction in the ring is strengthened by the electron-donor SiR3 substituent at Cbeta. The experiments performed have shown selectivity toward styrene formation for SiR3 = SiClMe2, SiMe3, whereas a preference for the formation of ruthenium methylidene and PhCH=CHSiR3 has been observed for SiR3 = SiCl3, SiCl2Me, Si(OEt)3, in accordance with the theoretical predictions.

Alkene isomerization/enamide-ene and diene metathesis for the construction of indoles, quinolines, benzofurans and chromenes with a chiral cyclopropane substituent

A synthetic method for bicyclic heterocycles, such as indole, benzofuran and chromene derivatives bearing a chiral cyclopropane at the 2-position, was established using isomerization of a terminal olefin and enamide-ene or diene metathesis. This route can also be applied to chiral 2-cyclopropylquinoline synthesis (both cis and trans).

Room-temperature photochromism in cis- and trans-[Ru(bpy) 2(dmso)2]2+

We report on phototriggered Ru-S ? Ru-O and thermal Ru-O ? Ru-S intramolecular linkage isomerizations in cis- and trans-[Ru(bpy) 2(dmso)2]2+. The cis complex features only S-bonded sulfoxides (cis-[S,S]), whereas the trans isomer is characterized by S- and O-bonded dmso ligands. Both cis-[S,S] and trans-[S,O] exhibit photochromism at room temperature in dmso solution and ionic liquid (IL). Rates of reaction in IL were monitored by UV-visible spectroscopy and are similar to those reported in dmso solution (kO?S ranges from ?10 -3 to 10-4 s-1). Cyclic voltammetric measurements of cis-[S,S] and trans-[S,O] are consistent with an electrochemically triggered linkage isomerism mechanism. While both cis-[S,S] and trans-[S,O] are photochromic at room temperature, neither complex is emissive. However, upon cooling to 77 K, cis-[S,S] exhibits LMCT (ligand-to-metal charge transfer) emission typical of many ruthenium polypyridine complexes. In contrast to cis-[S,S], trans-[S,O] does not show any detectable emission even at 77 K.
