Metal-polypyridyl complexes with pendant adenine and thymine groups as building blocks for hydrogen-bonded supramolecular assemblies

Reaction of 5-bromomethyl-2,2?-bipyridine with adenine or thymine afforded mixtures of N-alkylated products, from which the ligands bipy-A [in which the adenine is alkylated at the N(9) position] and bipy-T [in which the thymine is alkylated at the N(1) position] could be isolated; these were used to prepare [Ru(bipy)2(bipy-A)[PF6]2 and [Os(bipy)2 (bipy-T)][PF6]2 (of which the former was crystallographically characterized) in which the adenine and thymine fragments are pendant from the {M(bipy)3}2+-type core.

Enantioselective hydrogenation of levulinic acid esters in the presence of the RuII-BINAP-HCl catalytic system

The rate of hydrogenation of gamma-ketoesters MeCOCH2CH 2COOR (R = Et, Pri, But) in the presence of the chiral RuII-BINAP catalyst (BINAP is 2,2?- bis(diphenylphosphino)-1,1?-binaphthyl) greatly increases upon the addition of 5-10 equivalents of HCl with respect to ruthenium. In the hydrogenation of ethyl levulinate, the optically active gamma-hydroxy ester initially formed would cyclize by ?95% to give gamma-valerolactone with optical purity of 98-99% ee. When the Ru(COD)(MA)2-BINAP-HCl catalytic system is used (COD is 1,5-cyclooctadiene, MA is 2-methylallyl), complete conversion of the ketoester (R = Et) in EtOH is attained in 5 h at 60C under an H2 pressure of 60-70 atm.

Discrete covalent organic-inorganic hybrids: Terpyridine functionalized polyoxometalates obtained by a modular strategy and their metal complexation

The rational design and synthesis of organic-inorganic hybrids as functional molecular materials relies on both the careful conception of building-blocks and the strategy for their assembly. Three families of trialkoxo polyoxometalates (Lindqvist 2, Anderson 3, Dawson 4) grafted with remote terpyridine coordination sites have been synthesized to extend the available building-blocks. These new units can be combined with metal complexes that play a role as (i) chromophores toward charge-separated systems in light-harvesting devices and (ii) coordination motifs for metal-directed self-assembly toward multifunctional molecular hybrid materials. The X-ray crystal structures of polyoxometalate-terpyridine hybrids indicate distances of 21 A and 19 A between the two terpyridyl coordination sites in 2 and 3, respectively, with angles between the coordination vectors of 180 and 177.4, respectively. Lindqvist 2 displays a reduction at -0.52 V vs SCE while Anderson 3 exhibits one reversible oxidation attributed to Mn(III)/Mn(IV) (+0.75 V vs SCE) and a broad wave at -1.28 V vs SCE assigned to the Mn(III)/Mn(II) reduction. Dawson 4 displays several processes on a wide range of potentials (+0.5 to -2.0 V vs SCE) centered on V(V), W(VI) and the organic ligand in order of decreasing potentials. The grafted terpyridine ligands in Anderson 3 and Dawson 4 were successfully coordinated to {PdCl}+ and {RuCl 3} moieties, respectively. The polyoxometalates and transition metal complexes retain their intrinsic properties in the final assemblies.

NMO{dot operator}TPB: A Selectivity Variation on the Ley-Griffith TPAP Oxidation

A non-hygroscopic tetraphenylborate salt of N-methylmorpholine-N-oxide (NMO) is reported (NMO{dot operator}TPB), which modulates the standard Ley-Griffith oxidation such that benzylic and allylic alcohols are oxidised selectively. An attractive feature of this new protocol is that anhydrous conditions are not required for this selective tetra-n-propylammonium perruthenate (TPAP) oxidation, superseding the requirement of molecular sieves.

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 114615-82-6 is helpful to your research., Related Products of 114615-82-6

Metal-ion dependent reactivity of 2-(2′-thienyl)pyridine (Hthpy)

The reaction of 2-(2’thienyl)pyridine (Hthpy) with palladium acetate results in a clean conversion to the mu-acetato-bridged dimeric cyclometallated complex <(thpy)Pd(mu-OAc)Pd(thpy)> in which a new Pd-C bond is formed at the 3′ position of the thienyl ring.In contrast, treatment with Na under similar conditions only results in the formation of the complex <(HL)AuCl3> in which the ligand acts as a monodentate N-donor.At higher temperatures the reaction of Na with Hthpy yields a complex mixture of products, including complexes of 2-(5′-chloro-2′-thienyl)pyridine and 5,5′-bis(2-pyridyl)-2,2′-bithienyl.Independent syntheses of these latter compounds have confirmed their identities.The reaction of 2-(2’thienyl)pyridine with (bpy = 2,2′-bypyridine) in the presence of a chloride ion abstractor yields salts of the cation 2+ which contains a bidentate N,S-bonded ligand.

Ionic-tagged catalytic systems applied to the ethenolysis of methyl oleate

A novel high selective ionophilic Hoveyda-type complex for the methyl oleate ethenolysis was prepared from Grubbs first generation catalyst. Ethenolysis under classical biphasic systems in ionic liquids showed to be mass-transference limited. This drawback was successfully solved by the catalyst dispersion on high specific surface area inorganic supports through a thin layer of ionic liquids (ILs). The supported ionic liquid phase (SILP) catalyst properties were patterned by the support type, IL cation and support/IL mass ratio. The SILP prepared with the IL 1-isopentyl-3-methylimidazole hexafluorophosphate and silica showed a turnover number higher (up to 2350) than that of biphasic systems (up to 1045).

gamma-Lactones as templates in ring-closing metathesis: Enantioselective synthesis of medium sized carbocycles fused to butyrolactones

A methodology for accessing enantiomerically enriched carbocyclic systems fused to gamma-lactones is described. Key steps are the stereoselective synthesis of highly substituted gamma-lactones and ring-closing metathesis of the suitable ramifications. The process permits the choice of stereochemistry, regioselectivity and ring size of the fused compounds.

Optimizing the photovoltaic performance of thiocyanate-free ruthenium photosensitizers by structural modification of C^N cyclometalating ligand in dye-sensitized solar cells

Five new thiocyanate-free ruthenium(II) complexes with different electron-donating functionalized cyclometalating ligands C^N were synthesized, characterized and applied as photosensitizers in dye-sensitized solar cells (DSSCs). Their photophysical, electrochemical, thermal and photovoltaic properties have been investigated and density functional theory (DFT) calculations have been carried out on these dyes. These dyes exhibit good thermal stability with the onset decomposition temperature at 5% weight-loss (Td) of around 330 C. The DSSC device using the Ru(II) dye with the 9-tolylcarbazole chromophore exhibited the highest power conversion efficiency (eta) up to 3.39%, with a short-circuit photocurrent density (Jsc) of 8.06 mA cm-2, an open-circuit photovoltage (Voc) of 0.62 V and a high fill factor (ff) of 0.68 under illumination of an AM 1.5 solar cell simulator.
