Synthesis and electrochemical study of Pt-based nanoporous materials

In the present work, a variety of Pt-based bimetallic nanostructured materials including nanoporous Pt, Pt-Ru, Pt-Ir, Pt-Pd and Pt-Pb networks have been directly grown on titanium substrates via a facile hydrothermal method. The as-fabricated electrodes were characterized by scanning electron microscopy, energy dispersive X-ray spectroscopy, X-ray photoelectron spectroscopy, X-ray diffraction and electrochemical methods. The active surface areas of these nanoporous Pt-based alloy catalysts are increased by over 68 (Pt-Pd), 69 (Pt-Ru) and 113 (Pt-Ir) fold compared to a polycrystalline Pt electrode. All these synthesized nanoporous electrodes exhibit superb electrocatalytic performance towards electrochemical oxidation of methanol and formic acid. Among the five nanoporous Pt-based electrodes, the Pt-Ir shows the highest peak current density at +0.50 V, with 68 times of enhancement compared to the polycrystalline Pt for methanol oxidation, and with 86 times of enhancement in formic acid oxidation; whereas the catalytic activity of the nanoporous Pt-Pb electrode outperforms the other materials in formic acid oxidation at the low potential regions, delivering an enhanced current density by 280-fold compared to the polycrystalline Pt at +0.15 V. The new approach described in this study is suitable for synthesizing a wide range of bi-metallic and tri-metallic nanoporous materials, desirable for electrochemical sensor design and potential application in fuel cells.

Design, chemical synthesis, and in vitro biological evaluation of simplified estradiol-adenosine hybrids as inhibitors of 17beta-hydroxysteroid dehydrogenase type 1

A series of estradiol (E2) derivatives were designed to interact with, both the substrate- and the cofactor-binding sites of 17beta-hydroxysteroid dehydrogenase type 1 (17beta-HSD1). These analogues of potent E2-adenosine hybrid inhibitor EM-1745, where the adenosine moiety was replaced by a more stable benzene derivative, were synthesized from estrone using alkene cross-metathesis and Sonogashira coupling reactions as key steps. In vitro biological evaluation of these steroid derivatives revealed that a spacer of 13 methylenes, between the 16beta-position of E2 and the adenosine mimic bearing a carboxylic acid, group, gave the best inhibition of 17beta-HSD1.

Synthesis and molecular structure of [CpRu(PPh3)(Phterpy-N,N?)]Cl complex: Hdentate nature of Phterpy and diterpy

Ligand displacement reactions of the complex [CpRu(PPh3)2Cl] were investigated with N3 terdentate ligands, 4?-phenyl-2,2?: 6,2?-terpyridine (Phterpy) and 1,4-bis(2,2?: 6?,2?-terpyridin-4-yl)benzene (diterpy). The [CpRu(PPh3)2Cl] reacted with these ligands to form stable complexes of the type [CpRu(PPh3)(Phterpy)]X (X = Cl-, PF-6) and [{CpRu(PPh3)}(diterpy){Ru(PPh3)Cp}]X2 (X = CL- PF-6) where the respective ligands coordinate in a bidentate fashion. The X-ray crystal structure of the former complex was determined showing octahedral geometry about the metal center assuming the cyclopentadienyl ligand occupying three coordination sites and Phterpy acts as a bidentate ligand.

An enantioselective synthesis of alpha-alkylated pyrroles: Via cooperative isothiourea/palladium catalysis

Herein we describe the direct enantioselective Lewis base/Pd catalysed alpha-allylation of pyrrole acetic acid esters. This provides high isolated yields of highly enantioenriched products and exhibits broad reaction scope with respect to both reaction partners.

Mixed-Ligand Complexes of Ruthenium(II): Factors Governing Binding to DNA

Binding and spectroscopic parameters for a series of mixed-ligand complexes on binding to DNA have been determined.The application of mixed-ligand complexes permits the variation in geometry, size, hydrophobicity, and hydrogen-bonding ability by systematic variation of complex ligands and the determination of how these factors contribute to DNA binding affinity.Ligands employed include 2,2′-bipyridine (bpy), 1,10-phenanthroline (phen), 4,7-diphenylphenanthroline (DIP), 5-nitrophenanthroline (5-NO2-phen), 4,5-diazafluorene-9-one (flone), and 9,10-phenanthrenequinonediimine (phi).Measurements include equilibrium binding isotherms and enantioselectivities associated with binding, the degree of absorption hypochromism and red shift in the ruthenium charge-transfer band, increases in emission intensities and excited-state lifetimes, perturbations in excited-state resonance Raman spectra (which reflect changes in excited-state charge-transfer distributions as a result of binding to DNA), and determinations of helical unwinding.The complexes examined, with the exception of Ru(bpy)32+, all appear to intercalate and surface-bind to DNA, and for those that bind appreciably, enantioselectivity is observed.Based upon the measurements of spectroscopic properties and binding isotherms, the intercalating ability appears to increase over the series bpy<Quality Control of: Cis-Dichlorobis(2,2′-bipyridine)ruthenium(II).

Ruthenium mediated C-H activation of 2-(arylazo)phenols: Characterization of an intermediate and the final organoruthenium complex

Reaction of 2-(arylazo)phenols with [Ru(PPh3) 2(CO)2Cl2] affords a family of organometallic complexes of ruthenium-(II) of type [Ru(PPh3)2(CO)(CNO-R)] , where the 2-(arylazo)phenolate ligand (CNO-R; R = OCH3, CH 3, H, Gl, and NO2) is coordinated to the metal center as tridentate C,N,O-donor. Another group of intermediate complexes of type [Ru(PPh3)2(CO)(NO-R)(H)] has also been isolated, where the 2-(arylazo)phenolate ligand (NO-R) is coordinated to the metal center as bidentate N,O-donor. Structures of the [Ru(PPh3)2(CO)(NO- OCH3)(H)] and [Ru(PPh3)2(CO)-(CNO-OCH 3)] complexes have been determined by X-ray crystallography. All the complexes are diamagnetic and show characteristic 1H NMR signals and intense MLCT transitions in the visible region. Both the [Ru(PPh 3)2(CO)-(NO-R)(H)] and [Ru(PPh3) 2(CO)(CNO-R)] complexes show two oxidative responses on the positive side of SCE.

Synthesis and conformational analysis of cyclic analogues of inverse gamma-turns

gamma-Turn analogues comprising a modified dipeptide constrained in an eleven-membered ring were prepared by alkene metathesis and analysed by NMR and molecular modelling studies. The results reveal that some of the cyclic analogues form inverse gamma-turns and preferentially adopt conformations determined by the identity of the incorporated amino acid residues and the nature of the constraining linker (E/Z-alkene or alkane).

Synthesis and characterization of sterically enlarged hoveyda-type olefin metathesis catalysts

A series of four ruthenium-based olefin metathesis catalysts has been prepared. These new complexes were designed with nanofiltration in organic media in mind; steric enlargement and functionalisation by means of polar ethylene glycol chains were incorporated. New complexes based on the stable 2nd generation Hoveyda-type architecture and featuring substitution either on the NHC backbone or on the N-aryl substituent of the NHC have been prepared and fully characterized. The application of these complexes in a series of olefin metathesis transformations revealed that these modified catalysts retained activity on par with the parent Hoveyda catalyst thus validating the disclosed ligand design.
