Synthesis and Reactivity of Ferrocenyl-Substituted Allylamine Derivatives

[(2-Ferrocenylvinyl)methyl]dimethylamine (2) was obtained in good yields and with perfect regio- and stereoselectivity by reaction of dimethylmethylideneammonium salts with vinylferrocene. After methylation of amine 2, [(2-ferrocenylvinyl)methyl]trimethylammonium iodide (4) was obtained in high yields and used to transfer the ferrocene-containing allyl group to various amines. By controlling reaction conditions, various linear and branched ferrocenyl-substituted allylamines could be obtained with good yields and selectivities. When anilines were used as substrates against ammonium salt 4, compounds originating from Friedel?Crafts reactions were also obtained, with complete regioselectivity towards the para position.

Synthesis and electrochemical properties of slipped-cofacial porphyrin dimers of ferrocene-functionalized Zn-imidazolyl-porphyrins as potential terminal electron donors in photosynthetic models

A systematic series of ferrocene-functionalized Zn-imidazolyl-porphyrins were synthesized to assemble into the slipped-cofacial porphyrin dimers through imidazolyl-to-zinc complementary coordination as artificial photosynthetic models. Direct substitution at the meso position of the porphyrin ring with ferrocence and octamethylferrocene leads to the characteristic electronic structures, while the ferrocene substituents through phenylene-ethenylene and phenylene-ethylene spacers mitigate the electronic communications. Bathochromic shift of Q band, fluorescence quenching, and redox potentials of porphyrin ring are rationalized by the degree of electron-donating ability of the terminal ferrocenes. the Royal Society of Chemistry and the Centre National de la Recherche Scientifique 2006.

Conductivity and electrochemistry of ferrocenyl-imidazolium redox ionic liquids with different alkyl chain lengths

Electroactive ionic liquids obtained by modifying imidazolium with ferrocenyl moiety and alkyl chains of different lengths (n = 1, 4, 8 and 12) were studied in their pure form and dissolved in ethylene/diethylene carbonates (EC/DEC) solvent. Bis(trifluoromethanesulfonyl) imide (TFSI) was used as the anion. The conductivity of the pure ionic liquids (0.1 to 0.04 mS cm?1) was found to decrease with the increase in alkyl chain length as expected from larger van der Waals interactions. The conductivities of carbonate solutions of redox ionic liquid (50% vol.) were less affected by the chain length but were strongly dependent on the presence of Li ions due to their coordination with TFSI, providing viscous solutions (86-111 cP) which decreased the self-diffusion of the redox imidazolium by a factor of 6. The equilibrium potential of the RIL dissolved in the carbonate solvent was not affected by the alkyl chain length, but mass transport by migration caused a distortion in cyclic voltammograms for highly concentrated solutions.

Backbone modification promotes peroxidase activity of G-quadruplex-based DNAzyme

In this work we studied how backbone chemical modifications, such as 2?-O-methyl, phosphorothioate, l-form nucleotides and locked nucleic acid, on G-quadruplex based DNAzymes would affect their peroxidase activity. Our results indicate that 2?-O-methyl modification facilitates the formation of a perfectly compacted parallel structure and significantly promotes peroxidase activity of G-quadruplex based DNAzymes.

Metastable beta Ti-Nb-Mo alloys with improved corrosion resistance in saline solution

The present study explores the microstructural characteristics and electrochemical responses of four metastable beta Ti-Nb-Mo alloys for biomedical implantation. They were synthesized by the cold crucible levitation melting technique, and compositions were selected to keep the molybdenum equivalency close to 12 wt% Moeq. For the sake of comparison, Ti12Mo was also investigated. Microstructural characterization reveals that all the alloys are beta (body-centred cubic structure), and the surface is composed by beta equiaxial grains with dimensions in the range of tens to hundreds mum. The corrosion resistance (potentiodynamic polarization and electrochemical impedance spectroscopy) of the alloys was determined in 0.9 wt% NaCl saline solution at 25 C. The materials spontaneously form a passivating oxide film on their surface, and they are stable for polarizations up to +1.0 VSCE. No evidence of localized breakdown of the oxide layers is found for polarizations more positive than those encountered in the human body. The passive layers show dielectric characteristics, and the wide frequency ranges displaying capacitive characteristics occur for both higher niobium contents in the alloy and longer exposures to the saline solution. The insulating characteristics of the oxide-covered surfaces were investigated by scanning electrochemical microscopy operated in the feedback mode, using ferrocene-methanol as redox mediator. Both z-approach curves and amperometric images were taken over the surface of the samples both at their open circuit potential and polarized. It has been found that Ti8Nb10Mo and Ti16Nb8Mo exhibit the lowest activity towards electron transfer. The new Ti-Nb-Mo ternary alloys are regarded to be potential candidates for biomedical application on the basis of both their microstructural characteristics and their corrosion resistance in saline solution with chloride content equivalent to body fluids.

Impact of metal ions in porphyrin-based applied materials for visible-light photocatalysis: Key information from ultrafast electronic spectroscopy

ProtoporphyrinIX-zinc oxide (PP-ZnO) nanohybrids have been synthesized for applications in photocatalytic devices. High-resolution transmission electron microscopy (HRTEM), X-ray diffraction (XRD), and steady-state infrared, absorption, and emission spectroscopies have been used to analyze the structural details and optical properties of these nanohybrids. Time-resolved fluorescence and transient absorption techniques have been applied to study the ultrafast dynamic events that are key to photocatalytic activities. The photocatalytic efficiency under visible-light irradiation in the presence of naturally abundant iron(III) and copper(II) ions has been found to be significantly retarded in the former case, but enhanced in the latter case. More importantly, femtosecond (fs) transient absorption data have clearly demonstrated that the residence of photoexcited electrons from the sensitizer PP in the centrally located iron moiety hinders ground-state bleach recovery of the sensitizer, affecting the overall photocatalytic rate of the nanohybrid. The presence of copper(II) ions, on the other hand, offers additional stability against photobleaching and eventually enhances the efficiency of photocatalysis. In addition, we have also explored the role of UV light in the efficiency of photocatalysis and have rationalized our observations from femtosecond- to picosecond-resolved studies.

A tunable route for the synthesis of azomethine imines and beta-aminocarbonyl compounds from alkenes

Cyclic azomethine imines possessing a beta-aminocarbonyl motif are accessed from simple alkene and hydrazone starting materials. A thermal, concerted alkene aminocarbonylation pathway involving an imino-isocyanate intermediate is proposed and supported by DFT calculations. A notable feature of the process is the steric shielding present in the dipoles formed, which allows for facile purification of the products by chromatography or crystallization. In addition, a fluorenone-derived reagent is reported, which provides reactivity with several alkene classes and allows for mild derivatization of the dipoles into beta-aminoamides, beta-aminoesters, and beta-amino acids.
