Electrochemical behaviour of ferrocenes in tributylmethylphosphonium methyl sulfate mixtures with water and 1,2-dichloroethane

Electron transfer (ET) reactions in ionic liquid (IL)|organic solvent (1,2-dichloroethane, DCE) and IL|water mixtures were investigated using a Pt disk ultramicroelectrode (UME) along with ferrocene (Fc) and ferrocenemethanol (FcCH2OH) redox probes as electroactive species dissolved in the respective mixtures. The IL utilized was tributylmethylphosphonium methyl sulfate (P4441CH3SO4). The diffusion coefficient of each redox species was determined at each incremental increase of DCE or water to the IL using a chronoamperometric technique that is concentration independent. The IL|DCE mixture exhibited little change in the Fc diffusion coefficient, DFc, up to a DCE mole fraction (chiDCE) of 0.5; the observed value, 2.0 ¡Á 10-8 cm2 s-1, agrees well with that typically reported for ILs in the literature. After which, the DFc quickly rose to a value commonly found in conventional molecular solvents, 1.3 ¡Á 10-5 cm2 s-1 (at chiDCE = 0.8). An analogous result was not observed for IL|water mixtures using FcCH2OH, such that DFcCH2OH varied from 0.2 to 1.2 ¡Á 10-9 cm2¡¤s-1 at a chiH2O of 0 to 0.8. It was proposed that a large increase in the DFc in the IL|DCE mixture versus DFcCH2OH in the IL|water series was owing to P4441CH3SO4’s more hydrophobic character. Its hydrophobicity was quantified by measuring the formal ion transfer potentials of the IL component ions at a water|DCE immiscible interface.

Synthesis of alpha-arylalkylferrocenes through cesium fluoride-promoted coupling of arylboronic acids with N-tosylhydrazones

A cesium fluoride-promoted reductive coupling reaction of acylferrocene tosylhydrazones with arylboronic acids has been developed, producing highly substituted alpha-arylalkylferrocenes in moderate to excellent yields. The reaction employs anionic fluorine to facilitate the cleavage of C?B bond. The developed methodology demonstrates a wide substrate scope and high functional groups tolerance. Moreover, the alpha-arylalkylferrocenes compounds were also obtained on a multi-gram scale.

Stabilisation of unusual simultaneous binding of four cytosine nucleobases to copper(II) by a novel network of bifurcated hydrogen bonding

The crystal structure of tetrakis(cytosine)copper(II) perchlorate dihydrate has been determined. All the hydrogen atoms were obtained from Fourier-difference synthesis. The geometry around copper is a bicapped octahedron (4 + 2 + 2*). The adjacent cytosine rings are oriented head-to-tail with respect to each other and are roughly at right angles to the co-ordination plane. The exocyclic oxo groups form an interligand, intracomplex hydrogen-bonding network above and below the co-ordination plane with the exocyclic amino groups of alternate cytosine bases. The EPR and electronic spectra are consistent with the retention of the solid-state structure in solution. The steric effect of the C(2)=O group of cytosine is offset by the presence of the intracomplex hydrogen-bonding network. The trend in E1/2 values of CuII-CuI couples for 1:4 complexes of cytosine, cytodine, pyridine, 2-methylpyridine and N-methylimidazole suggests that both steric effects and pi-delocalizatiori in imidazole and pyridine ligands and the steric effect of C(2)=O in pyrimidine ligands are important in stabilising CuI relative to CuII.

Miniature Gigahertz Acoustic Resonator and On-Chip Electrochemical Sensor: An Emerging Combination for Electroanalytical Microsystems

Performance of electroanalytical lab-on-a-chip devices is often limited by the mass transfer of electroactive species toward the electrode surface, due to the difficulty in applying external convection. This article describes the powerful signal enhancement attained with a 2.54 GHz miniature acoustic resonator integrated with an electrochemical device in a miniaturized cell. Acoustic resonator and an on-chip gold thin-film three-electrode electrochemical cell were arranged facing each other inside a structured poly(methyl methacrylate) chamber. Cyclic voltammetric and chronoamperometric responses of 1 mM ferrocene-methanol were recorded under resonator’s actuation at powers ranging from 0 to 1 W. Finite element analysis was carried out to study the sono-electroanalytical process. Acoustic resonator’s actuation greatly enhances the mass transport of electroactive species toward the electrode surface. The diffusion limited cyclic voltammetric and chronoamperometric currents increase around 10 and 20 times, respectively, with an input power of 1 W compared to those recorded under stagnant conditions. The improvement in electroanalytical process is mainly associated with acoustic resonator’s vibration induced fluid streaming. The advantages of a miniaturized acoustic resonator, including the submillimeter small size, amenability for mass fabrication, cost effectiveness, low energy consumption, as well as outstanding enhancement of coupled electrochemical processes, will enable the production of highly sensitive compact electroanalytical devices.

Recent Advances in Applications of Voltammetric Sensors Modified with Ferrocene and Its Derivatives

This study is on current developments concerning ferrocene (FC) and its derivatives on the basis of electrochemical biosensors and sensors. The distinct physiochemical characteristics of FC have enabled the development of new sensor devices, specifically electrochemical sensors. Several articles have focused on the implementation of FC as an electrode constituent while discussing its electrochemical behavior. Furthermore, typical FC-design-based biosensors and sensors are considered as well as practical examples. The favorable design of FC-based biosensors and general sensors needs adequate control of their chemical and physical characteristics in addition to their surface immobilization and functionalization.

“Polysiloxane-Pd” nanocomposites as recyclable chemoselective hydrogenation catalysts

Polysiloxane-encapsulated “Pd”-nanoclusters were generated by reduction of Pd(OAc)2 with polymethylhydrosiloxane, which functions as a reducing agent as well as a capping material for production and stabilization of catalytically active “Pd”-nanoparticles. Chemoselective hydrogenation of functional conjugated alkenes was achieved by in-situ- or ex-situ-generated polysiloxane-stabilized “Pd”- nanoclusters under mild reaction conditions in high yields. Electron microscopy, UV-vis, and NMR studies of the reaction mixture during the catalytic transformation were performed and, in conjunction with catalyst poisoning experiments, demonstrated unequivocally the role of polysiloxane-encapsulated “Pd”-nanoclusters as the real catalytic species. The recyclability of the “Pd”-nanoclusters was established by reusing the solid left after the reaction.

Mediated Fuel Cells: Soluble Redox Mediators and Their Applications to Electrochemical Reduction of O2 and Oxidation of H2, Alcohols, Biomass, and Complex Fuels

Mediated fuel cells are electrochemical devices that produce power in a manner similar to that of conventional proton exchange membrane fuel cells (PEMFCs). They differ from PEMFCs in their use of redox mediators dissolved in liquid electrolyte to conduct oxidation of the fuel or reduction of the oxidant, typically O2, in bulk solution. The mediators transport electrons (and often protons) between the electrode and the catalysts or chemical reagents in solution. This strategy can help overcome many of the challenges associated with conventional fuel cells, including managing complex multiphase reactions (as in O2 reduction) or the use of challenging or heterogeneous fuels, such as hydrocarbons, polyols, and biomass. Mediators are also commonly used in enzymatic fuel cells, where direct electron transfer from the electrode to the enzymatic active site can be slow. This review provides a comprehensive survey of historical and recent mediated fuel cell efforts, including applications using chemical and enzymatic catalysts.
