Solution viscosity effects on the heterogeneous electron transfer kinetics of ferrocenemethanol in dimethyl sulfoxide-water mixtures

The electrochemical kinetics for the oxidation of ferrocenemethanol (FcCH2OH) over the whole composition range of dimethyl sulfoxide (DMSO)-water solutions of different viscosities (I¡¤) containing 50.0 mM (CH3)4NClO4 (TMAP) at a Pt microelectrode was studied using scanning electrochemical microscopy (SECM). The measured diffusion coefficient, DFcCH2OH, as well as the standard rate constant of the heterogeneous electron transfer, k0, as a function of solution composition, showed a minimum at about a DMSO molar fraction (xDMSO) of 0.33, corresponding to the mixture with the maximum solution viscosity. The largest k0 value found, 2.06 A¡À 0.31 cm s-1 in pure water (electrolyte) medium, was about 15 times larger than that obtained in the solution of xDMSO = 0.33 (0.14 A¡À 0.02 cm s-1). A good linear correlation between ln k0 and ln I¡¤ was observed within the solution composition range of 0.10 a?? xDMSO a?? 0.60. An excellent linear correlation between ln k0 and ln I?L, the longitudinal relaxation time, was also obtained with a slope equal to 1.0 when xDMSO = 0-0.60. Unusually small rate constants found in the solutions of xDMSO a?? 0.70 were attributed to adsorption effects at the tip and the substrate electrode. The k0 obtained for the present system was generally found to be inversely proportional to the viscosity of the solution and directly proportional to the diffusion coefficient of the electroactive species.

Synthesis, chemical reactivity and electrochemical behaviour of mono- and difluoro metallocenes

We report the synthesis of mono- and 1,1?-difluoro-substituted metallocenes (ferrocene, ruthenocene) and of asymmetrical 1,1?-disubstituted ferrocenes with one substituent being fluorine. Lithiation of metallocenes and subsequent addition of the fluorinating agent NFSI gave the fluorinated metallocenes after optimization of the experimental conditions. All new compounds were comprehensively characterized and the cyclic voltammograms of fluoro- and 1,1?-difluoroferrocene were recorded and compared to other mono- and dihalogenated ferrocenes. Half-wave potentials of +106 mV and +220 mV vs. FcH0/+ were obtained for monofluorinated species and difluorinated ferrocene, respectively. Both values are remarkably low compared to the other halogenated ferrocenes (Cl, Br, and I). Finally, 1-bromo-1′-fluoro-ferrocene turns out to be an ideal starting material for further fluoro-substituted ferrocene derivatives.

The stability of diazonium ion terminated films on glassy carbon and gold electrodes

Glassy carbon (GC) and Au electrodes were modified with aminophenyl films by electroreduction of the corresponding diazonium salt. Aminophenyl films were diazotised using both aqueous and non-aqueous conditions, to generate film-based phenyldiazonium ions. The stabilities of the diazonium terminated films, to exposure to air and in acidic solution, were investigated by cyclic voltammetry (CV). For films of the same thickness, those grafted to Au substrates are more stable than those grafted to GC.

Metal-catalyzed electrochemical diazidation of alkenes

Vicinal diamines are a common structural motif in bioactive natural products, therapeutic agents, and molecular catalysts, motivating the continuing development of efficient, selective, and sustainable technologies for their preparation. We report an operationally simple and environmentally friendly protocol that converts alkenes and sodium azide?both readily available feedstocks?to 1,2-diazides. Powered by electricity and catalyzed by Earth-abundant manganese, this transformation proceeds under mild conditions and exhibits exceptional substrate generality and functional group compatibility. Using standard protocols, the resultant 1,2-diazides can be smoothly reduced to vicinal diamines in a single step, with high chemoselectivity. Mechanistic studies are consistent with metal-mediated azidyl radical transfer as the predominant pathway, enabling dual carbon-nitrogen bond formation.

Substituent effects in the iron 2p and carbon 1s edge Near-Edge X-ray Absorption Fine Structure (NEXAFS) spectroscopy of ferrocene compounds

The iron 2p and carbon 1s near-edge X-ray absorption fine structure (NEXAFS) spectra of substituted ferrocene compounds (Fe(Cp-(CH3) 5)2, Fe(Cp)(Cp-COOH), Fe(Cp-COOH)2, and Fe(Cp-COCH3)2) are reported and are interpreted with the aid of extended Hiickel molecular orbital (EHMO) theory and density functional theory (DFT). Significant substituent effects are observed in both the Fe 2p and C 1s NEXAFS spectra. These effects can be related to the electron donating/withdrawing properties of the cyclopentadienyl ligands and their substituents as well as the presence of pi* conjugation between the cyclopentadienyl ligand and unsaturated substituents.

Ferrocenyl oligo(phenylene-vinylene) thiols for the construction of self-assembled monolayers

A short and efficient preparation of conjugated oligo(phenylene-ethylene) thiols bearing redox-active ferrocene moieties is described. While minimising the number of synthetic steps, the proposed strategy permits the development of sets of oligomers with varying chain length. The redox properties of the compounds in solution are determined. Preliminary studies of self-assembled monolayers (SAMs) on gold electrodes are discussed, and indicate that electron transfer through the SAMs is indeed rapid. Wiley-VCH Verlag GmbH & Co.

Electrochemical Generation and Detection of Transient Concentration Gradients in Microfluidic Channels. Theoretical and Experimental Investigations

Transient concentration gradients generated and detected electrochemically in continuous flow microchannels were investigated by numerical simulations and amperometric measurements. Operating conditions including device geometry and hydrodynamic regime were theoretically delineated for producing gradients of various profiles with tunable characteristics. Experiments were carried out with microfluidic devices incorporating a dual-channel-electrode configuration. Under these conditions, high electrochemical performance was achieved both to generate concentration gradients and to monitor their dynamics along linear microchannels. Good agreement was observed between simulated and experimental data validating predictions between gradient properties and generation conditions. These results demonstrated the capability of electrochemical microdevices to produce in situ tunable concentration gradients with real-time monitoring. This approach is versatile for the active control in microfluidics of microenvironments or chemical gradients with high spatiotemporal resolution.

Synthesis, characterization and second-order nonlinear optical behaviour of ferrocene-diketopyrrolopyrrole dyads: The effect of alkene: Vs. alkyne linkers

New, thermally stable dipolar ferrocene-diketopyrrolopyrrole (Fc-DPP) dyads with alkene as a linker exhibited structure dependent first hyperpolarizabilities, betaHRS, recorded by a femtosecond HRS technique using a femtosecond (120 fs) pulsed laser light system at 900 nm at ambient temperature. On the basis of linear optical, electrochemical and TD-DFT studies, a good structure-polarization relationship has been established to account for the observed trends in first hyperpolarizabilities. The dyads exhibited fluctuating but matching solvatochromism. Nonlinear optical properties are modulated both by the strength of the acceptor as well as the length and nature of the pi-conjugation bridge. betaHRS of the dyads were compared with structurally related dyads in which the DPP core and the Fc donor are linked via an alkyne bridge. It is interesting to observe that the replacement of an alkyne link with alkene in these D-pi-A chromophores does not necessarily furnish enhanced betaHRS.
