A simple approach for fabrication of microring electrodes

Herein we describe a simple approach for fabrication of microring electrodes by electroless plating a thin layer of gold on polycarbonate (PC) rods. First, the PC rod was exposed to UV light to generate carboxyl groups on the surface. After amination of the surface carboxyl groups by ethylenediamine, the rod was sequentially immersed in HAuCl4 and NaBH4 solutions to form a layer of gold nanoparticles. These gold nanoparticles then functioned as the catalytically active centers for electroless plating thin gold film on the PC rod surface. Finally, the rod surface was thoroughly covered by an insulating glue and fresh microring surface could be obtained easily by laterally cutting with a knife. The electrochemical behavior of thus prepared microring electrodes were characterized by cyclic voltammetry in hydroxymethylferrocene and H2SO4. The whole fabrication process is simple and economic, which can be carried out in ordinary laboratories. In addition, the results of electrocatalytic oxygen reduction demonstrated that the proposed microelectrode could be used as an alternative electrode materials for electrocatalysis and electroanalysis.

An Enantioselective Oxidative C-H/C-H Cross-Coupling Reaction: Highly Efficient Method to Prepare Planar Chiral Ferrocenes

A Pd-catalyzed, asymmetric oxidative cross-coupling reaction between ferrocenes and heteroarenes is described. The process, which takes place via a twofold C-H bond activation pathway, proceeds with modest to high efficiencies (36-86%) and high levels of regio- and enantioselectivity (95-99% ee). In the reaction, air oxygen serves as a green oxidant and excess amounts of the coupling partners are not required. The process is the first example of a catalytic asymmetric biaryl coupling reaction that occurs via double C-H bond activation. Finally, the generated coupling products can be readily transformed into chiral ligands and catalysts.

Lanthanide Ion Chelates of Dibenzyl 1,1′-Diacetylferrocenebis(hydrazonatocarbodithioate)

A new ligand, dibenzyl 1,1′-diacetylferrocenebis(hydrazonatocarbodithioate), Fe[C5H4C(CH3)=NNHCSSCH2C6H5)2] (H2Dafhb) and its chelates with lanthanide ions, Ln(Dafhb)Cl (Ln = lanthanide) have been prepared by the reaction of the H2Dafhb with LnCl3. All compounds were characterized by elemental analyses, IR, (1H) NMR, UV, electrolytic conductivity and TGA measurements. It is shown that the ligand coordinates to the metal in the thiol form and that one chloride ion participates in coordination. The chelates are non-electrolytes in DMF and are more thermostable than the ligand due to formation of chelate rings.

Ion exchange of ferro(ferri)cyanide in polyvinylferrocene films

Ion exchange of ferro/ferricyanide into oxidized polyvinylferrocene (PV-Fc) films occurs upon repetitious cycling of a PV-Fc film between its oxidized and reduced forms in the presence of either Fe(CN)63- and Fe(CN)64-. The ion exchange is evident from cyclic voltammetry and the response of a quartz crystal microbalance coated with a PV-Fc film. Insertion of the multiply charged anions appears to result in deactivation of polyvinylferrocene sites, with the exchanged films initially exhibiting voltammetric waves due to confined ferro(ferri)cyanide. Prolonged cycling of the exchanged films causes complete passivation of the films towards redox species in the film, as well as solution species, suggesting extensive electrostatic cross-linking by the multiply charged anions. Coulometric experiments suggest that approximately one ferro(ferri)cyanide exchanges for three PV-Fc redox sites. The visible spectra of the exchanged films after prolonged cycling suggests the presence of prussian blue-like species in the polymer film which presumably arise from decomposition of the polymer.

Ferrocenyl-naphthalimide donor-acceptor dyads with aromatic spacer groups

The preparation and characterization of a series of dyads containing ferrocene donor and naphthalimide acceptor units, separated by aromatic spacer groups, are reported. The compounds contain a ferrocene-ethenyl spacer component linked to the 4-position of a naphthalimide by an ethynyl bridge, Fc-CH=CH-spacer-C?C-naphthalimide (Fc = ferrocenyl), where the spacers are 1,4-phenyl, 4,4?-biphenyl, and 9,10-anthryl. Precursors to the dyad systems, halo-spacer-C?C-naphthalimide, are also characterized where the halo-spacers are 1-bromophenyl, 4-bromobiphenyl, and 9-iodoanthryl. Various synthetic strategies are examined, with attachment of the spacer to 4-ethynylnaphthalimide followed by reaction with ethenylferrocene proving the most effective route. Crystal structures of the donor-spacer-acceptor (D-S-A) compound (E)-1-ethenylferrocenyl-4-(4-ethynyl-N-methyl-1,8-naphthalimide)benzene (7) and the precursor compounds (E)-4-bromo-4?-(ethenylferrocenyl) biphenyl (2) and 4-ethynyl-4?-(4-ethynyl-N-methyl-1,8-naphthalimide) biphenyl (4) are reported, with packing in the two naphthalimide derivatives dominated by offset pi-stacking interactions. Compounds containing the ferrocenyl groups show the anticipated one-electron oxidation processes at potentials that vary little with the spacer groups. Both the ferrocenyl derivatives and their naphthalimide precursors show reversible reduction waves. The single wave for the phenyl and biphenyl compounds and their precursors is assigned to reversible one-electron reduction of the naphthalimide unit. The corresponding anthracene derivatives display two reversible reductions associated with the naphthalimide and the anthryl moieties, respectively.

Conditional Copper-Catalyzed Azide?Alkyne Cycloaddition by Catalyst Encapsulation

Supramolecular encapsulation is known to alter chemical properties of guest molecules. We have applied this strategy of molecular encapsulation to temporally control the catalytic activity of a stable copper(I)?carbene catalyst. Encapsulation of the copper(I)?carbene catalyst by the supramolecular host cucurbit[7]uril (CB[7]) resulted in the complete inactivation of a copper-catalyzed alkyne?azide cycloaddition (CuAAC) reaction. The addition of a chemical signal achieved the near instantaneous activation of the catalyst, by releasing the catalyst from the inhibited CB[7] catalyst complex. To broaden the scope of our on-demand CuAAC reaction, we demonstrated the protein labeling of vinculin with the copper(I)?carbene catalyst, to inhibit its activity by encapsulation with CB[7] and to initiate labeling at any moment by adding a specific signal molecule. Ultimately, this strategy allows for temporal control over copper-catalyzed click chemistry, on small molecules as well as protein targets.

Electron-Transfer Studies of Model Redox-Active Species (Cationic, Anionic, and Neutral) in Deep Eutectic Solvents

The redox potentials of electroactive species are significantly influenced by the solvation characteristics of the medium. This is manifested in the shift of half-peak potentials with the change in the solvent medium. There have been many approaches till date, both experimental and theoretical to understand the role of molecular solvents in the peak potentials of redox species. The electrochemical studies reported here are aimed at understanding the effect of deep eutectic solvents (DESs) which is distinct from conventional solvents in terms of highly concentrated ionic composition, on the half-peak potentials of some standard redox reactions. The redox species selected for this study are distinct either in terms of their charge [Fe(CN)64-/3-, Ru(NH3)62+/3+, and ferrocene methanol, FcMeOH0/+] or their hydrophilic/hydrophobic properties [methyl viologen and ferrocene]. The redox potentials are compared with the values obtained in the aqueous medium which is very well characterized in terms of solvent reorganization energy and free-energy changes. The cyclic voltammetric behavior of the redox species in DES is significantly different from that of aqueous medium. The diffusion coefficients of the redox species in DES measured by EIS and cyclic voltammetry showed significant deviations from that predicted by Stokes-Einstein equation, indicating the dominant effect of Coulombic interactions within the components of DES.
