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.

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.

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.

Poly(vinyl ferrocene) redox behavior in ionic liquids

We describe in this report a systematic electrochemical characterization of the ion-solvent coupling mechanisms of poly(vinyl ferrocene) (PVF) in pure ionic liquid (IL) and 0.1 M IL aqueous solutions. Our study showed that the unique solvation and ionic properties of ILs significantly affected the break-in process and the ion-solvent transport mechanisms of PVF redox switching. A square model that emphasized both faradaic and nonfaradaic processes of PVF was used to explain the unique irreversible break-in effect in the pure ILs. The electrochemical quartz crystal microbalance technique was used to characterize the PVF redox processes in 0.1 M 1-butyl-3-methyl imidazolium tetrafluoroborate and 0.1 M methanesulfonate ILs in which an obvious difference of cyclic voltammogram was observed. Our results suggested the existence of strong IL-polymer interaction in 0.1 M methanesulfonate IL solutions, i.e., not only the anions but also the IL molecules interacted with the PVF matrix. The cations were later removed from the PVF matrix to balance the excessive positive charge in PVF oxidation. Our study confirmed that IL was not only an electrolyte but also a solvent in PVF redox switching processes. Various types of interactions between PVF and the IL, including dispersion, dipole induction, dipole orientation, hydrogen-bonding, or ionic/charge-charge interactions, could significantly change the PVF redox dynamics. Thus, IL tremendous diversity in structural and chemical properties and their distinctive properties offer us an excellent opportunity to explore IL-polymer interactions and to dynamically control the conductive polymer relaxation processes and their redox switching mechanism for various applications.
