Electrolyte effects on enzyme electrochemistry

The electrolytes used in enzymatic biosensors or biofuel cells have always been considered to be inert. However, recent studies have demonstrated that this assumption is not correct and that the nature of the electrolyte needs to be considered. Ion-specific interactions can occur with the faradaic response observed in both direct and mediated electron transfer being modulated by the nature of the salt used in solution. Specific ion effects arise from the Hofmeister series, which is well established in studies of protein systems but not in electrochemical studies of redox enzymes. Recent experimental and theoretical work on explaining the Hofmeister effect is described.

Synthetic, structural and electrochemical studies on some ferrocenylazines: Crystal structures of [4](1)(1,4-dimethyl-2,3-diazabuta-1,3-dien) ferrocenophane and [42](1,1?)bist(1,4-dimethyl-2,3-diazabuta-1,3-dien) ferrocenophane

By reaction of the hydrazones of mono-and 1,1?-diacetylferrocene with mono-and diketones a series of ferrocenylazines has been prepared. The crystal structures of the monobridged ferrocenophane [4](1)(1,4-dimethyl-2,3-diazabuta-1,3-dien) ferrocenophane (II) and of the dibridged ferrocenophane [42](1,1?)bis-(1,4-dimethyl-2,3-diazabuta-1,3-dien) ferrocenophane (VII) have been determined. II exists as a centrosymmetric molecule with eclipsed cyclopentadienyl rings and a planar MeC=NN=CMe bridge whereas VII has staggered cyclopentadienyl rings and non-planar bridges. In II and VII the bridges are in the E,E configuration. The electrochemical results show that the ferrocenium ions of the acetylferrocene and the azines are stable in solution whereas those of the hydrazones are unstable. In agreement with a slightly increasing electronic communication between the two ferrocene units, II undergoes two almost overlapping one-electron oxidations (DeltaE? = 0.09 V) whereas VII displays two more widely separated one-electron oxidations (DeltaE? = 0.12 V).

Combined amperometric/potentiometric probes for improved chemical imaging of corroding surfaces using Scanning Electrochemical Microscopy

Chemical visualization of corrosion processes using scanning electrochemical microscopy (SECM) in combined amperometric/potentiometric operation has been achieved by developing novel multi-barrel probes as tips. A Pt-based amperometric disc probe is employed for the detection and characterization of reactive sites on a corroding system, whereas a Sb-based disc microelectrode is employed to visualize local solution pH changes. Quasi-simultaneous imaging of localized corrosion micro-cells on the surface and the associated pH variations in the electrolyte, resulting from both the electrolysis of dissolved metal ions from the local anodes and the consumption of an oxidizing agent at the local cathodes, can be obtained in the same solution without changing the probe. Galvanic corrosion of a model Cu-Fe pair in chloride-containing solution was visualized with high spatial resolution by recording either line scans or 2D-images using the novel Pt/Sb multi-barrel tip.

Controlled Reduction of Carboxamides to Alcohols or Amines by Zinc Hydrides

New protocols for controlled reduction of carboxamides to either alcohols or amines were established using a combination of sodium hydride (NaH) and zinc halides (ZnX2). Use of a different halide on ZnX2 dictates the selectivity, wherein the NaH-ZnI2 system delivers alcohols and NaH-ZnCl2 gives amines. Extensive mechanistic studies by experimental and theoretical approaches imply that polymeric zinc hydride (ZnH2)? is responsible for alcohol formation, whereas dimeric zinc chloride hydride (H?Zn?Cl)2 is the key species for the production of amines.

Preparation and some chemistry of ferrocenylethynyl ketones

Reactions of Fc?(CHO)2 1 (Fc? = 1,1?-ferrocenediyl) with LiC{triple bond, long}CR gave substituted propargylic alcohols Fc?{CH(OH)C{triple bond, long}CR}2 (R = SiMe3 2, Fc 9). Oxidation (MnO2) of these alcohols afforded the bis(alkynyl ketone)s Fc?{C(O)C{triple bond, long}CR}2 (R = SiMe3 3, Fc 10), the former being accompanied by the partially desilylated Fc?{C(O)C{triple bond, long}CH}-1-{C(O)C{triple bond, long}CSiMe3}-1? 4. The reaction between 4 and RuCl(dppe)Cp in the presence of Na[BPh4] gave the cyclic vinylidene complex [Ru{{double bond, long}C{double bond, long}C[C(O)Fc?C(O)CH{double bond, long}CH]}(dppe)Cp]BPh4 5. The diastereomers were separated by flash chromatography (2) or preparative t.l.c. (9) to give the cis (2a, 9a) and trans (2b, 9b) isomers. Cyclisation of each isomer to the corresponding ferrocenophane was catalysed by pTSA to give Fc?{[CH(C{triple bond, long}CR)]2O} (R = SiMe3 6a, 6b; Fc 11a, 11b), of which 6a, 6b could be desilylated to Fc?{[CH(C{triple bond, long}CH)]2O} 7a, 7b, and further transformed into the bis(eta2-alkyne-dicobalt) complexes Fc?{[CH(eta2-C2H[Co2(mu-dppm)(CO)4])]2O} 8a, 8b with Co2(mu-dppm)(CO)6. Molecular structures of 3, 5, 6a, 6b, 7a, 7b and 10 were determined by single-crystal XRD methods.

A study of the electrochemical reactivity of titanium under cathodic polarization by means of combined feedback and redox competition modes of scanning electrochemical microscopy

The effect of cathodic polarization on the electrochemical behavior of the thin titanium dioxide film formed by anodic pretreatment over pure commercial titanium metal for biomaterial application was investigated in situ using scanning electrochemical microscopy (SECM). Quantitative information on the electron transfer rates (keff) at the titanium surface was obtained using the feedback operation of SECM with ferrocene-methanol (FcMeOH) as electrochemical mediator. An increase of keff values with the increase of the negative polarization was detected, a feature that correlates well with the decrease of titanium oxide resistance with increasing cathodic polarization observed using electrochemical impedance spectroscopy (EIS). In addition, SECM operation in the redox competition mode proved that hydrogen was absorbed in the surface oxide film leading to changes in conductivity and electrochemical reactivity.

Non-cyclic formylated dipyrromethanes as phosphate anion receptors

New tetrakis-and hexakis(1H-pyrrole-2-carbaldehyde) anion receptors are described. The anion binding properties of these receptors were studied in organic media and in the solid state. The receptors displayed good affinity for the dihydrogenphosphate and pyrophosphate anions (as the tetrabutylammonium salts) in chloroform even in the presence of a polar protic solvent, methanol. Solution phase spectroscopic analyses proved consistent with the binding mode seen in single crystal structural studies of the dihydrogenphosphate and pyrophosphate complexes and provided support for the contention that these receptors undergo conformational reorganization in order to accommodate the bound oxoanions both in chloroform solution and in the solid state.

Synthesis of organometallic-based biologically active compounds: In vitro antibacteroial and antifungal of asymmetric ferrocene-derived schiff-bases complexes

A SYMMETRIC 1,1′-disubstituted ferrocene- derived Schiff-bases have been prepared and used as ligands in the preparation of their novel Pd(II) and Pt(IV) metal chelates. The synthesized ligands and their metal chelates have been characterized by their physical, analytical and spectral data. These have also been used for screening against B. subtilis, S. aureus, E. coli, S. typhi (bacteria), C. albicans (yeast), A. niger and F. solani (fungi). The antimicrobial results indicated that the complexes prepared are more active than the ligand and have been found to be a novel class of organometallic-based antimicrobials.
