APPLICATIONS OF THE QOARTZ CRYSTAL MICROBALANCE TO ELECTROCHEMISTRY. MEASUREMENT OF ION AND SOLVENT POPULATIONS IN THIN FILMS OF POLY(VINYLFERROCENE) AS FUNCTIONS OF REDOX STATE

The quartz crsytal microbalance (QCM) technique is applied to a study of ion and solvent content within poly(vinylferrocene) (PVF) as a function of redox state in various supporting electrolytes.It is concluded that in ClO4(-) and PF6(-) containing electrolytes the oxidation of the film occurs with little and no change in solvent content of the film, respectively.These findings are in agreement with previously postulated phaselike behavior for this system.Multiple peaks are observed in the voltammetry of the PVF film in Cl(-) containing eletrolytes.Based on the concurrent QCM measurements the structure in the voltammetric response is proposed to result from the electrochemically induced dissolution or delamination of the film and a new charge transport (diffusional) situation which results from loss of the film from the surface.The QCM technique is shown to be a powerful tool for the study of process which result in mass changes at solid/liquid interfaces, especially electrode surfaces.

Synthesis of biologically active Co(II), Cu(II), Ni(II), and Zn(II) complexes of symmetrically 1,1?-disubstituted ferrocene-derived compounds

Some novel symmetrically 1,1?-disubstituted ferrocene-derived compounds have been prepared and used as potential ligands for the preparation of Co(II), Cu(II), Ni(II) and Zn(II) metal chelates. The synthesized compounds have been characterized by physical, spectral and analytical data. Screening of these derivatives against pathogenic bacterial species such as Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa and Klebsiella pneumoniae, revealed them to possess bactericidal activity.

Scanning Electrochemical Microscopy (SECM) Investigation of 3D Printed Parts Produced by CMT Welding Technology

In the field of manufacturing technology an exciting revolution is in progress today. The different methods of the so called additive manufacturing (AM) technologies are under fast developments. Several versions of them are called 3D printing. Less interest has been given to study the corrosion resistance character of the differently made 3D printed metal alloy items. In this work corrosion behaviour of 3D printed AlMg4.5Mn0.7 alloy samples were investigated. Conventional methods like open circuit potential measurements, Tafel plots taking and scanning electrochemical microscopy (SECM) ? with pH measuring tungsten micro-tip and micro-disc type Pt electrode were used. The metal samples were embedded in epoxy resin. 2D SECM images and line scans were made to see the local changes of oxygen concentration. Flame atomic absorption spectroscopy was used for measuring the metal composition of manufacturing wire and printed sample. The local activity of the surface spots were measured using approach curves recorded in case of ferrocene methanol mediator.

Synthesis, structure and properties of new ferrocene-containing compounds

The potential use of (aminomethyl)ferrocene and 1,1? -di(aminomethyl)ferrocene as precursor for Schiff base chemistry has been tested. (Aminomethyl)ferrocene reacts with 3,3? -(3-oxapentane-1,5-diyldioxy)bis(2-hydroxybenzaldehyde) to give the [2+1] diiminic ligand 8. 8 reacts with LaCl3 and Ni(CH3COO) 2 giving the corresponding complexes 9 and 10. 1,1? -Di(aminomethyl)ferrocene was prepared by conversion of 1,1? -di(formyl)ferrocene into 1,1?-di(formyl)ferrocene oxime, followed by reduction of the oxime with LiAlH4. Easy degradation of 1,1?-di(aminomethyl)ferrocene prevented its use as aminic precursor for the synthesis of Schiff base ligands. Isomerization occurred about the carbon-nitrogen double bonds of 1,1?-di(formyl)ferrocene oxime giving rise to three isomers. The X-ray analysis has shown that in the 5a complex three independent molecules having different conformation are present.

Synthesis, reactivity and spectroscopy of ferrocene-functionalised porphyrins, with a conjugated connection between the ferrocene and the porphyrin core

Several new ferrocene-functionalised porphyrins and a ruthenocene-functionalised porphyrin have been synthesized and studied using electrochemistry, electronic absorbance and resonance Raman spectroelectrochemical techniques. The porphyrin and ferrocene are observed to have limited effect on each other with the properties of the porphyrin dominating the spectroscopy of these molecules.

Reaction of ferrocenecarbothioamide and N-(ethoxycarbonyl)ferrocenecarbothioamide with alkyl halides

Reaction of ferrocenecarbothioamide and N-(ethoxycarbonyl)ferrocenecarbothioamide with alkyl (mainly benzyl) halides in the presence of K2CO3 has been studied. The former compound yielded cyanoferrocene in high yield whereas the latter was transformed into the corresponding thioimidates as a result of S-alkylation and deprotonation. The molecular structure of S-p-nitrobenzyl-N-(ethoxycarbonyl)-ferrocenethioimidate was determined by single-crystal X-ray analysis and revealed the E configuration. The plausible reaction mechanism is discussed.

Ditopic redox-active polyferrocenyl zinc(II) dithiocarbamate macrocyclic receptors: Synthesis, coordination and electrochemical recognition properties

The synthesis of a range of ditopic polyferrocenyl zinc(II) dithiocarbamate macrocyclic receptors containing ferrocene groups on the macrocycle’s periphery and/or as part of the cyclic cavity is reported. The assemblies have been characterised by a range of spectroscopic techniques, electrochemical studies and in two cases by X-ray structure determination. The ability of these host systems to bind and sense electrochemically anionic guest species, isonicotinate and benzoate, and neutral 4-picoline guest was examined by 1H NMR and cyclic voltammetric titration studies. The strongest association was found between the isonicotinate anion and a dinuclear zinc(II) receptor whose macrocyclic cavity is of complementary size to complex this bidentate guest species in a cooperative manner. Cyclic voltammetric studies demonstrated that all receptors can electrochemically sense the binding of isonicotinate and benzoate via significant cathodic perturbations of the respective ferrocene redox couple.

Rhodium(III)-catalyzed C-H olefination for the Synthesis of ortho-alkenyl phenols using an oxidizing directing group

By using an oxidizing directing group, a mild, efficient Rh(III) catalyzed C-H olefination reaction between N-phenoxyacetamides and alkenes was developed. This reaction provided a straightforward way for the synthesis of ortho-alkenyl phenols, and the directing group is traceless in the product.

Stereo- and enantioselectivity in catalytic hydrogenolysis of chiral substituted ferrocenes to give cyclopentanes

The catalytic hydrogenolysis of 1,2-disubstituted ferrocenes having planar chirality and functional groups such as carboxyl (including ester) or tertiary amino proceeds under mild conditions (1 atm of H2, Pd/C, CF3COOH, 50 deg C) with the retention of functional groups in the cyclopentane products.Stereosectivity has been observed for the examples investigated, the diastereomeric ratio, trans: cis being close to 4:1, but optically inactive products are formed the enantiomeric ferrocenes.In contrast, hydrogenolysis of enantiomeric alpha-(N,N-dimethylamino)ethylferrocene gives an optically active alpha-(N,N-dimethylamino)ethylcyclopentane with retention of configuration at the alpha-carbon, whose bonds are not affected during the hydrogenolysis.
