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.

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.

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.

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.

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.

Highly Diastereo- and Enantioselective Synthesis of Nitrile-Substituted Cyclopropanes by Myoglobin-Mediated Carbene Transfer Catalysis

A chemobiocatalytic strategy for the highly stereoselective synthesis of nitrile-substituted cyclopropanes is reported. The present approach relies on an asymmetric olefin cyclopropanation reaction catalyzed by an engineered myoglobin in the presence of ex situ generated diazoacetonitrile within a compartmentalized reaction system. This method enabled the efficient transformation of a broad range of olefin substrates at a preparative scale with up to 99.9 % de and ee and up to 5600 turnovers. The enzymatic product could be further elaborated to afford a variety of functionalized chiral cyclopropanes. This work expands the range of synthetically valuable, abiotic transformations accessible through biocatalysis and paves the way to the practical and safe exploitation of diazoacetonitrile in biocatalytic carbene transfer reactions.

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.

Structural influences on the electrochemistry of 1,10-di(hydroxyalkyl) ferrocenes. Structure of [Fe{h5-C5H4eCH(OH)e(CH2)3OH}2]

Abstract A series of 1,1′-di(hydroxyalkyl)ferrocenes, [Fc'{(CH 2)nOH}2], with n = 1 (1), 2 (2), 3 (3) and 4 (4) and Fc’ = Fe(eta5-C5H4)2, was synthesized. The electrochemistry of the di(hydroxyalkyl)ferrocenes was studied by cyclic voltammetry in CH2Cl2/0.1 M [N nBu4][PF6] utilizing a glassy carbon working electrode. The ferrocenyl group showed reversible electrochemistry with the formal reduction potential, Eo’ , inversely proportional to alkyl chain length and approximately 59 mV smaller than those of the corresponding mono(hydroxyalkyl)ferrocenes derivatives [Fc(CH2)mOH] with m = 1 (1m), 2 (2m), 3 (3m), and 4 (4m) and Fc = Fe(eta5-C 5H5)(eta5-C5H4 -). The tetraalcohol [Fc'{CH(OH)(CH2)3OH} 2], 5, possessing four OH functionalities, two in the terminal positions and two more, one on each of the two alpha-C relative to the ferrocenyl (Fc’ for dialcohols or Fc for monosubstituted derivatives) group, was isolated as a side product during the synthesis of 4. The formal reduction potential of 5 was Eo’ = -24 mV vs. FcH/FcH+ and closely approached Eo’ of [FcCH(OH)CH3] (Eo’ = -11 mV), [Fc'{CH(OH)CH3}2] (-21 mV) and 1 (0.00 mV vs. FcH/ FcH+). The single crystal X-ray structure of the tetraalcohol 5 (Z = 8, orthorhombic, space group Pbca) was also solved.
