Synthesis, chemical reactivity and electrochemical behaviour of mono- and difluoro metallocenes

We report the synthesis of mono- and 1,1?-difluoro-substituted metallocenes (ferrocene, ruthenocene) and of asymmetrical 1,1?-disubstituted ferrocenes with one substituent being fluorine. Lithiation of metallocenes and subsequent addition of the fluorinating agent NFSI gave the fluorinated metallocenes after optimization of the experimental conditions. All new compounds were comprehensively characterized and the cyclic voltammograms of fluoro- and 1,1?-difluoroferrocene were recorded and compared to other mono- and dihalogenated ferrocenes. Half-wave potentials of +106 mV and +220 mV vs. FcH0/+ were obtained for monofluorinated species and difluorinated ferrocene, respectively. Both values are remarkably low compared to the other halogenated ferrocenes (Cl, Br, and I). Finally, 1-bromo-1′-fluoro-ferrocene turns out to be an ideal starting material for further fluoro-substituted ferrocene derivatives.

Anion recognition by highly sterically encumbered 1,2-diborylferrocenes

The syntheses and structural characterization of sterically encumbered 1,2-diborylferrocenes are reported, together with an investigation of their anion recognition capabilities with respect to fluoride and cyanide. Surprisingly, 1,2-fc(BMes2)2 is found to be highly selective for CN-, with the uptake of F- being shown to be not only thermodynamically less favorable but also kinetically much slower.

Detection of proteins on membranes and in microchannels using copper staining combined with scanning electrochemical microscopy

Scanning electrochemical microscopy (SECM) and copper staining are combined to achieve visualisation of proteins on surfaces. Proteins are adsorbed on a polyvinylidene fluoride (PVDF) membrane or on a polyethylene terephthalate (PET) surface and stained using a standard protocol involving copper salts. Salts are then reduced to copper and detected by SECM with ferrocene methanol as a redox mediator in aqueous solution. During the SECM scan, the potential is held at a value at which the oxidation of the redox mediator occurs and a positive feedback current is detected when scanning over copper clusters. A negative feedback is observed elsewhere. This method enables unspecific protein adsorption mapping on polymeric membranes and into microchannels without any requirement of enzymatic activity or affinity to a labelled secondary reporter.

Noncovalent linkage of telechelic oligo(dimethylsiloxanes) via end group attachment of host-cyclodextrins and guest-adamantanes or guest-ferrocenes

In this article, we report the noncovalent linkage of terminal substituted oligo(dimethylsiloxanes) bearing cyclodextrins (CD) as host endgroups and adamantan or ferrocene, respectively, as guest endgroups. Structural characterization was performed by 1H NMR-, IR-, and mass spectroscopy. Electron microscopy studies show significant differences in the surface structure of the individual derivatives. In addition, the ferrocene-terminated di-and poly(dimethylsiloxanes) are distinguished by a red-ox activity and reversibility, which also makes the complexes between the ferrocene- and CD functionalized siloxanes switchable via electrochemical stimuli. The evidence for a successful complexation of the end groups, and thus the successful supramolecular formation of the siloxane strands, was even performed by shift of the protons in the 1H NMR spectra.

The reactions of acylferrocenes with samarium diiodide: Reduction, deoxygenation, reductive coupling and rearrangement

Acylferrocenes reacted with samarium diiodide in the presence of water to give the corresponding (alpha-hydroxyalkyl)ferrocenes or alkylferrocenes depending on the reaction time and temperature. On treatment with samarium diiodide in the absence of water, ferrocenecarbaldehyde underwent a reductive coupling to give pinacols, whereas acetylferrocene yielded 3,3-diferrocenyl-2-butanone and 2,3-diferrocenyl-2-butene via the subsequent rearrangement and deoxygenation.

Synthesis, characterization and antimicrobial evaluation of mono- and polynuclear ferrocenyl-derived amino and imino complexes

A series of ferrocenyl mono- and polynuclear complexes conjugated to imino and amino scaffolds was prepared. The imino complexes were prepared via a Schiff base condensation reaction between (E)-4-vinylferrocenylbenzaldehyde and various amines. The amino complexes were prepared by reductive amination reactions using the same precursors. The compounds were characterized using standard spectroscopic and analytical techniques including Nuclear Magnetic Resonance (NMR) spectroscopy, Infrared (IR) spectroscopy and mass spectrometry. The compounds were screened against Mycobacterium tuberculosis as well as the NF54 chloroquine-sensitive (CQS) strain of Plasmodium falciparum. Overall, the complexes showed moderate in vitro biological activity, with the ferrocenylimines exhibiting enhanced activity against M. tuberculosis compared to the corresponding amines. The ferrocenylimines also displayed moderate activity against P. falciparum, with the second-generation polyimine complex exhibiting the highest activity in vitro. The ferrocenylamines exhibit promising antiplasmodial activity, enhanced compared to the imines, with the silicon-containing derivative and the second-generation dendrimer showing good activity.

Carbosilane-supported (p-cymene) ruthenium ferrocenyl phosphines in the beta-oxopropyl ester synthesis

The synthesis and characterization of a series of carbosilane-supported ferrocenyl phosphine ruthenium complexes of type SiMe4-n(Fe(eta5-C5H4SiMe2(CH2)3)((eta5-C5H4PR2)RuCl2(eta6-p-cymene)))n (p-cymene = 1-i-Pr-4-Me-C6H4; n = 2: 10a, R = Ph; 10b, R = cC6H11; 10c, R = 2-(5-Me)C4H2O); n = 4: 11a, R = Ph; 11b, R = cC6H11; 11c, R = 2-(5-Me)C4H2O)) is described. For comparative reasons, the non-immobilized ferrocenyl phosphine ruthenium complexes [FcPR2(RuCl2(eta6-p-cymene))] (Fc = Fe(eta5-C5H4)(eta5-C5H5); 9a, R = Ph; 9b, R = cC6H11; 9c, R = 2-(5-Me)C4H2O) were prepared. The molecular structure of 9c in the solid state is reported confirming the expected tetrahedral coordination sphere about the phosphorus atom and the “piano-stool” geometry about ruthenium. The ruthenium complexes 9-11 are catalytically active in the addition of benzoic acid to propargyl alcohol to form beta-oxopropyl benzoate. The obtained activities and productivities show that a good solubility of the catalyst is necessary for a successful catalytic reaction. Furthermore, the rate of the reaction can be influenced by using less basic and electron-withdrawing phosphine ligands.
