A novel side-chain ferrocene-containing polymer by combination of Cu(0)-mediated SET-LRP of acrylonitrile and post-modification

Well-defined side-chain ferrocene-containing polymers have been synthesized by post-modification of well-defined polyacrylonitrile (PAN). PAN prepared by Cu(0)-mediated single-electron transfer living radical polymerization was further modified using sodium azide and ammonium chloride (NH4Cl) to yield polymeric materials with vinyltetrazole units. Side-chain ferrocene-containing polymer was prepared by vinyltetrazole units and hydroxymethylferrocene after Mitsunobu reaction. FTIR, 1H NMR, UV?Vis spectroscopy and thermogravimetric analysis were used to identify the structure of the target product. After linked the ferrocene unit, the final polymer showed typical redox property?with?a?more negative?redox?potential (E1/2).

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.

Synthesis, structure and enantiomeric resolution of ferrocenylalkyl mercaptoazoles. Antitumor activity in vivo

Ferrocenylalkyl 2-mercaptobenzimidazoles 3 (a-e) and 2-mercaptobenzo[d]thiazole-2(3H)-thiones 5 (a-e) were prepared via the reaction of the alpha-(hydroxy)alkyl ferrocenes, FcCHR(OH) (1a-e; Fc = ferrocenyl; R = H, Me, Et, i-Pr, Ph), either with thiobenzimidazole in acetone at room temperature in the presence of TFA (catalytic amounts), in yields of 55-74%, or with thiobenzothiazole in methylendicloride in presence of aqueous HBF4 (equimolar amounts) at r.t.; in yields of 41-58%. The structures, electrochemical properties and enantiomeric resolution 3a-e and 5a-e (using HPLC on modified amylose as chiral selector) were investigated. In cyclic voltammetry all studied compounds exhibited a reversible one-electron oxidation-reduction wave owing to the ferrocene-ferricenium redox couple with a positive shift (0.56-0.80 V) compared with that of ferrocene (0.50 V). X-ray determinations of molecular structures of 3-ferrocenylmethylbenzo[d]thiazole-2(3H)-thione (5a) 3-ferrocenylethylbenzo[d]thiazole-2(3H)-thione (5b) and 3-ferrocenylphenylmethylbenzo[d]thiazole-2(3H)-thione (5d) were carried out. The toxicity and antitumor activity of N-(ferrocenylethyl)-2-thiobenzimidazole (3b) were evaluated in vivo. Maximum tolerated dose (MTD) value for the compound 3b was found to be equal to 800 mg kg-1. The effectiveness of compound under investigation against murine solid tumor system, carcinoma Ca755 (Ca755), was studied in a wide range of doses and significant antitumor effects were found. The index of tumor growth inhibition (TGI) on Ca755 equaled 87% in comparison with control.

Synthesis of [N,P] ligands based on pyrrole. Application to the total synthesis of arnottin i

This paper describes the synthesis of a new class of [N,P] ligands based on pyrrole with a dimethylamino group as hard donor and a phosphine moiety as soft base. We have also modified the phosphine fragment to change the electronic and steric properties of these ligands. Palladium complex 3a proved to be very efficient in Heck cross-coupling reactions and in intramolecular aryl-aryl couplings of esters and amides. We have demonstrated the applicability and efficiency of this novel catalyst in the total synthesis of the natural product arnottin I.
