[reaction: see text] Various ferrocene-based organosilanols have been synthesized in four steps starting from achiral ferrocene carboxylic acid. Applying these novel planar-chiral ferrocenes as catalysts in asymmetric phenyl transfer reactions to substituted benzaldehydes afforded products with high enantiomeric excesses. The best result (91% ee) was achieved in the addition to p-chlorobenzalde...

Abstract Ferrocenium salts can be easily obtained from ferrocene by either synthetic preparation or in situ reaction. The ferrocenium ion can act as a one-electron oxidant and thus initiate or promote a range of radical processes. Ferrocene itself can donate electrons to suitable substrates, resulting in useful transformations. Ferrocenium salts can also act as mild Lewis acids. This paper high...

A novel p-type charge generation material, DPAF, composed of a ferrocene core and a bis(biphenyl)amino group is designed and synthesized for application to tandem OLED devices. This molecular design not only enhances the thermal properties of ferrocene and the hole mobility, but also maintains its electrochemical stability. The red, green, and blue tandem OLEDs all give excellent device perform...

Ferrocene is strongly adsorbed by the highly porous metal-organic framework compound [Al(OH)(bdc)l], (MIL-53; bdc = 1,4-benzenedicarboxylate). The structure of the crystalline phase {[Fe(eta5-C5H5)2][Al(OH)(bdc)]2}x, was determined by X-ray powder diffraction and Rietveld methods. The ferrocene molecules are arranged in a 1D chain-like fashion and their cyclopentadienyl rings are oriented almos...

Cyclic multiredox centered systems are currently of great interest, with new compounds being reported and developments made in understanding their behavior. Efficient, elegant, and high-yielding (for macrocyclic species) synthetic routes to two novel alkynyl-conjugated multiple ferrocene- and biferrocene-containing cyclic compounds are presented. The electronic interactions between the individu...

Several ferrocenylalkynes have been prepared and their reaction with dicobalt octacarbonyl led to the formation of [Co2(CO)6(μ-η 2 : η-ethynylferrocene)] 1, [Co2(CO)6(μ-η 2 : η-1,4-bis(ferrocenyl)butadiyne)] 2, [(Co2(CO)6)2(μ-η : η,μ-η : η-1,4-bis(ferrocenyl)butadiyne)] 3, [Co2(CO)6(μ-η 2 : η-1-ferrocenylethynyl-2-hydro-1,2-dihydro[60]fullerene)] 4, [Co2(CO)6(μ-η 2 : η-1,1’-bis(phenylethynyl)fe...

We report the specific collision of a single murine cytomegalovirus (MCMV) on a platinum ultramicroelectrode (UME, radius of 1 μm). Antibody directed against the viral surface protein glycoprotein B functionalized with glucose oxidase (GOx) allowed for specific detection of the virus in solution and a biological sample (urine). The oxidation of ferrocene methanol to ferrocenium methanol was car...

In  this  work,  a  new  hybrid  organometallic-inorganic  hybrid nanomaterial was prepared by immobilization of acetyl ferrocene on the  surface  of magnetite  nanoparticles. Covalent  grafting of silica coated magnetite nanoparticles (SCMNPs) with 3-aminopropyl triethoxysilane gave aminopropyl-modified magnetite nanoparticles (AmpSCMNPs). Then, Schiff base condensation  of AmpSCMNPs with acet...
