This paper describes the electrocatalytic effect of polyphenosafranin films on the oxidation of 1,1′-ferrocenedimethanol (FM). Electrode modification with the polymer raised the voltammetric current of FM in its dilute solutions markedly. This effect arose from the preconcentration of FM on ele...

2-Hydroxypropyl-β-cyclodextrin (HPBC) was used to enclose 1,1′-dimethylferrocene (DMF) into its hydrophobic cavity to form a yellow water-soluble complex with a molar ratio of about 6 to 1. The cyclic voltammogram of the complex solution exhibited one single electron transfer process with a ha...

Nitric oxide (NO) released from cells or other sources is very rapidly oxidized to nitrite in the presence of oxygen. This article describes a procedure utilizing 1,1′-dimethylferrocene as the reducing agent for nitrite to nitric oxide and its subsequent determination by chemiluminescence. The ...

Bilirubin oxidase, a commercially available copper-containing enzyme isolated from Myrothecium verrucaria, was observed to oxidize a yellow 1,1′-dimethylferrocene-2-hydroxypropyl-β-cyclodextrin inclusion complex to a stable blue dye known as 1,1′-dimethylferricinium at pH 5–7. During the oxi...

Cyclic voltammetric oxidation of 1,1′-dimethylferrocene (DMFc) at an Au disc electrode in dichloromethane, 1,4-dichlorobutane, 1,6-dichlorohexane, chlorobenzene, 1,2-dichlorobenzene, 1,2-dichloroethane, 2-nitrophenyl octyl ether and nitrobenzene is used to estimate the standard potential E0(SHE...

An electron-mediated glucose biosensor was constructed from spectroscopic-grade graphite electrodes in three steps. A non-conducting electropolymerized film serves to screen out electroactive interferents and prevents electrode fouling. The electron mediator 1,1′-dimethylferrocene is adsorbed o...

Syntheses of diastereomeric mixtures of 1,1′-dimethylferrocene-2-Ala-OMe (3) and 1,1′-dimethylferrocene-3-Ala-OMe (4) are reported by peptide coupling of L-Ala-OMe to the enantiomeric mixtures of the corresponding acids, 1,1′-dimethylferrocene-2-carboxylic acid (1) and 1,1′-dimethylferrocene...

Heterogeneous nanoparticle NA-MgO-MAO/NA-TiO2 (anatase)-MAO supported bis (cyclopentadienyl) zirconium dichloride (Cp2ZrCl2) are synthesized and used for the polymerization of styrene monomer. The supporting process is confirmed via X-ray photoelectron spectroscopy (XPS) and FTIR. Characterizati...

Planar chirality has been introduced into chiral ferrocenecarboxamides via an amide-directed ortho-lithiation with diastereoselectivity of up to 99%. The use of an easily accessible, camphane-based chiral auxiliary as an ortho-directing group led to single diastereoisomers with a variety of elec...

This work reports the first method for the synthesis of α-hydroxyphosphonates from aldehydes catalyzed by cyclopentadienyl ruthenium(II) complexes. The best results were obtained using the system HP(O)(OEt)2/[RuClCp(PPh3)2] (5 mol%), affording the α-hydroxyphosphonates in good to excellent yie...

Reactions of SiMe3(N3) with Ru(CCH)(PP)Cp’ [PP = (PPh3)2, Cp′ = Cp; PP = dppe, Cp′ = Cp*] afford Ru(N3)(PP)Cp′. Reactions of Ru(CCCCR)(dppe)Cp* with SiMe3(N3) give Ru{N3C(CN)CH2R}(dppe)Cp* (R = H 2, Ph 3). With RuCl(dppe)Cp* in the presence of [NH4]PF6, 2 gives binuclear [Cp*(dppe)Ru{N3C[{(C...

The effect of the oxygen exposure on ruthenium atomic layer deposition (ALD) was investigated. Ru ALD was carried out using bis(cyclopentadienyl)ruthenium and oxygen gas. To investigate the effect of the oxygen exposure, the total oxygen exposure was changed by two different ways; change of expo...

A new crystalline polymorph of known chloro(cyclopentadienyl)bis(triphenylphosphine)ruthenium(II) complex [RuCl(PPh3)2(η5-C5H5)] was obtained and characterized by various analytical methods including single-crystal and powder X-ray diffraction (XRPD) and differential scanning calorimetry (DSC) ...

Cyclopentadienyl ruthenium complexes bearing mixed heterocyclic thiol and bis(diphenylphsphino)ferrocene (dppf) ligands are presented. The complex-salts [CpRu(dppf)(κ1S-HS-het)]PF6 {Cp = η5-C5H5; HS-het = 2-mercaptobenzothiazole (1), 2-mercaptobenzimidazole (2)} were synthesized from the react...

Magnesium surface dope with vanadium has been considered as one of the best material for the hydrogen storage application. Optimization of vanadium concentration doping is important to retain the hydrogen storage capacity above 6 wt %. Vanadocene, bis(η5-cyclopentadienyl) vanadium, with the for...

The electronic spectra of solid MgCp2 (Cp = cyclopentadienyl) show features which indicate the presence of intramolecular interligand interactions. The fluorescence of MgCp2 (λmax = 363 nm) undergoes a considerable Stokes shift which is apparently caused by a bonding attraction between both Cp ...

Bis(cyclopentadienyl) nickel II is one of the best precursors of nickel catalyst which remarkably improved the hydrogen absorption-desorption of Mg–MgH2 system. The X-ray photoelectron spectroscopy (XPS) and Furrier Transformed Infrared Spectroscopy (FTIR) analyses revealed that bis (cyclopenta...
