Preparation of cyclopentadienyltricarbonylrhenium complexes using a double ligand-transfer reaction

A unique double ligand-transfer reaction is described for the preparation of substituted cyclopentadienyltricarbonylrhenium complexes. In the reaction, potassium perrhenate(VII) is reduced and carbonylated by treatment with chromium trichloride and chromium hexacarbonyl to provide a proposed alkoxy carbonyl rhenium(I) intermediate. It is believed that this intermediate then undergoes a Cp ligand-transfer reaction with an acyl-substituted ferrocene to provide the corresponding (acyl-cyclopentadienyl)tricarbonylrhenium complex. A strongly coordinating solvent such as methanol is necessary to promote the reduction of perrhenate, and a carbonyl substituent conjugated to the Cp ring is necessary to activate it for transfer from iron to rhenium. This method has potential value for the synthesis of rhenium and technetium organometallic radiopharmaceuticals.

The synthesis and properties of ferroceno[1?,2?;1?,2?]bis(1,3-dithiol-2-thione and -2-one) derivatives

The t-butyl and bis(t-butyl) derivatives of hexathia[3.3]ferrocenophane were prepared from the corresponding trithia[3]ferrocenophanes. The former was a mixture of chair-chair and chair-boat isomers, and the latter existed only chair-boat isomer. The hexathia[3.3]ferrocenophanes were led to the tetrathiols with LiAlH4, which allowed to react with 1,1?-thiocarbonyldiimidazol to give the corresponding ferroceno[1?,2?;1?,2?]bis(1,3-dithiol-2-thione) derivatives. Mono t-butyl and unsubstituted analogs were prepared in a similar manner. The X-ray structural determination showed that these derivatives adopted the conformation in which the 1,3-dithiol-2-thione rings were heaped on top of each other. In the crystal of ferroceno[1?,2?;1?,2?]bis(1,3-dithiol-2-thione), the molecules packed so as to put the axis of molecule in order and to overlap one another above and below. The desulfurizative coupling of the ferroceno[1?,2?;1?,2?]bis(1,3-dithiol-2-thione) derivatives was unsuccessful.

Electrochemical Collisions of Individual Graphene Oxide Sheets: An Analytical and Fundamental Study

We propose an analytical method based on electrochemical collisions to detect individual graphene oxide (GO) sheets in an aqueous suspension. The collision rate is found to exhibit a complex dependence on redox mediator and supporting electrolyte concentrations. The analysis of multiple collision events in conjunction with numerical simulations allows quantitative information to be extracted, such as the molar concentration of GO sheets in suspension and an estimate of the size of individual sheets. We also evidence by numerical simulation the existence of edge effects on a 2D blocking object.

Syntheses, Crystal Structures, and Properties of Two d 10 Metal Complexes Based on Ferrocenyl Ligands Bearing Pyrazolyl Pyridine Substituents

Two new complexes, namely, [Cd2(L1)2(NCS)4(DMF)2] ¡¤ 4H2O (I) and {[Zn3(L2)4(SO4)3(H2O)8] ¡¤ 3DMF ¡¤ 6H2O}n (II) have been synthesized through self-assembly of Cd(II) or Zn(II) salts with ferrocenyl ligands bearing pyrazolyl pyridine substituents. The two compounds were characterized by IR spectra, element analysis, X-ray powder diffraction, single-crystal X-ray diffraction (?IF files CCDC nos. 949526 (I), 949527 (II)), and thermogravimetric analysis. Complex I crystallizes in the monocline space group P21/c and exhibits a discrete dinuclear structure. The adjacent dinuclear molecules are packed into a 1D linear chain through the hydrogen-bond interactions. Complex II is a neutral one-dimensional infinite zigzag coordination chain. The 3D packing diagram of II contains two types of voids and the solvated DMF and water molecules filled them and stabilized by the hydrogen bonds. In addition, the redox properties of both complexes I and II have also been investigated.

Mechanochemical synthesis and spectroscopic properties of 1,1′-ferrocenyldiacrylonitriles: The effect of para -substituents

An efficient and simple solvent-free mechanochemical approach for the synthesis of 1,1′-ferrocenyldiacrylonitriles was achieved by grinding together 1,1′-ferrocenedicarboxaldehyde (1) and phenylacetonitriles. A range of 1,1′-ferrocenyldiacrylonitriles and ferrocenylacrylonitriles (2-7) were synthesized within short reaction times, with water as the only by-product. In a similar manner, grinding together ferrocenemonocarboxaldehyde (8) and phenylenediacetonitrile yielded phenylene-3,3′-bis-(ferrocenyl)diacrylonitrile (9) and 3-ferrocenyl-2-(acetonitrophenyl)acrylonitrile (10). The yield and selectivity towards formation of ferrocenyldiacrylonitriles was strongly influenced by the electronegativity of the para-substituent on the phenyl ring of phenylacetonitriles. The compounds were characterized using NMR, IR, and UV-visible spectroscopy and HR-MS. Cyclic voltammetry measurements of selected compounds highlighted the role of ligands in tuning the electrochemical properties of 1,1′-ferrocenyldiacrylonitriles. X-ray crystallographic analysis highlighted the effect of the electronegativity of the para-substituent on the conformation of cyclopentadienyl rings attached to a ferrocenyl moiety.

Bis(methoxypropyl) ether-promoted oxidation of aromatic alcohols into aromatic carboxylic acids and aromatic ketones with O2 under metal- and base-free conditions

We describe an eco-friendly, practical and operationally simple procedure for the bis(methoxypropyl) ether-promoted oxidation of aromatic alcohols into aromatic carboxylic acids and aromatic ketones with atmospheric dioxygen as the sole oxidant. This chemical process is clean with high conversion and good selectivity, and an external initiator, catalyst, additive and base are not required. The virtue of this reaction is highlighted by its easily available and economical raw materials and excellent functional group tolerance (acid-, base- and oxidant-labile groups).

Development of a bioelectrode fabricated with a multilayer thin film of poly(diallyldimethylammonium)/gold-nanoparticle/lactate oxidase for analysis of L-lactate in food samples

Multilayer films made of poly(diallyldimethylammonium) (PDDA), gold nanoparticles (AuNP) of 10?nm diameter and lactate oxidase (LOx), were built for the first time, by layer-by-layer (LBL) assembly technique onto both quartz and gold substrates. The surface plasmon resonance (SPR) band of AuNP was used for monitoring the film growth and adsorption kinetics on PDDA monolayer supported onto quartz substrate. In the case of polycrystalline gold surfaces, electrochemical characterization was performed by means of cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS). The latter system was used as bioelectrode for L-lactate quantification, showing a short time response (<10?s) with high sensitivity of 63?¡À?3?muA?mM?1cm?2, detection limit of 0.47?muM and linear range between 0.001?mM and 0.25?mM. This bioelectrode was also tested for L-lactate analysis in yogurt and fermented milk, and it was checked that typical interfering as glucose and citric, acetic and ascorbic acids do not play a role. Present results indicate that self-assembled multilayers made of PDDA/AuNP/LOx are suitable thin films for electroanalytical determination of L-lactate in real samples.

Heme-coordinated histidine residues form non-specific functional “ferritin-heme” peroxidase system: Possible and partial mechanistic relevance to oxidative stress-mediated pathology in neurodegenerative diseases

Ferritin is a giant protein composed of 24 subunits which is able to sequester up to 4500 atoms of iron. We proposed two kinds of heme binding sites in mammalian ferritins and provided direct evidence for peroxidase activity of heme-ferritin, since there is the possibility that “ferritin-heme” systems display unexpected catalytic behavior like heme-containing enzymes. In the current study, peroxidase activity of heme-bound ferritin was studied using TMB1, l-DOPA, serotonin, and dopamine, in the presence of H2O2, as oxidant substrate. The catalytic oxidation of TMB was consistent with first-order kinetics with respect to ferritin concentration. Perturbation of the binding affinity and catalytic behavior of heme-bound His-modified ferritin were also documented. We also discuss the importance of the peroxidase-/nitrative-mediated oxidation of vital molecules as well as ferritin-induced catalase inhibition using in vitro experimental system. Uncontrollable “heme-ferritin”-based enzyme activity as well as up-regulation of heme and ferritin may inspire that some oxidative stress-mediated cytotoxic effects in AD-affected cells could be correlated to ferritin-heme interaction and/or ferritin-induced catalase inhibition and describe its contribution as an important causative pathogenesis mechanism in some neurodegenerative disorders.
