A carbon paste electrode was modified with the ionic liquid 1-methyl-3-octyl imidazolium hexafluorophosphate and it was applied for study the electrocatalytic oxidation and voltammetric determination of the drug sulfamethazine. The developed modified electrode was characterized using cyclic voltammetry and scanning electron microscopy. The oxidation of sulfamethazine at the surface of modified electrode occurs at lower potentials than that of an unmodified carbon paste electrode, and both an enhancement of the anodic peak current and a signal narrower and better defined with the modified electrode were observed. Accordingly, a method for the determination of sulfamethazine was developed using differential pulse voltammetry, at pH 11 and with an accumulation time of 3 min. The oxidation of sulfamethazine exhibited a dynamic range between 30 and 300 mug/mL and detection and quantitation limits of 54 and 61 mug/mL, respectively. The method was applied to the determination of sulfamethazine in a veterinary commercial solution.

Electric Literature of 1293-65-8, Enzyme inhibitors cause a decrease in the reaction rate of an enzyme-catalyzed reaction by binding to a specific portion of an enzyme and thus slowing or preventing a reaction from occurring. 1293-65-8, Name is 1,1′-Dibromoferrocene, molecular weight is 335.76. molecular formula is C10Br2Fe.

Palladium(II) and nickel(II) halide complexes of the ferrocenyl polyphosphines 1,1?,2,3-tetrakis(diphenylphosphino)ferrocene (1), and 1,1?,2-tris(diphenylphosphino)-4-tert-butylferrocene (5) were prepared and characterized by multinuclear NMR. The metallo-ligand 1, the palladium [Pd 2Cl4(1)] (3b) and nickel [NiCl2(5)] (6) coordination complexes were additionally characterized by X-ray diffraction crystallography. The behavior of 1 toward coordination to nickel and palladium was surprisingly different because the coordination of a second metal center after the initial 1,2-phosphorus-bonding of nickel was markedly difficult. The preference of nickel for 1,2-P coordination on 1,1?-bonding was confirmed by the exclusive formation of 6 from 5. The changes noted between the solid state structure of the ligand 1 and the structure obtained for the dinuclear palladium complex 3b reveal the rotational flexibility of this tetraphosphine. This flexibility is at the origin of the unique framework for a metallocenic dinuclear metal complex in which both coexist a 1,1?-heteroannular chelating P-bonding and a 2,3-homoannular chelating P-bonding with two palladium centers. Some reported specimens of ferrocenyl polyphosphines of constrained geometry have previously revealed that phosphorus lone pair overlap can lead to very intense “through-space” 31P31P nuclear spin-spin coupling constants (JPP) (J. Am. Chem. Soc. 2004, 126 (35), 11077-11087] in solution phase. In these cases, an intemuclear distance between heteroannular phosphorus atoms below 4.9 A, with an adequate orientation of the lone-pairs in the solid state and in solution, was a necessary parameter. The flexibility of the new polyphosphines 1 and 5 does not allow that spatial proximity (intemuclear distances between heteroannular phosphorus above 5.2 A in the solid state); accordingly the expected through-space nuclear spin-spin coupling constants were not detected in any of their coordination complexes nor in 1.

The surface of a platinum electrode has been modified with platinum nanoparticles (PtNPs) and the enzyme sulfite oxidase (SOx), was entrapped on its surface in an ultrathin polypyrrole (PPy) film. The PtNPs, with a diameter of 30?40 nm, were deposited on the Pt electrode by cycling the electrode potential 20 times from -200 to 200 mV at a sweep rate of 50 mV.s-1. Morphological evidence of the successful incorporation of SOx and the presence of PtNPs were obtained by scanning electron microscopy. Also, the electrochemical behavior of the PtNPs/PPy-SOx film was examined by cyclic voltammetry, chronopotentiometry, electrochemical impedance spectroscopy and potentiometry. Under optimized conditions, the biosensor achieved a sensitivity of 57.5 mV.decade-1, a linear response that extends from 0.75 to 65 muM of sulfite, a detection limit of 12.4 nM, and a response time of 3?5 s. The biosensor was successfully applied to the determination of sulfite in wine and beer samples. [Figure not available: see fulltext.]

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).

Biomolecules are integral constituents of living beings which regulate numerous biochemical functions of the body. Analysis of various small molecules (metabolites, neurotransmitters, amino acids, vitamins) and macromolecules (nucleic acids, proteins) is of prime importance in modern time due to increasing disbalance in natural metabolism of human body. Irregularities and alteration in concentration of biomolecules lead to different kinds of genetic, metabolic and cancerous diseases which have created a great requirement of highly sensitive, accurate and stable detection systems for their quick and specific screening. In this review, redox interactions of biomolecules at carbon based electrode interfaces have been discussed using voltammetry. It is divided into subsections, starting with an introduction into the field and a description of its current state. This is followed by a large section describing carbon nanomaterials (CNs) based voltammetric sensors for different small biomolecules and macromolecules. The next section of the review gives conclusion, challenges and future perspectives in sensing biomolecules at CNs based electrodes. Advanced approaches for fabrication of portable integrated electrochemical devices for various point of care diagnostic applications have also been included at the end.

The super electrophilicity of a shelf-stable, easily prepared trifluoromethylthiolating reagent N-trifluoromethylthio-dibenzenesulfonimide 7 was demonstrated. Consistent with the theoretical prediction, 7 exhibits reactivity remarkably higher than that of other known electrophilic trifluoromethylthiolating reagents. In the absence of any additive, 7 reacted with a wide range of electron-rich arenes and activated heteroarenes under mild conditions. Likewise, reactions of 7 with styrene derivatives can be fine-tuned by simply changing the reaction solvents to generate trifluoromethylthiolated styrenes or oxo-trifluoromethylthio or amino-trifluoromethylthio difunctionalized compounds in high yields.

Related Products of 1271-48-3, In heterogeneous catalysis, catalysts provide a surface to which reactants bind in a process of adsorption. In homogeneous catalysis, catalysts are in the same phase as the reactants. In a document type is Article, and a compound is mentioned, 1271-48-3, name is 1,1′-Ferrocenedicarboxaldehyde, introducing its new discovery.

[1+1], [1+2], [2+1] or [3+1] acyclic and [1+1] or [2+2] cyclic Schiff bases (LALS), containing ferrocene moieties, have been prepared by reaction of formyl- or 1,1?-diformylferrocene and the appropriate amines. Formyl- and 1,1-diformylferrocene form respectively the acyclic [2+1] LW and [2+2]n LZ compounds by reaction with 1,4-diaminomethylbenzene. Similar compounds (LTLV) have been obtained by condensation of aminomethylferrocene and 2,6-diformylpyridine, 2,6-diformyl-4-chlorophenol and 3-methoxy-2-hydroxybenzaldehyde. By reduction of these compounds with NaBH4 the corresponding ferrocene-amine derivatives (L?) have been synthesized. All these compounds have been characterized by physico-chemical measurements (IR, NMR, Moessbauer spectroscopy and FAB mass spectrometry) and LH, derived by the condensation of ferrocene-aldehyde and 1,5-diamino-3-oxa-pentane, also by an X-ray structural determination. The X-ray analysis of crystals of LH, grown from a diethyl ether solution, shows that two independent molecules are present in the asymmetric unit; these two molecules are chemically equivalent with the ferrocenyl groups in the eclipsed form. The coordination ability of these compounds towards d metal ions as copper(II), nickel(II), platinum(II) and rhodium(III) was investigated; while the Schiff bases (L) may suffer hydrolysis, their reduced analogues (L?) form stable, well-defined complexes of the type M(L?)(Cl)n (n=2, 3). The Moessbauer spectra of the prepared compounds show signals with delta at 0.44 and DeltaEQ 2.30 mm s-1 for the Schiff bases LALS and 0.52 and 2.40 mm s-1 for the reduced analogues and hence may be diagnostic of the presence of Fe-CH=N- or Fe-CH2-NH- groups. The signals with delta at 0.51-0.55 and DeltaEQ at 2.34-2.38 mm s-1 for the Schiff bases LTLV, having Fe-CH2-N=CH groups, resemble those of the reduced analogues.

Ferrocene and ferrocenium sites in radiofrequency plasma polymer films on Pt electrodes can be electrochemically oxidized and re-reduced in contact with a variety of electrolyte/solvent systems.When the electrochemical reaction is conducted under near-equilibrium conditions, cyclic voltammetric and chronopotentiometric waveshapes reflect the modulation of ferrocene and ferrocenium site activities by solvent swelling of the film.In water, ferrocene sites exhibit a phase-like (constant) activity during film oxidation, but in acetonitrile ferrocene site activity is proportional to fractional film oxidation.When the film oxidation or reduction is driven by a large potential step (avoiding film ohmic resistance effects), the rate of film reaction is controlled by Fickian diffusion of electrochemical charge through the film.In water, the product of charge diffusion constant and initial concentration of electroactive sites, D1/2C, is 2 X 10-8 mol/cm2 s1/2 for film oxidation and 1.4 X 10-8 mol/cm2 s1/2 for film re-reduction.The difference may be due greater film swelling in the oxidized state.The relationship of charge diffusion rates in redox polymer films on electrodes to their electrocatalytic reactions is discussed.
