An effective mild procedure for the reductive deoxygenation of alpha-ferrocenyl aldehydes, ketones, and alcohols into the corresponding alkylferrocenes is described using a combination of zinc borohydride and zinc chloride. This is the first example of such reactivity of zinc borohydride. The present method allows the synthesis of alkylferrocenes bearing terminally functionalized pendant chains.

The prevalence of solvent effects in heterogeneous catalysis in condensed media has motivated developing theoretical assessments of solvent structures and their interactions with reaction intermediates and transition states.

The synthesis of heterocyclic systems incorporating more than one ferrocene unit was shown to be a facile and convenient route for the synthesis of new ferrocene-heterocycles. Hydrazide 2 was prepared and cyclized to oxadiazole, triazole, and pyrazole using the procedures described in this context with good yields. A pyrazolone derivative could not be obtained and instead a hydrazone derivative 17 was isolated. Hydrazide 2 was condensed with aromatic aldehydes and ferrocene-1,1?-dicarbaldehyde derivatives to give the corresponding hydrazones 11a-c and dihydrazones 12, 14 and 18 in high yields. Cyclic voltammetry (CV) of the selected ferrocene-heterocycles 8 and 9 was studied comparing with the parent ferrocene and acetylferrocene. The CV of the compound 8 revealed an additional, quasireversible, one-electron oxidation wave at 849 mV, corresponding to the second ferrocene unit connected to the oxadiazole ring through the SCH2CO spacer.

Unsymmetrical 1,1?-disubstituted ferrocenes bearing an amino acid moiety and a conjugated electron density controlling substituent were synthesized conveniently starting from 1,1?-ferrocenedicarbaldehyde. The novel ferrocene amino acid derivatives were completely characterized from their MS, 1H NMR and 13C NMR spectra. Their electrochemical behavior was studied by cyclic voltammetry. Their formal redox potentials Ef were slightly influenced by the nature of the amino acid and mainly by the kind of the ethenyl substituent. Furthermore all the (Z)-isomers exhibited a slight anodic shift compared with the corresponding (E)-isomers.

This work reports the successful application of bamboo-like multiwalled carbon nanotubes (bCNT) non-covalently functionalized with calf-thymus double stranded DNA (dsDNA) as a robust platform (bCNT-dsDNA) to build electrochemical biosensors. The “model system” proposed here as a proof of concept was an enzymatic biosensor devoted to glucose quantification obtained by layer-by-layer self-assemby of polydiallyldimethylammonium (PDDA) and glucose oxidase (GOx) at glassy carbon electrodes (GCE) modified with bCNT-dsDNA (GCE/bCNT-dsDNA/(PDDA/GOx)n). The influence of GOx and PDDA assembling conditions and the effect of the number of PDDA/GOx bilayers (n) on the performance of the resulting biosensor is critically discussed. The supramolecular architecture was characterized by electrochemical impedance spectroscopy from the charge transfer resistance of quinone/hydroquinone and potassium ferrocyanide/potassium ferricyanide; by cyclic voltammetry from the surface concentration of GOx using ferrocene methanol as enzyme regenerator; by amperometry from the response of the enzymatically generated hydrogen peroxide; and by surface plasmon resonance from the changes in the plasmon resonance angle. The analytical parameters obtained with GCE/bCNT-dsDNA/(PDDA/GOx)3 for the amperometric quantification of glucose at 0.700 V were: sensitivity of (265 ± 7) muA mM-1 cm-2, linear range between 0.25 and 2.50 × 10-3 M, detection limit of 50 muM, repeatability of 3.6% (n = 10), and negligible interference from maltose, galactose, fructose and manose. The biosensor was successfully used for the sensitive quantification of glucose in beverages and a medicine sample.

Chemistry involves the study of all things chemical – chemical processes, COA of Formula: C11H3FeO, chemical compositions and chemical manipulation – in order to better understand the way in which materials are structured, how they change and how they react in certain situations. In a patent，Which mentioned a new discovery about 1273-86-5

A series of redox-labeled L-tyrosinamide (L-Tym) derivatives was prepared and the nature of the functional group and the chain length of the spacer were systematically varied in a step-by-step affinity optimization process of the tracer for the L-Tym aptamer. The choice of the labeling position on L-Tym proved to be crucial for the molecular recognition event, which could be monitored by cyclic voltammetry and is based on the different diffusion rates of free and bound targets in solution. From this screening approach an efficient electroactive tracer emerged. Comparable dissociation constants Kd were obtained for the unlabeled and labeled targets in direct or competitive binding assays. The enantiomeric tracer was prepared and its enantioselective recognition by the corresponding anti-D-Tym aptamer was demonstrated. The access to both enantiomeric tracer molecules opens the door for the development of one-pot determination of the enantiomeric excess when using different labels with well-separated redox potentials for each enantiomer. Trace compounds: Redox tracers have been synthesized for enantioselective electrochemical ligand binding assays by relying on the combined use of an oligonucleotide-aptamer receptor with the detection of the redox label. A rational step-by-step optimization procedure has been developed leading to a redox-labeled L-tyrosinamide derivative (see figure) conserving the high affinity towards the aptamer.

The result showed that such a combination of chemo- and biocatalysis improved the catalytic yield more than two times compared with that of sole metal catalysis. We will look forword to the important role of 1273-86-5, and how the biochemistry of the body works.COA of Formula: C11H3FeO

Introducing a new discovery about 1273-94-5, Name is 1,1′-Diacetylferrocene

Interfacial energetics for n-type MoSe2 (Eg = 1.4 eV, direct) and photoelectrochemical conversion of light to electrical energy in the presence of Xn-/X- (X = Cl, Br, I) have been characterized in CH3CN electrolyte solution.Data for MoSe2 in H2O/I3-/I- are included for comparison, along with a comparison of MoSe2-based cells with MoS2- (Eg = 1.7 eV, direct) based cells.Cyclic voltammetry for a set of reversible (at Pt electrodes) redox couples whose formal potential, <*>, spans a range -0.8 to +1.5 V vs.SCE has been employed to establish the interface energetics of MoSe2.For the redox couples having <*> more negative than ca. -0.1 V vs.SCE, we find reversible electrochemistry in the dark at n-type MoSe2.When <*> is somewhat positive of -0.1 V vs.SCE, we find that oxidation of the reduced form of the redox couple can be effected in an uphill sense by irradiation of the n-type MoSe2 with <*>Eg light; the anodic current peak is at more negative potential than at Pt for such situations.The extent to which the photoanodic current peak is more negative than at Pt is a measure of the output photovoltage for a given couple.For <*> more positive than ca. +0.7 V vs.SCE it would appear that this output photovoltage is constant at ca. 0.4 V.For a redox couple such as biferrocene (<*>(BF+/BF) = +0.3 V vs.SCE) we find a photoanodic current onset at ca. -0.2 V vs.SCE; a redox couple with <*> = 1.5 V vs.SCE shows an output photovoltage of 0.43 V under the same conditions.The ability to observe (i) photoeffects for redox reagents spanning a range of <*>‘s that is greater than the direct Eg and (ii) constant photovoltage for a range of <*>‘s evidences an important role for surface states or carrier inversion such that a constant amount of band bending (constant barrier height) is found for a couple having <*> more positive than ca. +0.7 V vs.SCE.Conversion of <*> light to electricity can be sustained in CH3CN solutions of Xn-/X- (X = Cl, Br, I) with an efficiency that is ordered Cl > Br > I where n-type MoSe2 is used as a stable photoanode.In aqueous solution n-type MoSe2 is not a stable anode in the presence of similar concentrations of Br2/Br- or Cl2/Cl-, showing an important role for solvent in thermodynamics for electrode decomposition.In CH3CN, efficiency for conversion of 632.8-nm light to electricity has been found to be up to 7.5percent for Cl2/Cl-, 1.4percent for Br2/Br-, and 0.14percent for I3-/I-.Differences among these redox systems are output voltage and short-circuit current, accounting for the changes in efficiency.In H2O, I3-/I- yields a stable n-type MoSe2-based photoelectrochemical cell with an efficiency for 632.8-nm light a little lower that for the CH3CN/Cl2/Cl- solvent/redox couple system.Data for MoS2-based cells in the CH3CN/Xn-/X- solvent/redox couple systems show that the efficiency again depends on X: Cl > Br >I. …

The electrochemical properties of Ti20Mo alloys prepared using different fabrication procedures, namely cold crucible levitation melting (CCLM) and powder sintering, were investigated using linear potentiodynamic polarization and EIS measurements. The surface condition was established using AFM, with the observation of a more porous surface finish in the case of powder sintering. A major effect of surface conditioning on the corrosion resistance of Ti20Mo alloys was observed, where the compact finish exhibits a superior corrosion resistance in chloride-containing saline solutions. Less insulating surfaces towards electron exchange resulted for the more porous finish as revealed by scanning electrochemical microscopy (SECM).

Horse-chestnut ethanolic extract was tested as potential corrosion inhibitor of bronze in simulated acid rain. The extract was analysed by FTIR, GC?MS and HPLC-PDA, and its anti-corrosion behaviour studied using a multiscale electrochemical approach by polarization curves, EIS and scanning electrochemical microscopy, along with SEM-EDS. 94 % inhibition efficiency was attained by developing a surface physisorbed film. A novel methodology for kinetic evaluation of dynamic adsorption of inhibitive species on metal surface is proposed using SECM, achieving good agreement with results from conventional electrochemical techniques. Excellent adsorption-desorption kinetic constants (ka = 0.102 s?1 mol?1 L; kd = 3.33 × 10-5 s?1) were determined.
