A dual-stream flow injection method has been developed for electrochemical detection of ferrocene derivatives in flow streams. The method is based on a previously described electrochemical amplification method in which currents for analyte oxidation are enhanced by rapid analyte regeneration via a solution-phase electron exchange reaction with a sacrificial reagent. The use of two independent flow channels in the present method, one to carry the analyte and another to supply the sacrificial reagent, eliminates the necessity of spiking samples and calibration standards with sacrificial reagent to avoid injection transients. Hydrodynamic voltammograms were recorded for a series of injections of hydroxymethylferrocene (HMFc, a model ferrocene analyte) into the carrier stream in the presence and absence of ferrocyanide (which serves as sacrificial reagent) in the reagent stream. From these voltammograms an optimum detection potential for HMFc of +0.8 V versus Ag|AgCl|KClsat was selected. Two different concentrations of sacrificial reagent were tested for a range of HMFc concentrations between 1 × 10-3 and 1 × 10-8 M for which both unamplified and amplified peaks could be detected. An amplification factor of approximately 300 was obtained for a 1 × 10-8 M HMFc injection with 2 × 10-4 M ferrocyanide present in the reagent stream.

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. Recommanded Product: 1271-51-8. Catalysts allow a reaction to proceed via a pathway that has a lower activation energy than the uncatalyzed reaction. Introducing a new discovery about 1271-51-8, Name is Vinylferrocene

X-ray absorption spectroscopy (XAS) was used to study the electrochemical incorporation of perrhenate anion, from a 0.1 M NH4ReO4 solution, into poly(vinylferrocene) (PVFc) and a modified PVFc (a copolymer of 30% t-butyl acetylferrocene and 70% t-butyl divinyl ferrocene). The polymers were deposited on a carbon cloth current collector from a solution of the polymers in CH2Cl2. In situ XAS measurements were done at the Fe K edge on the reduced polymers and at 0.9 V vs. Ag/AgCl. Ex situ XAS was done at the Re L3 edge after oxidation of the polymers at 0.9 V. The oxidized electrodes were washed in water to remove dissolved NH4ReO4 in the electrode pores. XAS was done both on wet-washed electrodes and on electrodes that were dried. XAS showed that at 0.9 V the Fe was oxidized from a ferrocene to a ferrocenium moiety and the Fe-C bond distance increased from 2.05 to 2.08 A. Both the X-ray absorption near-edge spectroscopy and extended X-ray absorption fine structure (EXAFS) results are consistent with having >75% of the ferrocene moieties in the polymer oxidized at 0.9 V. The Fe K-edge EXAFS showed no direct indication of interaction of Fe with ReO4-. At the Re L3 edge the only indication of interaction of ReO4- with the polymers was a slight change in the XANES features.

Chemistry is a science major with cience and engineering. The main research directions are preparation and modification of special coatings, and research on the structure and performance of functional materials. In a patent, 1271-48-3, name is 1,1′-Ferrocenedicarboxaldehyde, introducing its new discovery. Application In Synthesis of 1,1′-Ferrocenedicarboxaldehyde

The bitopic ligand 1,1?-bis(dipyrazol-1-ylmethyl)ferrocene, Fe[C 5H4CH(pz)2]2 (1; pz = pyrazolyl ring), has been prepared by the reaction of 1,1?-ferrocenedicarbaldehyde and 1,1?-carbonyldipyrazole. In the solid state, the bis(pyrazolyl) methane moieties are in an antiperiplanar eclipsed orientation. The molecules are organized into a three-dimensional array by pi…pi, weak C-H-…N hydrogen bonding, and C-H…pi interactions. The reactions between 1 and AgBF4, AgPF6, AgSO3CF 3, or AgSbF6 yield {Fe[C5H 4CH(pz)2]2AgBF4}n (2), {Fe[C5H4CH(pz)2]2AgPF 6}n (3), {Fe[C5H4CH(Pz) 2]2AgSO3CF3}n (4), and {Fe[C5H4CH(pz2]2AgSbF 6}n (5), respectively. The solid-state structures consist of coordination polymers with compounds 2 and 3 arranged in helical chains, while the chains in 3·1/2Et2O, 4·1.5C6H 6,5·1/2Et2Et2O, and 5·1/2C 6H6 are nonhelical. In these structures, the ferrocenyl groups adopt a similar orientation, where the angle between CH(pz)2 groups is confined to the range of 85-99 and the silver pyrazolyl coordination spheres are also in very similar distorted-tetrahedral arrangements. Both structural types form three-dimensional supramolecular structures organized by weak hydrogen bonds, pi…pi stacking, and CH…pi interactions. In the helical form, the anions reside in the pockets formed by the close-packed chains, whereas in the nonhelical form, sizable channels, which contain the solvent molecules and the anions, are located between the chains.

Organometallic Ru(II)-cymene complexes linked to ferrocene (Fc) via nitrogen heterocycles have been synthesized and studied as cytotoxic agents. These compounds are analogues of Ru(II)-arene piano-stool anticancer complexes such as RAPTA-C. The Ru center was coordinated by pyridine, imidazole, and piperidine with 0-, 1-, or 2-carbon bridges to Fc to give six bimetallic, dinuclear compounds, and the properties of these complexes were compared with their non-Fc-functionalized parent compounds. Crystal structures for five of the compounds, their Ru-cymene parent compounds, and an unusual trinuclear compound were determined. Cyclic voltammetry was used to determine the formal MIII/II potentials of each metal center of the Ru-cymene-Fc complexes, with distinct one-electron waves observed in each case. The Fc-functionalized complexes were found to exhibit good cytotoxicity against HT29 human colon adenocarcinoma cells, whereas the parent compounds were inactive. Similarly, antibacterial activity from the Ru-cymene-Fc compounds was observed against Bacillus subtilis, but not from the unfunctionalized complexes. In both cases, the IC50 values correlated quantitatively with the Fc+/0 reduction potentials. This is consistent with more facile oxidation to give ferrocenium, and subsequent generation of toxic reactive oxygen species, leading to greater cytotoxicity. The antioxidant properties of the complexes were quantified by a 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging assay. EC50 values indicate that linking of the Ru and Fc centers promotes antioxidant activity.

A sustainable and green route to access diverse functionalized ketones via dehydrogenative?dehydrative cross-coupling of primary and secondary alcohols is demonstrated. This borrowing hydrogen approach employing a pincer N-heterocyclic carbene Mn complex displays high activity and selectivity. A variety of primary and secondary alcohols are well tolerant and result in satisfactory isolated yields. Mechanistic studies suggest that this reaction proceeds via a direct outer-sphere mechanism and the dehydrogenation of the secondary alcohol substrates plays a vital role in the rate-limiting step.

MicroRNAs (MiRNAs) have been regarded as clinically important biomarkers and drug discovery targets. In this work, we reported a simple and ultrasensitive electrochemical method for miRNAs detection based on single enzyme amplification and electrochemical-chemical-chemical (ECC) redox cycling. Specifically, upon contact with the target miRNAs, the hairpin structure of biotinylated DNA immobilized on gold electrode was destroyed and the biotin group in DNA was forced away from the electrode surface, allowing for the coupling of streptavidin-conjugated alkaline phosphatase (SA-ALP). Then, ascorbic acid (AA, the enzymatic product of ALP) triggered the ECC redox cycling with ferrocene methanol (FcM) and tris(2-carboxyethyl)phosphine (TCEP) as the redox mediator and the chemical reducing reagent, respectively. The method was more sensitive than that with horseradish peroxidase (HRP) or glucose oxidase (GOx) triggered recycling since one ALP molecule captured by one target miRNA molecule promoted the production of thousands of AA. Analytical merits (e.g., detection limit, dynamic range, specificity, regeneration and reproducibility) were evaluated. The feasibility of the method for analysis of miRNA-21 in human serum has also been demonstrated.

Soluble amyloid-beta oligomer (AbetaO) is believed to be a reliable molecular biomarker for the diagnosis of Alzheimer’s disease (AD) because of its high toxicity for neuronal synapse and higher concentration level in cerebrospinal fluid sample from AD patient than from control individual. At present, it is critical to develop a simple method for AbetaO detection with low cost as well as high sensitivity and selectivity. In this work, we reported an antibody-free electrochemical method for the detection of AbetaO based on the specific interaction between AbetaO and PrP(95-110) peptide, a segment of cellular prion protein. Specifically, cysteine-containing PrP(95-110) peptide was first immobilized on a gold electrode for the capture of AbetaO. Then, alkaline phosphatase-conjugated PrP(95-110) was used for the recognition of the captured AbetaO and the generation of electroactive species. Furthermore, an “outer-sphere to inner-sphere” electrochemical-chemical-chemical (ECC) redox cycling using ferrocene methanol as the redox mediator was employed to enhance the detection sensitivity. As a result, a detection limit of 3 pM for equivalent monomer was achieved. The amenability of this method to AbetaO analysis in a biological matrix was demonstrated by assays of AbetaO in serum samples.
