Metal complexes of biologically important ligands. CLXVI [1] metal complexes with ferrocenylmethylcysteinate and 1,1?-ferrocenylbis- (methylcysteinate) as ligands

A series of complexes of transition metal ions (Cr3+, Mn 2+, Co2+, Ni2+, Cu2+, Zn 2+) and of lanthanide ions (La3+, Nd3+, Gd 3+, Dy3+, Lu3+) with the anions of ferrocenylmethyl-L-cysteine [(C5H5)Fe(C5H 4CH(R)SCH2CH(NH3+)CO 2-] (L1) and with the dianions of 1,1?-ferrocenylbis(methyl-L-cysteine) [Fe(C5H 4CH(R)SCH2CH(NH3+) CO 2-)2] (R = H, Me, Ph) (L2) as N,O,S-donors were prepared. With the monocysteine ferrocene derivative L 1 as ligands complexes [MIIL12] or [CrIIIL12]Cl type complexes are formed whereas the bis(cysteine) ligand L2 yields insoluble complexes of type [ML2]n, presumably as coordination polymers. The magnetic moments of [MnIIL2]n, [PrIIIL 2]n(OH)n and [DyIIIL 2]n(OH)n exhibit “normal” paramagnetism.

Polymer network formation using the phosphane-ene reaction: A thiol-ene analogue with diverse postpolymerization chemistry

Air-stable primary phosphines were photopolymerized using phosphane-ene chemistry, the phosphorus analogue of the thiol-ene reaction, to fabricate a completely new class of polymer networks. It was demonstrated that the tunable thermal and physical properties accessible using thiol-ene chemistry could also be achieved using an analogous phosphane-ene reaction. At the same time, the presence of the 31P nucleus that is easily observed using NMR spectroscopy allowed the chemical structures of the networks to be directly probed using solid state NMR spectroscopy. Following its incorporation into the network, phosphorus offers the distinct difference and advantage of being able to undergo a diverse array of further derivatization to afford functional materials. For example, the networks were demonstrated to serve as effective oxygen scavengers and to bind transition metals (e.g., Pd). By using the air stable ferrocenyl phosphine (FcCH2CH2)PH2, redox-active networks were produced and these materials could be pyrolyzed to yield magnetic ceramics. Overall, this demonstrates the promise of phosphane-ene chemistry as an alternative to thiol-ene systems for providing functional materials for a diverse range of applications.

Nylon nanofibrous membrane for mediated glucose biosensing

This work illustrates how polyamide nanofibrous membranes, prepared by the electrospinning process, can act as a new type of biosensor element. The sensing unit is based on a glassy carbon electrode coated with polyamide nanofibrous membranes, in which glucose oxidase is covalently tethered. The work is carried out by means of transient electrochemical techniques, such as cyclic voltammetry and amperometry, in which ferrocene methanol was employed as mediator. The results show that nanofibrous membranes are an excellent support for the development of biosensors thanks to their high-surface to volume ratio, high porosity and permeability of the cosubstrate and minimal effect on both the biocatalytic kinetics and the selectivity of the biorecognition event. The optimization, characterization, and attractive performance of the nanofibrous biosensor are reported in connection with the detection of glucose in a variety of food beverages.

Use of a Cyclometalated Iridium(III) Complex Containing a N?C?N-Coordinating Terdentate Ligand as a Catalyst for the alpha-Alkylation of Ketones and N-Alkylation of Amines with Alcohols

A cyclometalated iridium(III) complex containing a N?C?N-coordinating terdentate ligand [Ir(dpyx-N,C,N)Cl(mu-Cl)]2 was found to be a general and highly effective catalyst for the alpha-alkylation of ketones and N-alkylation of amines with alcohols. In the presence of catalyst (1 mol % Ir) and base (0.2-0.5 equiv), a variety of desirable products were obtained in good yields under an air atmosphere. Notably, this research exhibited the new potential of Ir(III) complexes bearing non-Cp? ligand and will facilitate the progress of the hydrogen autotransfer process.

Unidirectional Current Flow and Charge State Trapping at Redox Polymer Interfaces on Bilayer Electrodes: Principles, Experimental Demonstration, and Theory

Bilayer electrodes consist of conductive electrodes coated with or bonded to two physically discrete polymeric layers which contain two different redox substances having different E0′ values.The redox substance in the inner polymeric film next to the electrode can be oxidized or reduced by the electrode.That in the outer polymer film is constrained, by physical isolation from the electrode, to undergo oxidation or reduction only at electron energies for redox conductivity by the inner film.This arrangement leads to rectified (unidirectional) current flow.Experimental results from bilayer electrodes based on nine different combinations of redox substances in the films are presented to demonstrate the generality of the phenomenon and the ability to fabricate bilayer film.The redox substances include fixed-site redox polymers like poly2+, polyvinylferrocene, poly(4-methyl-4′-vinyl-N,N’-ethylene-2,2′-bipyridinium), and siloxane polymer of N-methyl-N”-(4-(2-(trimethylsilyloxy)ethyl)benzyl)-4-4′-bipyridinium, and (inner film) mobile redox sites like bromide, hexachloroiridate, and benzophenone.Various mechanisms are considered for bilayer electrode nonidealities which appear as a leakage of redox state trapped in the outer film, an a theory describing voltammeric properties of bilayer electrodes is compared to experimental results.

Application of 1271-51-8, Chemistry is the science of change. But why do chemical reactions take place? Why do chemicals react with each other? The answer is in thermodynamics and kinetics.In a document type is Article, and a compound is mentioned, 1271-51-8, Vinylferrocene, introducing its new discovery.

Thermodynamics and kinetics of redox switching of polyvinylferrocene films in perchlorate solutions

Cyclic voltammetry was used to create nonequilibrium populations of different solvation and configurational states of partially oxidized polyvinylferrocene (PVF). Oxidation levels were established by scanning either from a fully reduced state to the desired oxidation level or from a fully oxidized state to the desired level. Coulostatic conditions were then established by opening the external circuit, and subsequent mass and potential changes were followed. The film’s approach to equilibrium involves configurational changes within the polymer and simultaneous and subsequent solvent transfer. At very short times (t a?? 0.2 s) the approach to equilibrium is limited by both solvation and reconfiguration processes. For a short time afterward (0.2 < t/s < 1.0) reconfiguration alone is rate limiting. At intermediate times (1 < t/s < 5) both processes play comparable roles. At long times (r > 5 s) solvation is the controlling step. The electroactive polymer film does not completely reach equilibrium even after 1 h at open circuit as evidenced by continuous small mass changes. These mass changes are the result of water transfer between the polymer film and the bathing electrolyte. A scheme of cubes model rationalizes mechanistic pathways leading to equilibrium. In particular, the observed extrema in mass (solvent population) are predicted. The electrode potential, after 1 h at open circuit, shows nearly Nernstian dependence on the redox composition for film states produced by either anodic or cathodic cyclic voltammetric scans. These Nernst plots are displaced by only a few millivolts because only a weak Nernstian dependence on film water content exists. Films that are 50% oxidized exhibit a sub-Nernstian response with respect to the perchlorate concentration in the bathing solution under permselective conditions.
