In heterogeneous catalysis, catalysts provide a surface to which reactants bind in a process of adsorption. Introducing a new discovery about 1293-65-8, Name is 1,1′-Dibromoferrocene

A novel polar dppf derivative possessing only planar chirality, 1?,2-bis(diphenylphosphino)-ferrocene-1-carboxylic acid (Hdpc), has been synthesised in racemic form and resolved into enantiomers via esters with d-glucose diacetonide ((Rp)- and (Sp)-3). (R p)-Hdpc was further converted to a series of N-substituted amides that were studied as ligands for Pd-catalysed enantioselective allylic alkylation of racemic (E)-1,3-diphenylprop-2-en-1-yl acetate or ethyl carbonate with malonate esters, showing high activity and good enantioselectivity (er up to 10: 90). The catalytic results were correlated with the structural data (X-ray diffraction and solution NMR) for (eta3-allyl)palladium(ii) complex (Rp)-[Pd(eta3-1,3-Ph2C 3H3){Fe(eta5-C5H 3-1-(C(O)NHCH2Ph)-2-(PPh2-kappaP)) (eta5-C5H4PPh2-kappaP)}]ClO 4 (16) as a model of the plausible reaction intermediate. A further study into the coordination properties of Hdpc led to isolation of chelate complex [PdCl2(Hdpc-kappa2P,P?)] (12). The crystal structures of rac-Hdpc, methyl ester of (Rp)-Hdpc, glycoside (R p)-3, and 12·Me2CO suggested a close structural relationship between dppf and Hdpc.

Reference of 16009-13-5, Enzymes are biological catalysts that produce large increases in reaction rates and tend to be specific for certain reactants and products. 16009-13-5, Name is Hemin, molecular weight is 651.94. In an Article，once mentioned of 16009-13-5

Resonance Raman spectra of beta-hematin and hemin are reported for a range of excitation wavelengths including 406, 488, 514, 568, 633, 780, 830, and 1064 nm. Dramatic enhancement of A1g modes (1570, 1371, 795, 677, and 344 cm-1), ring breathing modes (850-650 cm-1), and out-of-plane modes including iron-ligand modes (400-200 cm-1) were observed when irradiating with 780- and 830-nm laser excitation wavelengths for beta-hematin and to a lesser extent hemin. Absorbance spectra recorded during the transformation of hemin to beta-hematin showed a red-shift of the Soret and Q (0-1) bands, which has been interpreted as excitonic coupling resulting from porphyrin aggregation. A small broad electronic transition observed at 867 nm was assigned to a z-polarized charge-transfer transition dxy ? eg(pi*). The extraordinary band enhancement observed when exciting with near-infrared excitation wavelengths in beta-hematin when compared to hemin is explained in terms of an aggregated enhanced Raman scattering hypothesis based on the intermolecular excitonic interactions between porphyrinic units. This study provides new insight into the electronic structure of beta-hematin and therefore hemozoin (malaria pigment). The results have important implications in the design and testing of new anti-malaria drugs that specifically interfere with hemozoin formation.

Scanning electrochemical microscopy in feedback mode was used to monitor changes in the surface state of a polymeric film applied on a metallic substrate when exposed to an aqueous electrolytic environment. The protected metal consisted of a carbon steel substrate coated with a polyurethane-based polymeric film. SECM measurements performed in the presence and absence of chloride anions permitted a specific effect caused by Cl- anions at early exposures to be detected. Significant surface roughening is observed for immersion times shorter than 1 day when the electrolyte contains chloride ions. Additionally, the growth of an individual blister could also be investigated.

New protocols for controlled reduction of carboxamides to either alcohols or amines were established using a combination of sodium hydride (NaH) and zinc halides (ZnX2). Use of a different halide on ZnX2 dictates the selectivity, wherein the NaH-ZnI2 system delivers alcohols and NaH-ZnCl2 gives amines. Extensive mechanistic studies by experimental and theoretical approaches imply that polymeric zinc hydride (ZnH2)? is responsible for alcohol formation, whereas dimeric zinc chloride hydride (H?Zn?Cl)2 is the key species for the production of amines.

Pyranose oxidase (POx) catalyzes the oxidation of D-glucose to 2-ketoglucose with concurrent reduction of oxygen to H2O2. POx from Trametes ochracea (ToPOx) is known to react with alternative electron acceptors including 1,4-benzoquinone (1,4-BQ), 2,6-dichlorophenol indophenol (DCPIP), and the ferrocenium ion. In this study, enzyme variants with improved electron acceptor turnover and reduced oxygen turnover were characterized as potential anode biocatalysts. Pre-steady-state kinetics of the oxidative half-reaction of ToPOx variants T166R, Q448H, L545C, and L547R with these alternative electron acceptors were evaluated using stopped-flow spectrophotometry. Higher kinetic constants were observed as compared to the wild-type ToPOx for some of the variants. Subsequently, the variants were immobilized on glassy carbon electrodes. Cyclic voltammetry measurements were performed to measure the electrochemical responses of these variants with glucose as substrate in the presence of 1,4-BQ, DCPIP, or ferrocene methanol as redox mediators. High catalytic efficiencies (Imax app/KM app) compared to the wild-type POx proved the potential of these variants for future bioelectrocatalytic applications, in biosensors or biofuel cells. Among the variants, L545C showed the most desirable properties as determined kinetically and electrochemically.

A carbon nanotube (CNT)-modified electrode was fabricated by dropping a dispersion of multi-walled CNTs in water-soluble and amphiphilic phospholipid polymer with both dispersing ability and anti-biofouling property onto a Au electrode. A poly(2-methacryloyloxyethyl phosphorylcholine-co-n-butyl methacrylate) (PMB) composed from 50 mol% of 2-methacryloxylethyl phosphorylcholine and 50 mol% of n-butyl methacrylate (PMB50) was used as dispersing reagent for CNTs. The dispersion of water-insoluble material by PMB50 and its antifouling effects in electrochemical analysis were investigated. The CNT-modified electrode showed an anodic peak potential that was shifted negatively and an increase in the current value for the electrolytic oxidation of nicotinamide adenine dinucleotide. In addition, the charge on PMB50 did not inhibit the electrochemical reaction of the redox compounds K3[Fe(CN)6], [Ru(NH3)6]Cl3, and hydroxymethylferrocene. Cyclic voltammetry of K3[Fe(CN)6] in 4 % bovine serum albumin (BSA) using a bare Au electrode, the anodic peak current was reduced to 47 % of that without BSA. In contrast, the antifouling effect of the PMB50-coated electrode meant that the current was only reduced to 70 % of that without BSA.

The inhibitive effects of alternating current-treated (AC-treated) mixed self-assembled monolayer (SAMHL/DT) with 2-(Pyridin-2-yliminomethyl)-phenol (HL) and dodecanethiol (DT) on copper corrosion have been studied by using the scanning electrochemical microscope (SECM) combined with Tafel and electrochemical impedance spectroscopy (EIS) methods When the AC-treated potential is applied in the cathodic region, the inhibition efficiency increases, and the pitting dynamic processes are inhibited. All the results reveal that the AC-treated effects are related to both the formation of complex compounds and the reduction of the oxide film on the surface of copper.
