Electrocatalytic hydrocarbon hydroxylation by ethylbenzene dehydrogenase from Aromatoleum aromaticum

We report the electrocatalytic activity of ethylbenzene dehydrogenase (EBDH) from the beta-proteobacterium Aromatoleum aromaticum. EBDH is a complex 155 kDa heterotrimeric molybdenum/iron-sulfur/heme protein which catalyzes the enantioselective hydroxylation of nonactivated ethylbenzene to (S)-1-phenylethanol without molecular oxygen as cosubstrate. Furthermore, it oxidizes a wide range of other alkyl-substituted aromatic and heterocyclic compounds to their secondary alcohols. Hydroxymethylferrocenium (FM) is used as an artificial electron acceptor for EBDH in an electrochemically driven catalytic system. Electrocatalytic activity of EBDH is demonstrated with both its native substrate ethylbenzene and the related substrate p-ethylphenol. The catalytic system has been modeled by electrochemical simulation across a range of sweep rates and concentrations of each substrate, which provides new insights into the kinetics of the EBDH catalytic mechanism.

Acceptorless dehydrogenation of alcohols on a diruthenium(II,II) platform

The diruthenium(II,II) complex [Ru2(L1)(OAc)3]Cl (1), spanned by a naphthyridine-diimine ligand and bridged by three acetates, has been synthesized. The catalytic efficacy of complex 1 has been evaluated for the acceptorless dehydrogenation (AD) of alcohols and for the dehydrogenative coupling reactions of alcohols with Wittig reagents. The diruthenium(II,II) complex is an excellent catalyst for AD of a diverse range of alcohols, and it is shown to be particularly effective for the conversion of primary alcohols to the corresponding aldehydes without undesired side products such as esters. Triphenylphosphonium ylides in a one-pot reaction with alcohols afforded the corresponding olefins in high yields with excellent E selectivity. The liberated dihydrogen gas was identified and measured to be 1 equiv with respect to alcohol. Deuteration studies with PhCD2OH revealed the absence of isotope scrambling in the product, indicating the involvement of a Ru-monohydride intermediate. Kinetic studies and DFT calculations suggest a low-energy bimetallic beta-hydride elimination pathway where rate-limiting intramolecular proton transfer from alcohol to metal-bound hydride constitutes the dehydrogenation step. The general utility of metal-metal bonded compounds for alcohol AD and subsequent coupling reactions is demonstrated here.

Photoinduced processes of newly synthesized bisferrocene- and bisfullerene-substituted tetrads with a triphenylamine central block

Photoinduced electron transfer processes of two newly synthesized tetrads with a triphenylamine (TPA) as central building block, to which bisfullerenes (C60) and bisferrocenes (Fc) are covalently connected, have been studied. One of them has a TPA linked with one C60 moiety and two ferrocene moieties C60-TPA-(Fc)2 and another tetrad has a TPA linked with two C60 moieties and one ferrocene unit (C60)2-TPA-Fc. The photophysical properties of (C60)m-TPA-(Fc)n have been investigated by applying the picosecond time-resolved fluorescence and nanosecond transient absorption techniques in both polar and nonpolar solvents. The charge separation process via the excited singlet state of the C60 moiety of the C60-TPA-(Fc)2 is more efficient than that of the (C60)2-TPA-Fc. It is found that the ratio of Fc-donor to C60-acceptor affects charge separation efficiency via the excited singlet state of the C60 moiety.

Advances in the biosensors for lactate and pyruvate detection for medical applications: A review

This review analyzes electrochemical biosensors for the determination of lactate (lactic acid) and pyruvate (pyruvic acid) concentrations in liquid samples, especially in the blood serum. The biosensor systems for the simultaneous determination of both substances and commercial variants of the biosensors are presented, and the biosensors for medical diagnostics are highlighted. The information concerning the necessity of separate and simultaneous determination of lactate and pyruvate, as well as lactate to pyruvate ratio, is given; the traditional methods for the determination of these substances are briefly described. Lactate dehydrogenase and lactate oxidase are shown to be most commonly used in the biosensors for lactate detection. Pyruvate oxidase and living cells are used in the biosensors for pyruvate detection. Different methods of the enzymes immobilization are presented, as well as strategies for enhancement of the biosensor sensitivity. An additional requirement for practical applications is the biosensor resistance to electroactive interferents, inhibitors, biofouling, and electrode passivation; thus, the variants of solving these problems in the biosensors for lactate and pyruvate detection are analyzed.

Self-assembly of conducting cocrystals: Via iodine?pi(Cp) interactions

Conducting crystals of alternating ferrocene and diiodoacetylene units assembled into supramolecular 1-D chains via I?pi(Cp) halogen bonds were prepared and structurally characterized. Their structure and conductivity were compared with the ferrocene cocrystals with phenyliodoacetylene (C6H5C2I) and 1,4-di(ethynyliodo)phenylene. Electrical conductivity measurements of the ferrocene-based cocrystals revealed comparatively high electron-hole type conductivity in the ferrocene (FcH)-diiodoacetylene (C2I2) pair, a 3-order decrease in combination with the 1,4-di(ethynyliodo)phenylene linker, and it is virtually extinguished with the monotopic 1,2-phenyliodoacetylene. The increased electric conductivity of compound 1 is rationalized in terms of a weak charge transfer through the I?piCp halogen bonds in the [Cp-Fe-Cp?I-CC-I?]n polymeric chains.

Si(OCH2Fc)4: Synthesis, Electrochemical Behavior, and Twin Polymerization

The preparation and twin polymerization of the twin monomer Si(OCH2Fc)4 [Fc = Fe(eta5-C5H4)(eta5-C5H5)] (2) by the reaction of FcCH2OH (1) with SiCl4 in the presence of pyridine was explored. The electronic properties of 2 were investigated by cyclic voltammetry, square-wave voltammetry, and UV/Vis/near-IR spectroelectrochemistry, which showed a redox separation caused by electrostatic repulsion. Thermally induced condensation of 2 is characteristic, as evidenced by differential scanning calorimetry (DSC) and thermogravimetry coupled mass spectrometry (TG-MS). Upon heating 2 to 210 C, twin polymerization occurred and a hybrid material was formed that showed similarities with known systems derived from 2,2?-spirobi[4H-1,3,2-benzodioxasiline] (SBS), such as the nanopatterning of the formed silicon dioxide, which is characteristic for twin polymerization. Electron microscopy of this material revealed the absence of typical microstructuring found for other twin polymers, and hence, the herein presented system can be characterized as a borderline system if compared to known twin monomers such as SBS. The copolymerization of 2 and SBS afforded a hybrid material from which porous carbon or silica materials containing iron oxide nanoparticles could be obtained. The oxidation state of the incorporated particles was examined by Moessbauer experiments, which confirmed that only FeIII was incorporated within the porous carbon and silica materials, respectively. The preparation of iron oxide containing porous carbon capsules was achieved by applying a mixture of 2 and SBS to silicon dioxide spheres (d = 200 nm). After twin polymerization and carbonization, porous carbon capsules with incorporated iron oxide nanostructures were obtained. The straightforward preparation of iron-rich porous carbon and silica materials by twin polymerization of Si(OCH2Fc)4 [Fc = Fe(eta5-C5H4)(eta5-C5H5)] and 2,2?-spirobi[4H-1,3,2-benzodioxasiline] is reported; the electrochemical properties of Si(OCH2Fc)4 are discussed.

Synthesis of controlled pi-extended conjugate nanostructures of 1,1?-ferrocene

Synthesis of the (E,E)-1,1?-ferrocene nanostructures having controlled pi-extended conjugation was satisfactory carried out starting of 1?-[2-(1,3-dioxolan)]-1-formylferrocene (1). The molecular unit (E)-1?-[2-(1,3-dioxolan)]-1-[beta-(p-iodophenyl)ethenyl]ferrocene (2), was obtained in excellent yield by treatment of 1 with p-iodobenzyl triphenylphosphonium ylid followed by Z?E isomerization, catalyzed by iodine, in quantitative yield. Compound (E)-2 was transformed in (E)-1?-{2-(1,3-dioxolan)-1-[beta-[4-(3-hydroxy-3-methyl-but-1-ynyl)-phenyl]-ethenyl}ferrocene, (E)-4, by palladium catalyzed cross-coupling with 2-methyl-but-3-yn-2-ol. (E)-4 gives (E)-1-[beta-(4-ethynylphenyl)-ethenyl]-1?-[2-(1,3-dioxolan)]ferrocene (E)-5 by powder sodium hydroxide treatment. The molecular unit (E,E)-1-{beta-[4-(beta-(1?-formylferrocenyl)-ethenyl)-phenylethynyl]-phenyl]-ethenyl}-1?-formylferrocene, (E,E)-6, was synthesized by palladium catalyzed cross-coupling between the p-iodophenyl derivative (E)-2 and their ethynyl derivative (E)-5, in good yield. The (E,E)-1,1?-(p-iodophenyl)ethenyl ferrocene, (E,E)-7, was synthesized by reaction between 1,1?-diformylferrocene and the p-iodobenzyltriphenylphosphonium ylid, as a mixture of isomers which were purely isolated. Moreover, isomerization of the Z,Z and E,Z mixture to the E,E isomer, was induced by sunlight exposure, catalyzed by iodine, in quantitative yield. The (E,E)-1,1?-[beta-(4-ethynylphenyl)-ethenyl]ferrocene, (E,E)-10, was synthesized in good yield, by palladium catalyzed cross-coupling of compound (E,E)-7 with 2-methyl-but-3-yn-2-ol, followed by powder sodium hydroxide treatment.

Extended Investigation of Electrochemical CO2 Reduction in Ethanolamine Solutions by SECM

The electrochemical reduction of carbon dioxide is very much in the focus of interest today. Intensive research is carried out in leading laboratories trying to work out methods for making useful materials from this unwanted greenhouse gas using solar or wind power generated excess electric energy. In this work, electrochemical reduction experiments are carried out in homemade cells supplied with different metal electrodes. Electrolytes containing carbon dioxide absorbing components like monoethanolamine (MEA) or KHCO3, KOH, and K2CO3 solutions are used. Metal-containing species were noticed in the used electrolytes after being in contact with the metal working electrodes. Therefore parallel to the electrochemical measurements, the metal components in the electrolyte were checked with atomic absorption methods for getting better insight into the nature of the electrode passivation. This paper attempts to compare the behavior of different electrode materials (copper, nickel) in CO2 capturing media, and investigate of the products of the electrolysis using Scanning Electrochemical Microscopy (SECM), Atomic Absorption Spectroscopy (AAS) and gas chromatography.

Recent developments, characteristics and potential applications of screen-printed electrodes in pharmaceutical and biological analysis

Screen-printed electrodes (SPEs) have gone through significant improvements over the past few decades with respect to both their format and their printing materials. Thus, SPEs have been successfully applied for the in situ detection of a plethora of analytes in a wide range of sample matrixes due to their advantageous material properties, such as disposability, simplicity, and rapid responses. In particular, the development of electrochemical sensors based on SPEs for pharmaceutical analysis has received massive consideration since they enable the rapid screening of the pharmaceutical compounds in complex matrixes, requiring small volumes of samples and no pre-treatment steps. This review summarizes the design and the working principles of electrochemical sensors based on SPEs applied to the quantification of pharmaceutical and biological compounds.
