Unscrambling illusory inhibition and catalysis in nanoparticle electrochemistry: Experiment and theory

Recent theoretical work (Applied Materials Today 15 (2019), pp. 139-144)has demonstrated that the cyclic voltammetry of particle-modified electrodes bears a significant level of complexity: Altered mass transport inside the porous layer gives rise to effects that may falsely suggest positive or negative catalysis. This communication reports experimental work that validates this theory. Using the well-studied oxidation of ferrocenemethanol at glassy carbon, we describe experiments in the presence of non-conducting electrochemically-inert microspheres that reproduce trends in the theoretical predictions and illustrate how experimental results may mislead. In addition, we present experimental data of the reduction of oxygen at glassy carbon electrodes modified with Nafion microspheres and show that, unless compared with theoretical work, an electrocatalytic activity of Nafion may falsely be inferred.

Intermolecular aminocarbonylation of alkenes using concerted cycloadditions of iminoisocyanates

The aminocarbonylation of alkenes is a powerful method for accessing the beta-amino carbonyl motif that remains underdeveloped. Herein, the development of intermolecular aminocarbonylation reactivity of iminoisocyanates with alkenes is presented. This includes the discovery of a fluorenone-derived reagent, which was effective for many alkene classes and facilitated derivatization. Electron-rich substrates were most reactive, and this indicated that the LUMO of the iminoisocyanate is reacting with the HOMO of the alkene. Computational and experimental results support a concerted asynchronous [3 + 2] cycloaddition involving an iminoisocyanate, which was observed for the first time by FTIR under the reaction conditions. The products of this reaction are complex azomethine imines, which are precursors to valuable beta-amino carbonyl compounds such as beta-amino amides and esters, pyrazolones, and bicyclic pyrazolidinones. A kinetic resolution of the azomethine imines by enantioselective reduction (s = 13.43) allows access to enantioenriched products. Overall, this work provides a new tool to convert alkenes into beta-amino carbonyl compounds.

MoS2 nanosheets for improving analytical performance of lactate biosensors

In this paper, a new 2D lactate electrochemical biosensor was developed. It was based on the incorporation of molybdenum disulfide (MoS2) nanosheets, obtained by an exfoliation method, onto the surface of a glassy carbon (GC) electrode, together with lactate oxidase enzyme (LOx). For the sensor construction, conditions regarding the exfoliation solvent type, as well as both the size and amount of MoS2, were optimized. The biosensor platform (GC/MoS2/LOx) was topographically characterized by atomic force microscopy (AFM) and the charge transfer process occurring at the electrode interface was studied by electrochemical impedance spectroscopy (EIS). The GC/MoS2/LOx biosensor was applied to the determination of lactate in presence of hydroxymethylferrocene (HMF) as a redox mediator. Electrocatalytic effect of the system MoS2/LOx was evaluated by comparing the cyclic voltammetric biosensor response with those obtained for biosensors incorporating only one of the components (MoS2 or LOx) onto the electrode surface. Biosensors containing both components exhibit the best electrocatalytic response. From the calibration curve obtained at +0.30 V, the following analytical parameters were obtained: linear concentration range from 0.056 to 0.77 mM, high sensitivity (6.2 muA mM?1), good detection limit (17 muM) and reproducibility (RSD = 4.7%).

Homogeneous Hydrogenation with a Cobalt/Tetraphosphine Catalyst: A Superior Hydride Donor for Polar Double Bonds and N-Heteroarenes

The development of catalysts based on earth abundant metals in place of noble metals is becoming a central topic of catalysis. We herein report a cobalt/tetraphosphine complex-catalyzed homogeneous hydrogenation of polar unsaturated compounds using an air- and moisture-stable and scalable precatalyst. By activation with potassium hydroxide, this cobalt system shows both high efficiency (up to 24 000 TON and 12 000 h-1 TOF) and excellent chemoselectivities with various aldehydes, ketones, imines, and even N-heteroarenes. The preference for 1,2-reduction over 1,4-reduction makes this method an efficient way to prepare allylic alcohols and amines. Meanwhile, efficient hydrogenation of the challenging N-heteroarenes is also furnished with excellent functional group tolerance. Mechanistic studies and control experiments demonstrated that a CoIH complex functions as a strong hydride donor in the catalytic cycle. Each cobalt intermediate on the catalytic cycle was characterized, and a plausible outer-sphere mechanism was proposed. Noteworthy, external inorganic base plays multiple roles in this reaction and functions in almost every step of the catalytic cycle.

beta-Ferrocenyl-beta-amino alcohols: a new class of central chiral ferrocene derivatives

An efficient procedure for the enantioselective synthesis of beta-ferrocenyl-beta-amino alcohols, a new class of central chiral ferrocene derivatives suitable for the elaboration of auxiliaries and ligands for asymmetric synthesis, is described. Key steps of the method are the catalytic asymmetric dihydroxylation of 1-ferrocenyl alkenes and the regio- and stereoselective azide substitution of the hydroxyl group adjacent to the ferrocene moiety. The stereochemistry of the substitution step has been established by X-ray diffraction analysis of a cyclic derivative. The first catalytic enantioselective synthesis of a beta-ferrocenyl-beta-amino acid derivative is also disclosed.

Characterization of home-made graphite/PDMS microband electrodes for amperometric detection in an original reusable glass-NOA-PDMS electrophoretic microdevice

A new dismountable and reusable microchip for electrophoretic separation coupled to amperometric detection was developed. For this purpose, a new home made three-microbands electrode system was developed and microfabricated based on screen-printing for the inclusion of graphite/polydimethylsiloxane (C-PDMS) composite in microchannels down to 30 mum width. The composition of the composite as well as the fabrication methodology were optimized for an easy handling and an optimized electrochemical behavior. The electrochemical characterization of this composite material was first performed in bulk format (disc-shaped electrode, 6 mm diameter). It was then transposed to the micrometric scale for its integration in an original glass-NOA81-PDMS microfluidic device allowing for reversible sealing. The microband electrodes were characterized by scanning electron microcopy and cyclic voltammetry, illustrating a good control of the microelectrode width. Then, the analytical performances of the C-PDMS composite microelectrodes were evaluated using Ru(NH3)6 3+ and FcMeOH as model electroactive molecules. The electrophoretic separation and quantitation of Ru(NH3)6 3+ were then performed in a background electrolyte made of hydrochloric acid and sodium chloride, leading to a LOD and a LOQ of 3.4 mumol L?1 and 11.3 mumol L?1, respectively. The re-openable NOA-based microdevice permits to regenerate the electrode surface by simply repositioning the microband on a new spot, allowing for robust analysis in a reusable system.
