Highly efficient reduction of ferrocenyl derivatives by borane

Borane, as a DMS or a THF complex, can efficiently reduce a large range of ferrocenyl derivatives (aldehydes, ketones, ethers, acetals, carboxylic acids, esters,…) if they bear at least one oxygen at a carbon at the alpha position. On the contrary, similar molecules, which contain nitrogen instead of oxygen, do not react with borane.

Simultaneous Multiplex Potentiostatic Electroanalysis with Liquid-Junction-Removed Reference Electrode System using a Closed Bipolar Electrode

A novel liquid-junction-removed reference electrode system was developed for simultaneous multiplex amperometry using a closed bipolar electrode. The liquid junction between the reference cell and the sample cell was replaced by a bipolar electrode to ensure electron conductivity in lieu of ionic conductivity in conventional systems. Under the condition where the redox reaction of the analyte at the bipolar electrode in the sample cell was a limiting process, voltammetric and amperometric measurements were performed for quantitative detection of the analytes. After characterization of the system, a chip-type device was fabricated with six sample cells and one reference cell. Simultaneous determination of ferrocene methanol was conducted in six solutions in the 0.1?0.5 mM range. This is the first demonstration of the simultaneous multiplex determination of analytes with a liquid-junction-removed system. Although the potential control problem (which is different to the liquid potential problem of conventional liquid junction) still remains because of the increase of the solid?liquid interface, this system is expected to solve some problems associated with the liquid junction of the reference electrode, including sample contamination by chloride ions and the complicated process of fabricating a reference electrode on a chip.

Homochiral arsenic-/phosphorus-based ligands

The synthesis of homochiral phosphorus-based ligands has escalated dramatically over the last decade in the drive to develop new, and further fine tune existing, base structures of chiral auxiliaries that have had, and most certainly are continuing to have, a phenomenal impact in the arena of enantioselective catalysis. This review highlights the vast array of homochiral phosphorus-based ligands and their significantly fewer arsenic-based analogs, the key synthetic strategies used to prepare them and the significant roles that they have been employed in after coordination to a transition metal center.

Carboxylate anions binding and sensing by a novel tetraazamacrocycle containing ferrocene as receptort

A tetraazamacrocycle containing ferrocene moieties has been synthesized and characterized. The tetraprotonated form of this compound was evaluated as a receptor (R) for anion recognition of several substrates (S), Cl-, PF6-, HSO4-, H2PO 4- and carboxylates, such as p-nitrobenzoate (p-nbz -), phthalate (ph2-), isophthalate (iph2-) and dipicolinate (dipic2-). 1H NMR titrations in CD 3OD indicated that this receptor is not suitable for recognizing HSO4- and H2PO4-, but weakly binds p-nbz-, and strongly interacts with ph2-, dipic2-, and iph2- anions forming 1 : 2 assembled species. The largest beta2 binding constant was determined for ph 2-, followed by dipic2- and finally iph2-. The effect of the anionic substrates on the electron-transfer process of the ferrocene units of R was evaluated using cyclic voltammetry (CV) and square wave voltammetry (SWV) in methanol solution and 0.1 mol dm-3 (CH 3)4NCl as the supporting electrolyte. Titrations of the receptor were undertaken by addition of anion solutions in their tetrabutylammonium or tetramethylammonium forms. The protonated ligand exhibits a reversible voltammogram, which shifts cathodically in the presence of the substrates. The data revealed kinetic constraints in the formation of the receptor/substrate entity for dipic2-, ph2- and iph 2- anions, but not for p-nbz-. In spite of the slow kinetics of assembled species formation with the ph2- substrate, this anion provides the largest redox-response when the supramolecular entity is formed, followed by dipic2-, iph2- and finally p-nbz – anions. This trend is in agreement with the 1H NMR results and the values of the binding constants. Single crystal X-ray structures of the receptor with PF6-, ph2-, iph 2- and p-nbz- were carried out and showed that supermolecules with a RS2 stoichiometry are formed with the first three anions, but RS4 with p-nbz-. In all cases the binding occurs outside the macrocyclic cavity via N-H … O=C hydrogen bonds for carboxylate anions and N-H … F hydrogen bonds for the PF 6- anion, which is in agreement with the solution results. The macrocyclic framework adopts different conformations in order to interact with each substrate having Fe … Fe intramolecular distances ranging from 10.125(14) to 12.783(15) A.

The stability of diazonium ion terminated films on glassy carbon and gold electrodes

Glassy carbon (GC) and Au electrodes were modified with aminophenyl films by electroreduction of the corresponding diazonium salt. Aminophenyl films were diazotised using both aqueous and non-aqueous conditions, to generate film-based phenyldiazonium ions. The stabilities of the diazonium terminated films, to exposure to air and in acidic solution, were investigated by cyclic voltammetry (CV). For films of the same thickness, those grafted to Au substrates are more stable than those grafted to GC.

3D-printed photo-spectroelectrochemical devices for in situ and in operando X-ray absorption spectroscopy investigation

Three-dimensional printed multi-purpose electrochemical devices for X-ray absorption spectroscopy are presented in this paper. The aim of this work is to show how three-dimensional printing can be a strategy for the creation of electrochemical cells for in situ and in operando experiments by means of synchrotron radiation. As a case study, the description of two cells which have been employed in experiments on photoanodes for photoelectrochemical water splitting are presented. The main advantages of these electrochemical devices are associated with their compactness and with the precision of the three-dimensional printing systems which allows details to be obtained that would otherwise be difficult. Thanks to these systems it was possible to combine synchrotron-based methods with complementary techniques in order to study the mechanism of the photoelectrocatalytic process.

Soap film electrochemistry

In this paper we present preliminary electrochemical investigations into the transport properties of free standing ultra-thin surfactant films and the associated meniscus. We describe a new electrochemical cell composed of a 25 mum diameter gold wire placed through a stable surfactant film which served as the electrolyte. Solutions containing anionic sodium dodecyl sulphate (SDS) or non-ionic Triton-X100 surfactants, with background electrolyte NaCl and with electroactive probe ferrocyanide or ferrocene methanol, were used to create the surfactant films. The electrolyte was an ultra-thin surfactant film creating a two dimensional solution with a thickness between 300 and 1000 nm, and its meniscus at the gold wire, within which the electroactive probe was free to diffuse. Cyclic voltammetry was used to oxidise and reduce the electroactive probe within the surfactant film and meniscus. It was shown that films and the associated meniscus formed from SDS solution almost completely excluded negatively charged ferrocyanide. A finite difference simulation showed that the voltammetry was dominated by the meniscus region, the unusual spatially-varying bounded geometry of which resulted in an unusual dependence on potential scan rate of the peak to peak separation (decreasing with increasing scan rate) and anodic:cathodic peak current ratio (increasing with increasing scan rate).

Synthesis of new ferrocenyl derivatives and their use in the first cyclopropanation of fullerene C60 with ferrocenes

New ferrocenyl derivatives (a beta-ketoester and a beta-diester) were synthesised and linked to fullerene C60, with the aim to elucidate factors involved in intramolecular electronic communication. These are the first examples of fullerene functionalised with ferrocenes via the cyclopropanation reaction. The resulting dyads were characterised.
