“…A pair of reversible redox peaks could be observed on Fca-RTIL-CA-SPGE electrode. The anodic and cathodic peak potentials were located at 0.371 and 0.309 V, respectively and the peak separation (ΔE p ) was found to be ~62 mV; which is considerably close to 59 mV value expected for Nernstian one electron reactions [20]. However, very weak peaks (not shown) could be observed when Fca-CA-SPGE, Fca-RTIL-SPGE and Fca-SPGE electrodes were used immediately following fabrication and no redox peaks were observed after overnight storage in buffer solution.…”

Globally, the use of H 2 O 2 for the preservation of raw milk has a long established history. However, in the EU, US and most parts of the world, where access to refrigeration facilities is widely available, the adulteration of milk with H 2 O 2 is generally not permitted. An inhouse hand-printed carbon electrode consisting of graphite printing ink modified with the room temperature ionic liquid (RTIL), 1-ethyl-3-methylimidazolium tetrafluoroborate ([EMIM][BF 4 ]), ferrocene carboxylic acid (Fca) and cellulose acetate (CA) for the electrochemical sensing of hydrogen peroxide (H 2 O 2) in commercially packaged aseptic milk is described. The developed electrode successfully enabled sensitive determination of H 2 O 2 , free from interference from some known electroactive species such as ascorbic acid (AA), dopamine (DA), glucose and uric acid (UA). The linear range for the determination of H 2 O 2 was 1.0 μM-1.2 mM with a limit of detection of 0.35 μM and a sensitivity of 10.6 nAμA-1 μM-1 cm-2. When used for the analysis of H 2 O 2 residues in milk samples, the resulting precision (n = 6) and recovery were 0.53 % and 97.8 %, respectively.

“…[3a,d] The quasi-reversible wave could be ascribed to the reduction of 2 a, as a similar E 1/2 (À1.50 V) was determined for the anionic/neutral couple of stannaferrocene. [4h] This potential is much less negative than that for Fc/Fc À (À3.446 V vs. Fc + /Fc), [25] suggesting that 2 a is easier to be reduced than ferrocene.…”

Dinickelaferrocene: A Ferrocene Analogue with Two Aromatic Nickeloles Realized by Electron Back‐Donation from Iron

et al. 2020

The first example of ferrocene analogues with two transition‐metal metallole ligands of the general formula (η5‐C4R4M)2Fe in a sandwich structure are reported. Specifically, dinickelaferrocene 2, a type of dimetallametallocene, is efficiently synthesized from the reaction of dilithionickelole 1 with FeBr2 or FeCl2, presumably via a redox process, and is subjected to detailed experimental (single‐crystal X‐ray structural analysis, ICP‐OES, magnetometry, 57Fe Mössbauer, XPS) and theoretical (MOs, CDA, NICS, ICSS, and AICD) characterizations. Unlike ferrocene and its Cp ligands, the aromaticity of dinickelaferrocene and its nickelole ligands is accomplished by electron back‐donation from the Fe 3d orbitals to the π* orbitals of nickelole. Taken together, this work describes a new class of metallaferrocene sandwich complexes and provides a novel approach to effect aromaticity that will contribute to further development of metallocene chemistry.

“…In the case of organic solvents, redox species such as ferrocene (Fe(C 5 H 5 ) 2 , Fc), anthracene (C 14 H 10 , An), and hydroquinone (C 6 H 4 (OH) 2 ) are often used. Unlike aqueous solutions, the solubility and conductivity of certain solutes depend on the nature of the organic solvents, therefore the selection of electrolytes and redox materials replies on the organic solvents used . Until now, the electrochemical studies have been investigated in various solvents including: ethanol, propylene carbonate, dimethylformamide, methanol, nitrobenzene, tetrahydrofuran, pyridine, benzonitrile, dimethylsulfoxide, acetone, and most commonly, acetonitrile .…”

In this study, electrochemical experiments were carried out in chloroform using ferrocene (Fc) or anthracene (An). We performed cyclic voltammetry (CV) on Fc and An in chloroform containing either tetrabutylammonium perchlorate (TBAP) or tetrabutylammonium hexafluoro‐phosphate (TBAPF6 ) over the temperature range of 25 to 50°C. The resulting pattern of CVs, half‐wave potential ( E 1 /2), diffusion coefficient of Fc and An, steady‐state current, solution viscosity, and long‐term stabilities were studied.
