Improved synthesis of diethyl ferrocenylphosphonate, crystal structure of (FcPOFcPO3Et22)2 ¡¤ZnCl 2, and electrochemistry of ferrocenylphosphonates, FcP(O)(OR)2, FcCH2P(O)(OR)2, 1,10?-fc[P(O)(OR)2]2 and [FcP(O)(OEt) 2]2 ¡¤ZnCl2

An improved synthesis of diethyl ferrocenylphosphonate using the tBuLi/tBuOK system at low temperature is reported and the structure of [FcPO3Et2]2 ¡¤ZnCl2complex is described. The electrochemical behaviour of FcP(O)(OEt)2, 1,1?-fc[P(O)(OEt) 2]2, FcCH2P(O)(OEt)2, and their corresponding acids were compared. Each of them shows a reversible one-electron transfer reaction. Ferrocenylbisphosphonate is more difficult to oxidize than ferrocenylphosphonate due to the presence of two electron-withdrawing substituents. A methylene spacer between the ferrocenyl unit and the phosphonate group renders the compound easier to oxidize. The acids are easier to oxidize than the esters, and their salts, in which the phosphonate group behave as an electron-donating group, are even easier to oxidize than the ferrocene. The ferrocenylphosphonic acid may be, then, considered as a redox-active pH responsive molecule. Elsevier B.V. All rights reserved.

Biosensors based on electrochemical lactate detection: A comprehensive review

Lactate detection plays a significant role in healthcare, food industries and is specially necessitated in conditions like hemorrhage, respiratory failure, hepatic disease, sepsis and tissue hypoxia. Conventional methods for lactate determination are not accurate and fast so this accelerated the need of sensitive biosensors for high-throughput screening of lactate in different samples. This review focuses on applications and developments of various electrochemical biosensors based on lactate detection as lactate being essential metabolite in anaerobic metabolic pathway. A comparative study to summarize the L-lactate biosensors on the basis of different analytical properties in terms of fabrication, sensitivity, detection limit, linearity, response time and storage stability has been done. It also addresses the merits and demerits of current enzyme based lactate biosensors. Lactate biosensors are of two main types – lactate oxidase (LOD) and lactate dehydrogenase (LDH) based. Different supports tried for manufacturing lactate biosensors include membranes, polymeric matrices-conducting or non-conducting, transparent gel matrix, hydrogel supports, screen printed electrodes and nanoparticles. All the examples in these support categories have been aptly discussed. Finally this review encompasses the conclusion and future emerging prospects of lactate sensors.

alpha-Amino Aldehydes as Readily Available Chiral Aldehydes for Rh-Catalyzed Alkyne Hydroacylation

Readily available alpha-amino aldehydes, incorporating a methylthiomethyl (MTM) protecting group on nitrogen, are shown to be efficient substrates in Rh-catalyzed alkyne hydroacylation reactions. The reactions are performed under mild conditions, employing a small-bite-angle bis-phosphine ligand, allowing for good functional group tolerance with high stereospecificity. Amino aldehydes derived from glycine, alanine, valine, leucine, phenylalanine, isoleucine, serine, tryptophan, methionine, and cysteine were successfully employed, as was an enantiomerically enriched alpha-OMTM-aldehyde derived from phenyllactic acid. The synthetic utility of the alpha-amino enone products is demonstrated in a short enantioselective synthesis of the natural product sphingosine.

(hESC-CMs) intracellular processes and intercellular communication. Methods: Graphene, a honeycomb sp2 hybridized two-dimensional carbon lattice, was synthesized using low pressure chemical vapor deposition system, and was tested for biocompatibility. Au and graphene microelectrode arrays (MEAs) were fabricated using well-established microfabrication methods. Au and graphene MEAs were interfaced with hESC-CMs to perform both optical and electrical recordings. Results: Optical imaging and Raman spectroscopy confirmed the presence of monolayer graphene. Viability assay showed biocompatibility of graphene. Electrochemical characterization proved graphene?s functional activity. Nitric acid treatment further enhanced the electrochemical properties of graphene. Graphene electrodes? transparency enabled both optical and electrical recordings from hESC-CMs. Graphene MEA detected changes in beating frequency and field potential duration upon beta-adrenergic receptor agonist treatment. Conclusion: The transparent graphene platform enables the investigation of both intracellular and intercellular communication processes and will create new avenues for bidirectional communication (sensing and stimulation) with electrically active tissues and will set the ground for investigations reported diseases such as Alzheimer, Parkinson?s disease and arrhythmias.

Molecular and solid state structure of the doubly-substituted ?-diketone 3,3′-bis(ferrocenylmethyl)pentane-2,4-dione

ABSTRACT The ferrocene-containing ?-diketone, 3-ferrocenylmethyl-pentane-2, 4-dione 1, has been synthesized by reacting ferrocenyl methanol with acetylacetone in the presence of cerium(IV) ammonium nitrate as catalyst in C-C bond formation, and isolated as an orange oily product in 90% yield. The doubly-substituted 1,3-diketone, 3,3′-bis(ferrocenylmethyl)pentane-2,4-dione 2 was isolated as orange crystals in 79% yield, upon standing a dichloromethane solution of 1 at -30 C for two weeks. Both complexes have been authenticated by spectroscopic methods, mass spectrometry, and cyclic voltammetry. In addition, the molecular identity and geometry of 2 has been confirmed by single-crystal X-ray diffraction analysis. In the crystal lattice, the molecules pack as dimers through C-HO hydrogen bondings, where weaker C-Hp interactions link the dimeric units to form a chain structure.

COMPLEXATION OF alpha-FERROCENYLMETHYLCARBENIUM TETRAFLUOBORATES BY ETHERS; AN NMR STUDY

The tetrafluoborates of the primary, secondary, and tertiary ferrocenylmethyl carbenium ions have been prepared from the corresponding carbinols in ethyl ether, tetrahydrofuran and t-butyl methyl ether by adding HBF4.The NMR spectra of these salts, which dissolve in CDCl3, are characterized by the presence of very strong signals attributed to the ether used in the preparation, the solubility depending upon the structure of the cation and that of the ether.The NMR data suggest that alpha-ferrocenylcarbenium ions undergo two distinct types of solvation with ether-like donor molecules; one involves a much stronger interaction than the other.

Applications of scanning electrochemical microscopy (SECM) coupled to atomic force microscopy with sub-micrometer spatial resolution to the development and discovery of electrocatalysts

Development and discovery of efficient, cost-effective, and robust electrocatalysts are imperative for practical and widespread implementation of water electrolysis and fuel cell techniques in the anticipated hydrogen economy. The electrochemical reactions involved in water electrolysis, i.e., hydrogen and oxygen evolution reactions, are complex inner-sphere reactions with slow multi-electron transfer kinetics. To develop active electrocatalysts for water electrolysis, the physicochemical properties of the electrode surfaces in electrolyte solutions should be investigated and understood in detail. When electrocatalysis is conducted using nanoparticles with large surface areas and active surface states, analytical techniques with sub-nanometer resolution are required, along with material development. Scanning electrochemical microscopy (SECM) is an electrochemical technique for studying the surface reactions and properties of various types of electrodes using a very small tip electrode. Recently, the morphological and chemical characteristics of single nanoparticles and bio-enzymes for catalytic reactions were studied with nanometer resolution by combining SECM with atomic force microscopy (AFM). Herein, SECM techniques are briefly reviewed, including the AFM-SECM technique, to facilitate further development and discovery of highly active, cost-effective, and robust electrode materials for efficient electrolysis and photolysis.
