Substituent effects in the iron 2p and carbon 1s edge Near-Edge X-ray Absorption Fine Structure (NEXAFS) spectroscopy of ferrocene compounds

The iron 2p and carbon 1s near-edge X-ray absorption fine structure (NEXAFS) spectra of substituted ferrocene compounds (Fe(Cp-(CH3) 5)2, Fe(Cp)(Cp-COOH), Fe(Cp-COOH)2, and Fe(Cp-COCH3)2) are reported and are interpreted with the aid of extended Hiickel molecular orbital (EHMO) theory and density functional theory (DFT). Significant substituent effects are observed in both the Fe 2p and C 1s NEXAFS spectra. These effects can be related to the electron donating/withdrawing properties of the cyclopentadienyl ligands and their substituents as well as the presence of pi* conjugation between the cyclopentadienyl ligand and unsaturated substituents.

Metal-catalyzed electrochemical diazidation of alkenes

Vicinal diamines are a common structural motif in bioactive natural products, therapeutic agents, and molecular catalysts, motivating the continuing development of efficient, selective, and sustainable technologies for their preparation. We report an operationally simple and environmentally friendly protocol that converts alkenes and sodium azide?both readily available feedstocks?to 1,2-diazides. Powered by electricity and catalyzed by Earth-abundant manganese, this transformation proceeds under mild conditions and exhibits exceptional substrate generality and functional group compatibility. Using standard protocols, the resultant 1,2-diazides can be smoothly reduced to vicinal diamines in a single step, with high chemoselectivity. Mechanistic studies are consistent with metal-mediated azidyl radical transfer as the predominant pathway, enabling dual carbon-nitrogen bond formation.

Some insights into the gold-catalysed A3-coupling reaction

A series of cyclometallated and functionalised NHC gold(I) and gold(III) complexes, many of which feature chiral ligands, and their application to A3-coupling reactions is presented. Gold(III) complexes were found to be particularly effective catalysts for the coupling in a range of solvents, however no asymmetric induction was obtained when using chiral gold complexes and the rate of product formation was found to be similar even when using different ligand systems. In-situ NMR analysis of these reactions indicates that decomposition of the catalyst occurs during the course of the reaction while TEM studies revealed the presence of gold nanoparticles in crude reaction mixtures. Taken together these data suggest that the gold nanoparticles, rather than the intact gold complexes, could be the catalytically active species, and if so this may have significant implications for other gold-catalysed systems.

Biodegradable electroactive polymers for electrochemically-triggered drug delivery

We report biodegradable electroactive polymer (EAP)-based materials and their application as drug delivery devices. Copolymers composed of oligoaniline-based electroactive blocks linked to either polyethylene glycol or polycaprolactone blocks via ester bonds were synthesized in three steps from commercially available starting materials and isolated without the need for column chromatography. The physicochemical and electrochemical properties of the polymers were characterized with a variety of techniques. The ability of the polymers to deliver the anti-inflammatory drug dexamethasone phosphate on the application of electrochemical stimuli was studied spectroscopically. Films of the polymers were shown to be degradable and cell adhesive in vitro. Such EAP-based materials have prospects for integration in implantable fully biodegradable/bioerodible EAP-based drug delivery devices that are capable of controlling the chronopharmacology of drugs for future clinical application.

Organometallic Derivatization of the Nematocidal Drug Monepantel Leads to Promising Antiparasitic Drug Candidates

The discovery of novel drugs against animal parasites is in high demand due to drug-resistance problems encountered around the world. Herein, the synthesis and characterization of 27 organic and organometallic derivatives of the recently launched nematocidal drug monepantel (Zolvix) are described. The compounds were isolated as racemates and were characterized by1H,13C, and19F NMR spectroscopy, mass spectrometry, and IR spectroscopy, and their purity was verified by microanalysis. The molecular structures of nine compounds were confirmed by X-ray crystallography. The anthelmintic activity of the newly designed analogues was evaluated in vitro against the economically important parasites Haemonchus contortus and Trichostrongylus colubriformis. Moderate nematocidal activity was observed for nine of the 27 compounds. Three compounds were confirmed as potentiators of a known monepantel target, the ACR-23 ion channel. Production of reactive oxygen species may confer secondary activity to the organometallic analogues. Two compounds, namely, an organic precursor (3 a) and a cymantrene analogue (9 a), showed activities against microfilariae of Dirofilaria immitis in the low microgram per milliliter range.

The remarkable behavior of crystalline [Fe(eta5-C5H4CHO)2]: Two solid-to-solid phase transitions and a solid-state reaction

The crystal architecture, stability, and behavior with temperature of bis(formyl)ferrocene, [Fe(eta5-C5H4CHO)2], have been investigated by variable-temperature X-ray diffraction experiments, differential scanning calorimetry, and thermogravimetry experiments. [Fe(eta5-C5H4CHO)2] is present with two independent molecules with cisoid and transoid relative orientations of the two formyl groups in the crystals obtained from the reaction sequence (phase RT-1). The role of C-H- – -O interactions involving the formyl groups has been examined. When RT-1 is heated, the first irreversible phase transition to a plastic phase (phase HT) is observed at ca. 38C (311 K). When it is cooled, phase HT transforms into a new room-temperature phase (RT-2). Once RT-2 has been formed, the system switches reversibly between HT and RT-2 (transition temperature in the heating cycles ca. 35C), while RT-1 can no longer be obtained. Further heating of phase HT shows the occurrence of an exothermic reaction at ca. 150C (423 K) leading to the formation of a ferrocene-based polymer.

Hydrogen and Atom Transfer Activity of Saffron Extracts by Square Wave Voltammetry

Saffron is an edible spice with highly appreciated sensory and antioxidant properties. One of the most representative redox species found in saffron extracts is crocin, whose content is used to evaluate the quality and value of the resulting spice. In this study, a voltammetry method based on the direct detection of crocin at a bare glassy carbon electrode is presented. The principle of the method is based on the monitoring of the anodic wave exhibited by crocin (0.1?1.0 mM) after its mixing with the azo radical initiator AAPH (20 mM) in ethanol:acetonitrile (1 : 1) solution. The decay rate of the anodic peak (E=+434 mV vs. Ag/Ag+), as a result of the consumption of crocin by AAPH, was used as index of the hydrogen transfer capacity and, thus, of its antioxidant activity. With a decay rate of k=0.02 h?1, crocin exhibits only a weak antioxidant activity in comparison with tocopherols (k=0.13 h?1), but still sufficient to protect against the oxidation of safranal, a further redox species found in saffron extracts and mainly responsible for its flavor. The proposed approach was finally applied to discriminate saffron extract samples from different geographical origins. The proposed approach is suitable to characterize the quality of saffron extracts and estimate its antioxidant properties.

Efficient regio- and diastereo-controlled synthesis of 1,1?- and 1,1?,2,2?-functionalised ferrocenes and the formation of 2-oxa[3]ferrocenophanes

The synthesis of a C2 symmetric 1,1? ,2,2?-tetrasubstituted ferrocene system was discussed. The route involved the reduction of ferrocenyl carbonyl compounds which gave access to a range of alcohols, alkenes, alkanes, ethers, and 2-oxa[3]ferrocenophanes depending on the precise conditions used. The loss of optical activity of 1,1?-bis(hydroxymethyl)ferrocenes and 1,1?-bis(hydroxymethyl)ruthenocenes, which had been prepared by asymmetric reduction, was demonstrated in an acidic medium by extensive 1H NMR studies.
