A series of 1,1?-ferrocenyldiimines [Fe{(eta5-C5H4)-C(Me)N-R}2 ], where R = n-hexyl 1a, cyclohexyl 1b, phenyl 1c, 4-methoxyphenyl 1d, 3-methoxyphenyl 1e, 4-nitrophenyl 1f, and 3-nitrophenyl 1g, have been synthesized by reactions of ca. 1:2 M ratio of 1,1?-diacetylferrocene and the corresponding amines. While ca. 1:1 M ratio of the starting materials was employed, acetylferrocenylimines [Fe{(eta5-C5H4)-C(CH3){dou ble bond, long}O}{(eta5-C5H4)-C(CH3) {double bond, long}N-R}], where R = 4-nitrophenyl 2f, and 3-nitrophenyl 2g, were obtained. Single crystal X-ray structural analysis revealed that the two cyclopentadienyl rings in 1d, 1e, 1g, 2f, and 2g were antiperiplanar staggered, anticlinal eclipsed, anticlinal eclipsed/synclinal eclipsed, synclinal eclipsed, and synclinal eclipsed to each other in solid state, respectively. All synthesized ferrocene derivatives exhibited a reversible one-electron redox process in their cyclic voltammograms, and the values of their redox potentials relied on the R groups. The correlation between the redox potential and the Hammett substituent constant, sigmap was quite well, with a correlation coefficient of 0.98. The UV-vis spectra showed that their optical property was also substituent dependent.

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.

The structure of water in 70 wt % sorbitol-30 wt % water mixture is investigated by wide-angle neutron scattering (WANS) as a function of temperature. WANS data are analyzed using empirical potential structure refinement to obtain the site-site radial distribution functions (RDFs). Orientational structure of water is represented using OW-OW-OW triangles distributions and a tetrahedrality parameter, q, while water-water correlation function is used to estimate size of water clusters. Water structure in the sorbitol matrix is compared with that of water confined in nanopores of MCM41. The results indicate the existence of voids in the sorbitol matrix with the length scale of approximately 5 A, which are filled by water. At 298 K, positional water structure in these voids is similar to that of water in MCM41, whereas there is a difference in the tetrahedral (orientational) arrangement. Cooling to 213 K strengthens tetrahedrality, with the orientational order of water in sorbitol becoming similar to that of confined water in MCM41 at 210 K, whereas further cooling to 100 K does not introduce any additional changes in the tetrahedrality. The results obtained allow us to propose, for the first time, that such confinement of water in a sorbitol matrix is the main reason for the lack of ice formation in this system.

We describe an eco-friendly, practical and operationally simple procedure for the bis(methoxypropyl) ether-promoted oxidation of aromatic alcohols into aromatic carboxylic acids and aromatic ketones with atmospheric dioxygen as the sole oxidant. This chemical process is clean with high conversion and good selectivity, and an external initiator, catalyst, additive and base are not required. The virtue of this reaction is highlighted by its easily available and economical raw materials and excellent functional group tolerance (acid-, base- and oxidant-labile groups).

Introducing a new discovery about 1273-86-5, Name is Ferrocenemethanol

3,3?,5,5?-Tetramethylbenzidine (TMB) has been frequently used as an indicator in G-quadruplex/hemin DNAzyme (G4zyme)-based chemical and biochemical analysis, and its oxidation products are usually monitored by electrochemical or optical methods to quantify G4zyme formation-related analytes. Herein we report a simple electrochemical approach based on isoporous silica-micelle membrane (iSMM) to measure TMB, instead of its oxidation products, in G4zyme-based detection of specific analytes. The iSMM was grown on the indium tin oxide (ITO) electrode, which was composed of highly ordered, vertically oriented silica nanochannels and cylindrical micelles of cetyltrimethylammonium. The iSMM-ITO electrode was selectively responsive to neutral TMB but not its oxidation products, thanks to the sieving and pre-concentration capacity of micellar structures in terms of molecular charge and lipophilicity. In other words, only TMB could be extracted and enriched into micelles and subsequently oxidized at the underlying ITO electrode surface (namely the micelle/ITO interface), generating an amplified anodic current. Since the depletion of TMB was catalyzed by G4zymes formed in the presence of specific analyte, the decrease of this anodic current enabled the quantitative detection of this analyte. The current variation relative to its initial value ((j0?j)/j0), termed as the current attenuation ratio, showed the obvious dependence on the analyte concentration. As proof-of-concept experiments, four substances, i.e., potassium cation (K+), adenosine triphosphate, thrombin and nucleic acid, were detected in aqueous media and the analysis of K+ in pre-treated human serum was also performed.

Two novel isoxazoline N,N-bidentate ligands with ferrocene backbone have been synthesized and employed for the palladium-catalyzed Heck coupling reaction. Among them, 1,3-bis-(5-ferrocenylisoxazoline-3-yl)benzene was found to be thermally stable and a highly effective ligand for Heck coupling reaction in neat water without N2 protection, affording the desired coupling products in good to excellent yield with high diastereoselectivity. The developed catalytic system was also well workable for 1,2-disubstituted alkenes, which were less involved in the Heck reaction for its larger steric hindrance. Copyright

The binding properties of azole drugs toward ferric heme have been examined, focusing on well known antifungal drugs bearing imidazole and triazole heteroaromatic rings. These drugs are known to act as inhibitors of the Candida albicans P450 sterol 14alpha-demethylase enzyme, through binding to the heme prosthetic group. Absolute binding energies have been determined experimentally by energy variable collision induced dissociation experiments performed on the selected ionic complexes and evaluated theoretically using density functional theory, within the Car-Parrinello Molecular Dynamics method. The two series display some agreement in the relative binding energies data. These findings suggest that the combined ab initio and mass spectrometric approach may prove fruitful in assaying complexes between a prosthetic group and an array of ligands of potential pharmacological activity. It is shown that the axial interaction of the imidazole-based drugs with iron(III) is somewhat stronger than that of the triazole-based drugs. This general observation fails if specific interactions remote from the metal center come into play. For example, a hydrogen bond interaction is established in the ferric heme complex with fluconazole, a drug of the triazole family owning a hydroxyl group prone to interact with the carbonyl oxygen of a propionyl group on the periphery of protoporphyrin IX. However, the relatively uniform values for both the experimental and theoretically calculated binding energies underline the important role played by the prosthetic group environment in tuning the heme interaction with biological and xenobiotic molecules and ultimately in modulating enzyme activity.

The synthesis of four new 1,2,3-triazole derivatives and seven 1,2,3-triazolium salts that contain an organometallic group (i.e., cymantrenyl and ferrocenyl) at either the N-1, N-2, or N-3 position was realized. The alkylation of organometallic and organic triazole derivatives was investigated, and as a result of these studies, it was found that the presence of a good leaving group at the heterocyclic nitrogen atom led to transalkylation and subsequent migration of the N-1 substituent to the N-2 position of the triazole moiety. The nucleophilicity of the counterion of the triazolium salt influenced the transalkylation and isomerization processes, which suggests that the elimination of the N-substituent most likely occurs though a concerted mechanism with nucleophilic assistance from the counterion. Thus, a new approach to the synthesis of 2,4-disubstituted 1,2,3-triazoles has been developed.
