Cyclic azomethine imines possessing a beta-aminocarbonyl motif are accessed from simple alkene and hydrazone starting materials. A thermal, concerted alkene aminocarbonylation pathway involving an imino-isocyanate intermediate is proposed and supported by DFT calculations. A notable feature of the process is the steric shielding present in the dipoles formed, which allows for facile purification of the products by chromatography or crystallization. In addition, a fluorenone-derived reagent is reported, which provides reactivity with several alkene classes and allows for mild derivatization of the dipoles into beta-aminoamides, beta-aminoesters, and beta-amino acids.

In a article, mentioned the application of 1271-48-3, Name is 1,1′-Ferrocenedicarboxaldehyde, molecular formula is C12H10FeO2

By means of base-catalysed condensation of 1-acyl-/1,1?- diacylferrocenes (acylformyl or acetyl) with 3-formyl- and 3,7- diacetylphenothiazines a series of novel mono- and bis-chalcones were prepared. The enhanced reactivity of the enolate anions of the mono-chalcone intermediates relative to that of the enolates of the corresponding diacetyl-substituted precursor was interpreted by the electron-releasing effect of the ferrocenyl- or phenothiazinyl group present in the beta position of the enone subunit. The structures of the novel products were evidenced by IR, 1H and 13C NMR spectroscopy including 2D-COSY, 2D-HSQC and 2D-HMBC measurements.

Scanning electrochemical microscopy (SECM) is unique among scanning probe methods in its quantitative rigor and in its ability to study samples in liquid environments with ease. SECM has become a popular and mature technique with a wide range of applications in electrochemical imaging, chemical kinetics, biological redox processes, and electrocatalytic reactions, among others. A major development in recent years is the ongoing shift from micrometer-scale experiments to the nanoscale. Recent advances in methodology have greatly increased the capacity of SECM to characterize interfaces at the nanoscale and to obtain molecular-level chemical information. The principles of SECM will be briefly introduced, and recent advances using this technique will be discussed.

The diffusion of ferrocene methanol in super-cooled aqueous solutions containing sucrose has been studied, using disk and cylindrical microelectrodes, over a wide viscosity range. The solution viscosity and the reduced temperature T/Tg (Tg being the glass transition temperature) were varied by changing the sucrose concentration and the temperature of the system. The voltammetric limiting current obtained with a disk microelectrode and the i(t) response on a cylindrical microelectrode after a potential step were used to determine diffusion coefficients from 7 × 10-6 cm2 s-1 down to 2 × 10-11 cm2 s-1. The electrochemical procedure described in this work allows a simple and accurate measurement of the dynamics of electroactive solutes in glass-forming liquids.

Synthesis, structure determination and in vitro antiproliferative assay of a series of novel ferrocenenyl hydrazones containing 4-halopyridazin-3(2H)-one fragment(s) and three representative N-arylsubstituted (Sp)-ferroceno[d] pyridazinones are presented. The model compounds can be considered as different assemblies of the potential binding sites capable of establishing interactions including hydrogen bonds and pi-pi interactions with the relevant residues of biomolecules. Their in vitro antiproliferative effect was investigated against four tumorous cell lines by the 3-(4,5-dimethylthiazol-2-yl)-2,5- diphenyltetrazolium bromide (MTT)-assay. Our data indicate that bis-hydrazone of 1,1?-diformylferrocene carrying N-benzyl substituents and a chloropyridazinyl-substituted ferroceno[d]pyridazinone display significant activity on each cell lines investigated. The efficiency of the latter drug candidate and one N-benzyl mono-hydrazone on A2870 cell line is comparable to that of cisplatin. The constitution and relative configuration of the model compounds were established by 1H, 13C and 15N NMR methods. The structures of a mono- and bis-ferrocenylhydrazone containing 4-bromopyridazinone unit(s) were confirmed by single crystal X-ray diffraction.
