Four new ferrocenyl-flavone complexes were obtained via palladium-catalyzed Heck cross-coupling reactions; (E)-6-ferrocenylvinyl-chromen-4-one (4), (E)-6-ferrocenylvinyl-2-methyl-chromen-4-one (5), (E)-6-ferrocenylvinyl-2- phenyl-chromen-4-one (6) and (E)-6-ferrocenylvinyl-chromen-4-one-3-propionic acid (7). All compounds were characterized by 1H NMR, 13C NMR, IR spectroscopy, high resolution-MS, elemental analysis and cyclic voltammetry. The molecular structure of derivatives 4 and 6 was also confirmed by X-ray crystallography. The biological activity of the complexes was rationalized on the basis of their anticancer and antibacterial properties. The anticancer activity of ferrocenyl-flavones 4 e7 against established human cell lines derived from hematological and solid tumors has been evaluatedin vitro. The following cell lines were investigated: MCF-7 (estrogen receptor-responsive breast adenocarcinoma), MDA-MB-231 (estrogen receptor-negative breast adenocarcinoma), HepG2 (hepatocellular carcinoma) and CCRF-CEM (T lymphoblast-like polymorph cells). All investigated ferrocenyl-flavones show cytotoxicity against CCRF-CEM cell line. The antibacterial activity of the four ferrocenyl-flavones against Gram-positive methicillin-sensitive Staphylococcus aureus (MSSA), methicillin-resistant S. aureus (MRSA), vancomycin-resistant S. aureus (VRSA) and Staphylococcus epidermidis bacterial strains was determined. Our experiments show antibacterial activity for the carboxylic acid derivative 7 against all tested Gram-positive bacterial strains while no activity was detected for the ferrocene-free 6-bromo-chromen-4-one-3-propionic acid.

Ferrocenyl-substituted bicyclo[1.1.1]pentasilanes 1, 2, and 3 were synthesized by the reactions of bromo-substituted bicyclo[1.1.1]pentasilanes with lithioferrocene. Significant interactions between bicyclo[1.1.1]pentasilane and ferrocenyl units were suggested by cyclic voltammetry, UVvis absorption spectrum, and theoretical calculations.

The potential use of (aminomethyl)ferrocene and 1,1? -di(aminomethyl)ferrocene as precursor for Schiff base chemistry has been tested. (Aminomethyl)ferrocene reacts with 3,3? -(3-oxapentane-1,5-diyldioxy)bis(2-hydroxybenzaldehyde) to give the [2+1] diiminic ligand 8. 8 reacts with LaCl3 and Ni(CH3COO) 2 giving the corresponding complexes 9 and 10. 1,1? -Di(aminomethyl)ferrocene was prepared by conversion of 1,1? -di(formyl)ferrocene into 1,1?-di(formyl)ferrocene oxime, followed by reduction of the oxime with LiAlH4. Easy degradation of 1,1?-di(aminomethyl)ferrocene prevented its use as aminic precursor for the synthesis of Schiff base ligands. Isomerization occurred about the carbon-nitrogen double bonds of 1,1?-di(formyl)ferrocene oxime giving rise to three isomers. The X-ray analysis has shown that in the 5a complex three independent molecules having different conformation are present.

Scanning electrochemical microscopy (SECM) can image graphene oxide (GO) flakes on insulating and conducting substrates. The contrast between GO and the substrate is controlled by the electrostatic interactions that are established between the charges of the molecular redox mediator and the charges present in the sheet/substrate. SECM also allows quantitative measurement-at the nano/microscale-of the charge transfer kinetics between single monolayer sheets and agent molecules. This journal is

In this work, we have studied the formation of complexes between flavonols, (quercetin, rutin, quercitrin, kaempferol, luteolin, tamarixetin) and flavanols ((+)-catechin, (-)-epicatechin), flavanonol, (+)-taxifolin, and Zn acetate in two hydro-organic media at neutral pH in the absence of oxygen. The complexation was first studied by cyclic voltammetry. Then preparative electrolysis have been attempted followed by coulometry, UV-Vis optical absorption and circular dicroism spectroscopies for characterizing the oxidized compounds. Spectroelectrochemistries monitored either in the UV-Vis or in the EPR spectrometers at room temperature have been also used and we have identified o-semi-quinone intermediates in some cases. Different behaviour vis-a-vis the complexation by Zn2+ according to the molecular structures of these different families of polyphenols have been found. Some of them are more easily oxidizible.

In a document type is Article, and a compound is mentioned, 1273-86-5, name is Ferrocenemethanol, introducing its new discovery.

The direct high-yield synthesis without solvent and catalyst, under mild conditions, of eleven novel mono substituted ferrocenylmethyl ethers and amine derivatives from ferrocenemethanol and vicinal oxygenated alcohols and amines is here reported. The peculiar ability of these classes of non acidic compounds to favor the dehydrative nucleophilic substitution is attributed to the presence of vicinal oxygen atoms to the reactive group able to build a hydrogen bonding network with the reactant. The role of carbon dioxide and hexafluoroisopropanol was investigated to support the hypothesis that a template catalysis effect is occurring. The in vitro anti-fungal activity of some of these derivatives was tested on two plant fungi, Botrytis cinerea and Penicillium species, with moderate activity.

Therefore, this conceptually novel strategy might open impressive avenues to establish green and sustainable chemistry platforms. In my other articles, you can also check out more blogs about 1273-86-5

The protection performance of self-assembled monolayers (SAMs) formed by 2-(Pyridin-2-yliminomethyl)-phenol (HL) on the surface of copper has been studied in situ with the scanning electrochemical microscope (SECM). The pitting dynamic processes were observed in sodium chloride solution without the presence of SAMs, but they tended to be inhibited by SAMs if the assembly time was long enough. During the scanning process, the self-assembled method decreases the interaction between the HL molecules and the SECM tip greatly.

Non-aqueous redox flow batteries, because of larger operating voltage, have attracted considerable attention for high-density energy storage applications. However, the study of the anolyte is rather limited compared with the catholyte due to the labile properties of redox mediators at low potentials. Here, we report a new strategy that exploits high concentration organic lithium metal solution as a robust and energetic anolyte. The solution formed by dissolving metallic lithium with biphenyl (BP) in tetraethylene glycol dimethyl ether (TEGDME) presents a redox potential of 0.39 V versus Li/Li+, and a concentration up to 2 M. When coupled with a redox-targeted LiFePO4 catholyte system, the constructed redox flow lithium battery full cell delivers a cell voltage of 3.0 V and presents reasonably good cycling performance.

Therefore, this conceptually novel strategy might open impressive avenues to establish green and sustainable chemistry platforms. In my other articles, you can also check out more blogs about 1293-65-8
