The reaction of antimony(III) chloride with 1,4-dithiane (1,4-dt) in the ionic liquid [BMIM]Cl ([BMIM]Cl: 1-butyl-4-methylimidazolium chloride) with an excess of the Lewis acid AlCl3 results in the formation of a ligand-stabilized stibenium cation [SbCl2]. 1,4-Dithiane simultaneously serves as a chelating η2-ligand, exhibiting a boat-like conformation, as well as a bridging μ2-ligand, exhibitin...

Precipitation patterns emerging in a two-dimensional moving front are investigated on the example of NaOH diffusing into a gel containing AlCl3 . The time evolution of the precipitate Al(OH)_{3} can be observed since the precipitate redissolves in the excess outer electrolyte NaOH and thus it exists only in a narrow optically accessible region of the reaction front. The patterns display self-si...

Methanolic extracts of 13 commercially available citrus spp., peels and tissues growing in Iran were investigated for their antioxidant activity by DPPH method. IC50 for antioxidant activity ranged from 0.6-3.8 mg ml(-1). Total phenolic content of the citrus spp. samples (based on folin Ciocalteu method) varied from 66.5 to 396.8 mg gallic acid equivalent/g of extract and flavonoids content (ba...

Dimensional Confinement In article number 2105898, Yung-Chang Lin, Kazu Suenaga, and co-workers report the discovery of a new AlCl3 structure in 2D form. Metal chlorides such as CuCl2 intercalated bilayer graphene are found to have polymorphic phases, which not been previously expected bulk. Utilizing dimensional confinement, growth further unexpected materials nanospace between is expected.

The adsorption of AlCl3 on Si(100) and the effect annealing AlCl3-dosed substrate were studied to reveal key surface processes for development atomic-precision, acceptor-doping techniques. This investigation was performed via scanning tunneling microscopy (STM), X-ray photoelectron spectroscopy (XPS), density functional theory (DFT) calculations. At room temperature, readily adsorbed Si dimers ...

Alzheimer’s disease (AD) is a neurological episode associated with the senescence process characterized by neuronal cell death in brain regions and loss of cognition. The study investigate neuroprotective potentials Moringa oleifera leaf extract Neostigmine rat model induced Aluminium chloride (AlCl3). A total number 20 rats weighing 180-240 kg were used for this they grouped into 5 4 each grou...

Activation of the purified guanine nucleotide-binding regulatory component (G/F) of adenylate cyclase by F- requires the presence of Mg2+ and another factor. This factor, which contaminates commercial preparations of various nucleotides and disposable glass test tubes, has been identified as Al3+. In the presence of 10 mM Mg2+ and 5 mM F-, AlCl3 causes activation of G/F with an apparent activat...

1-(Diphenylphosphoryl)alka-1,2-dienes (phosphonoallenes) in Brønsted (super)acids (TfOH, FSO3H, and H2SO4) at -70 to 120 °C for 30 min to 4 h gave, at first, (3-hydroxyalk-1-en-1-yl)diphenylphosphine oxides, as kinetically favorable reaction products, that are further converted into 1-phenyl-1,4-dihydrophosphinoline 1-oxides as thermodynamically stable compounds. The latter compounds are formed...

A novel cyclization reaction of ethenetricarboxylate derivative aromatic compounds in the presence of various Lewis acids gave benzo-annulated cyclic compounds such as oxindole and benzofuran derivatives via Friedel-Crafts intramolecular Michael addition in high yields. For example, the reaction of diethyl 2-[(N-methyl-N-phenylcarbamoyl)methylene]malonate (1a) in the presence of ZnCl2 at room t...
