Thiel, W. published the artcileDithiocarboxylic acids, dithiocarboxylic esters, or thiocarboxylic amides by reaction of methylene-active chloromethyl compounds with sulfur, SDS of cas: 4760-35-4, the publication is Journal fuer Praktische Chemie (Leipzig) (1989), 331(2), 243-62, database is CAplus.

With a mixture of S and amine in DMF at room temperature halomethyl compounds can be oxidized to give thiocarboxylic acids and their derivatives The reaction was studied in detail especially with chloroacetic derivatives or chloromethyl heterocycles formally derived from chloroacetic acid. The resulting thiooxalic acid derivatives represent activated acids and very useful C₂-synthons, especially for the synthesis of heterocycles. Oxidation in the presence of Et₃N leads to dithiocarboxylates which can be alkylated to dithioesters in high yields. As a rule, with different primary and secondary amines instead of tertiary amines these dithiocarboxylates or dithiocarboxylic esters can be transformed already at low temperatures to thioamides.

Han, Yali published the artcileHalf-sandwich Iridium(III) Benzimidazole-Appended Imidazolium-Based N-heterocyclic Carbene Complexes and Antitumor Application, Recommanded Product: 2-(Chloromethyl)-1-methyl-1H-benzo[d]imidazole, the publication is Chemistry – An Asian Journal (2018), 13(23), 3697-3705, database is CAplus and MEDLINE.

A series of half-sandwich iridium(III) benzimidazole-appended imidazolium-based N-heterocyclic carbene (NHC) antitumor complexes [(η⁵-Cp^x)Ir(CN̂)Cl]Cl, where Cp^x is pentamethylcyclopentadienyl (Cp*) or its biphenyl derivative (Cp^xbiph) and CN̂ is a NHC chelating ligand, were successfully synthesized and characterized. The Ir^III complexes showed potential antitumor activity against A549 cells, at most three times more potent than cis-platin under the same conditions. Complexes could bind to BSA by a static quenching mode, catalyzing the change of NADH to NAD⁺ and inducing the production of reactive oxygen species (maximum turnover number, 9.8), which play an important role in regulating cell apoptosis. Confocal microscopy showed that the complexes could specifically target lysosomes in cells with a Pearson’s co-localization coefficient 0.76 and 0.72 after 1 h and 6 h, resp., followed an energy-dependent cellular uptake mechanism and damaged the integrity of lysosomes. At the same time, complexes caused a marked loss of mitochondrial membrane potential.

A new iron complex mediates stereospecific hydroxylation of alkyl C-H bonds with hydrogen peroxide, exhibiting excellent efficiency. Isotope labeling studies provide evidence that the relative reactivity of tautomerically related oxo-iron species responsible for the C-H hydroxylation reaction is dominated by steric factors.

Jia, Hongxing published the artcileIn situ anodic electrodeposition of two-dimensional conductive metal-organic framework@nickel foam for high-performance flexible supercapacitor, Safety of 3-Butyl-1-methyl-1H-imidazol-3-ium chloride, the publication is Journal of Power Sources (2022), 231163, database is CAplus.

Owing to their large sp. surface area and well-defined porosity, metal-organic frameworks (MOFs) have long been considered as promising materials for energy storage. Unfortunately, their straightforward utilization in supercapacitors was hindered for years due to poor conductivity until the emergence of 2D conductive MOF materials. To date, several 2D conductive MOF-based supercapacitors have been reported. Nevertheless, almost all these supercapacitors were fabricated from MOF powders through a slurry coating method or dense packing method, which neg. affected their capacitor performance. Herein, we have developed an anodic electrodeposition (AED) approach to fabricate a uniformly deposited 2D conducting MOF on nickel foam and use it directly as electrodes for supercapacitors without any additives. The superior performance of the 2D conducting MOF on nickel foam in both aqueous and organic electrolytes was then disclosed by a series of electrochem. measurements, demonstrating the significant advantages of the AED approach over traditional methods.

Li, Dandan published the artcileIntensifying the moderate electric field-induced modification of maize starch by 1-butyl-3-methylimidazolium chloride, Synthetic Route of 79917-90-1, the publication is Carbohydrate Polymers (2022), 119654, database is CAplus and MEDLINE.

This study aimed to improve the effect of moderate elec. field (MEF) treatment on the structural and physicochem. properties of maize starch by adding 1-butyl-3-methylimidazolium chloride ([bmim]Cl). Starch (20%, w/v) was mixed with [bmim]Cl solution (0, 30%, 50%, and 70%, weight/weight), and then electro-treated (5 V/cm, 50 Hz) at 60 °C for 10 min. As the [bmim]Cl concentration increased, the electro-induced disintegration of starch granules was enhanced due to the intensified Joule heat and decreased pH of reaction bulk. After electro-treated in 70% weight/weight [bmim]Cl, a transparent solution of starch was observed and the recovered starch tended to dissolve rather than swell in water. Compared with water-bath heating, MEF caused more destruction in the granular and crystal structure, increased the particle size, decreased the pasting viscosity, and reduced the gelatinization enthalpy and thermostability of starch. The obtained results could provide guidance for the application of electro-based techniques in starch modification.

Wu, Wenna published the artcilePolyelectrolyte aerogels with regeneration capacity for efficient removal of particulate matters, Formula: C8H15ClN2, the publication is Journal of Colloid and Interface Science (2022), 446-456, database is CAplus and MEDLINE.

With the rapid development of economy and global industrialization, the problem of air pollution has become a worldwide topic. The efficient filtration of airborne particulate matters (PMs) is critical for human health and environmental sustainability. Herein, self-supporting bio-based polyelectrolyte aerogels were prepared and acted as the advanced filters for efficient removal of PMs. The natural choline cation (Ch⁺) or the organic cation, 1-butyl-3-methylimidazolium (Bmim⁺), are introduced into alginate (Alg^–) to form the polyelectrolytes of ChAlg or BmimAlg due to the electrostatic interaction. By the directional freeze-drying in liquid N₂, hierarchically porous aerogels with mech. robustness, flexibility and thermo-stability were prepared This specific structure may permit the polluted air to pass adequately through the aerogel channels, which are conducive to intercept various PMs with different diameters As an example, the removal efficiency of ChAlg aerogels for PM₁₀, PM_2.5 and PM_0.3 are resp. up to (99.24 ± 0.03)%, (99.22 ± 0.02)%, and (93.41 ± 0.22)% within 15 h durability test. One outstanding character lies in ensuring high removal efficiency, while achieving a good balance with the low pressure drop (10 Pa), which is driven by synergistic effect of passive trapping and electrostatic capture. Moreover, the polyelectrolyte aerogels exhibit excellent antimicrobial activity and regenerated capacity. These properties endow the aerogels of polyelectrolyte ChAlg or BmimAlg with remarkable potential as new advanced filters for masks and other personal protective equipment.

Song, Xiangbo published the artcileA highly effective approach to enhance the performance of biomass-derived acid for fructose conversion to 5-hydroxymethylfurfural, Product Details of C8H15ClN2, the publication is Fuel Processing Technology (2022), 107318, database is CAplus.

Synthesis of 5-hydroxymethylfurfural (HMF) from carbohydrate is one of vital step for bio-refinery development. In this work, a novel strategy was developed for catalytic conversion of fructose to HMF in 2-butanol. The inexpensive ionic liquids were used to adjust the acidity of biobased acid catalyst for enhancing the dehydration of fructose to HMF. The combination of 1-butyl-3-methylimidazolium chloride ([Bmim]Cl) with oxalic acid afforded an excellent HMF yield of 97.1% at 98.7% fructose conversion under mild conditions of 100°C and 60 min, owing to the enhanced dissociation ability of oxalic acid by [Bmim]Cl. A possible dissociation mechanism of oxalic acid induced by [Bmim]Cl was proposed based on control experiments and detailed analyses with NMR and FT-IR techniques. It involved that the [Bmim]Cl interacted with oxalic acid through hydrogen bond, which decreased the electron d. of oxygen atom on hydroxyl group and weakened the O-H bond, thus making the hydrogen in the O-H group to easily dissociate in the form of H⁺. Moreover, the reusability of oxalic acid and [Bmim]Cl was demonstrated, and both could be reused up to six times without significant loss in activity.
