And the article contained the following:

The cleavage of aryl Me ethers is a common reaction in chem. requiring rather harsh conditions; consequently, it is prone to undesired reactions and lacks regioselectivity. Nevertheless, O-demethylation of aryl Me ethers is a tool to valorize natural and pharmaceutical compounds by deprotecting reactive hydroxyl moieties. Various oxidative enzymes are known to catalyze this reaction at the expense of mol. oxygen, which may lead in the case of phenols/catechols to undesired side reactions (e.g., oxidation, polymerization). Here an oxygen-independent demethylation via Me transfer is presented employing a cobalamin-dependent veratrol-O-demethylase (vdmB). The biocatalytic demethylation transforms a variety of aryl Me ethers with two functional methoxy moieties either in 1,2-position or in 1,3-position. Biocatalytic reactions enabled, for instance, the regioselective monodemethylation of substituted 3,4-dimethoxy phenol as well as the monodemethylation of 1,3,5-trimethoxybenzene. The methyltransferase vdmB was also successfully applied for the regioselective demethylation of natural compounds such as papaverine and rac-yatein. The approach presented here represents an alternative to chem. and enzymic demethylation concepts and allows performing regioselective demethylation in the absence of oxygen under mild conditions, representing a valuable extension of the synthetic repertoire to modify pharmaceuticals and diversify natural products. The experimental process involved the reaction of 1,2-Dimethoxybenzene(cas: 91-16-7).Safety of 1,2-Dimethoxybenzene

And the article contained the following:

The design and synthesis of a library of natural product inspired benzocoumarin-chalcones chimeras, as potent and selective, novel, anti-breast cancer scaffold, is reported herein. Twenty-one new chimeric mols., 25-45, were synthesized through an efficient protocol involving the Horner-Wadsworth-Emmons-olefination of β-aryl-β-ketophosphonates with 4-formyl-2H-benzo[h]chromen-2-ones as the key step, and evaluated for anti-proliferative activity against a panel of four breast cancer and related cell lines viz. MDA-MB-231 (ER-ve), MCF-7 (ER+ve), Ishikawa (endometrial cancer) and Hela (cervical cancer). The synthesized mols. showed in vitro anti-proliferative activity in a range of 7.42 to 74.68 μM (IC50). Compounds 33 and 34 showed very good activity, with 34 exhibiting better activity than the standard drugs, tamoxifen and raloxifene. Interestingly, none of the compounds showed cytotoxity against the normal human cell line. To identify the possible targets of the active compounds, mol. docking anal. was conducted to correlate their interaction with the ERα and ERβ receptors. From among the active compounds the docked conformations of 34, at the ERα and ERβ active sites, showed that it fits most favorably in the ligand binding space and shows hydrophobic interactions with the salient residues. Based on the above findings, 34 was identified as a lead mol. for development of more potent anti-breast cancer agents. The experimental process involved the reaction of 2-Methylanisole(cas: 578-58-5).Computed Properties of 578-58-5

And the article contained the following:

Because of the application of treating hazardous wastes such as organic dyes and radioactive iodine, the porous carbon with high adsorption capacity has been a research hotspot. In this work, by the pyrolysis method with KOH activation, the hypercrosslinked polynaphthalenes were used as carbonaceous precursors to prepare porous carbons, which showed high sp. surface areas between 943.8 and 2754.5 m2 g-1 with high micropore ratios.

Pelayo Garcia; Sargent, Edward H.; Park, Taiho published an article.Category: ethers-buliding-blocks The title of the article was Efficient and Stable Colloidal Quantum Dot Solar Cells with a Green-Solvent Hole-Transport Layer. And the article contained the following:

Next-generation solution-processed solar cells will hopefully be processed using green solvents, and will unite high performance with operating stability. Colloidal quantum dot/polymer hybrid solar cells are of interest for their harvest of the visible as well as the near IR; however, today′s best polymer hole-transporting layers (HTLs) rely on processing using hazardous solvents such as chlorobenzene. This stems from the strong polymer-polymer attraction in polymeric p-type materials, which accounts for their limited solubility Here, a new random polymeric HTL (asy-ranPBTBDT) is reported that is soluble in green solvents such as 2-methylanisole without compromising ultimate device power conversion efficiency. The new polymer structure induces a strong π-π stacking face-on orientation and less lateral grain growth compared to control asy-PBTBDT, leading to reduced charge recombination and improved device stability. The resulting device exhibits a power conversion efficiency (PCE) of 13.2% and retains 89% of its initial efficiency after 120 h of continuous device operation at the maximum power point, compared to a PCE of 11.4% and 71% degradation for control devices.

In this article, we show that tribromide heterogenized on the surface of silica-coated magnetic nanoparticles modified with N2,N4,N6-tris(aminomethyl)-1,3,5-triazine-2,4,6-triamine [Fe3O4@SiO2-tris(triazine-triamine)-Br3] is a novel and efficient reusable nanocatalyst for the oxidation of sulfides to sulfoxides and oxidative coupling of thiols to disulfides using hydrogen peroxide as green oxidant. The structure of the as-fabricated Fe3O4@SiO2-tris(triazine-triamine)-Br3 was characterized by a series of spectroscopic techniques including FT-IR spectroscopy, SEM, TEM, EDX, VSM, XRD and TGA techniques. TEM and SEM anal. confirmed that the typical silica shell thickness was assessed to be around 20 nm. Recycling studies revealed that the Fe3O4@SiO2-tris(triazine-triamine)-Br3 could be easily recovered by a simple magnetic separation and recycled at least 6 times without deterioration in catalytic activity.

On December 1, 2021, Hyun Park, Sang; Su Jin, In; Woong Jung, Jae published an article.Application of 578-58-5 The title of the article was Green solvent engineering for environment-friendly fabrication of high-performance perovskite solar cells. And the article contained the following:

Antisolvent-assisted crystallization is a common process to fabricate high-performance perovskite solar cells (PSCs). At present, toxic organic solvents such as toluene or chlorobenzene have been used as typical antisolvents to fabricate compact perovskite absorber layer for a device, but their impact to environment or human/animal health has remained a challenge to be resolved for commercialization of PSCs. In this study, we suggest (R)-(+)-limonene and 2-methyltetrahydrofuran as eco-compatible and less-toxic antisolvents for preparing high-quality perovskite absorber layer in the inverted PSCs. The green antisolvents afford smooth, compact, less-defect, and full coverage perovskite films, comparable to the typical halogenated antisolvent-processed perovskite films, delivering a PCE up to 18.04% in CH3NH3PbI3-based device. The green antisolvent also demonstrated promising PCEs of 17.85%, 13.46%, and 10.04% in CH3NH3PbI3, CsPbI2Br, and BA2MA3Pb4I13-based PSCs accompanied with a halogen-free solvent-processed PC61BM layer. This work demonstrates a great potential of green antisolvents as a universal approach in obtaining high-quality perovskite films for fabricating high-efficiency PSCs.

And the article contained the following:

The design of efficient adsorbent with abundant binding sites for heavy metal ions is crucial for developing innovative materials that will remove pollutant metal ions. The high uptake capacity, kinetics, and affinity towards the toxic metals are the key requirements that the materials under invesigation should accomplish. Here we report the synthesis of iminodiacetic acid-functionalized hypercrosslinked polymer (IDA-HCP) for purification of water polluted by toxic metal ions via coordination of carboxylate and amino active sites on the surface of porous polymer. The obtained porous polymer is stable under harsh conditions and the structural features on the polymer work together to help the removal of Pb(II) with 1138 mg g-1 uptake capacity. In the meanwhile, the IDA-HCP reveals reuseability and very promising capture efficiency not only for Pb2+, but also for Hg2+ and Cd2+ from a mixture of Pb2+, Hg2+, Cd2+, Co2+, Fe3+, Zn2+, Mg2+, and Na+ metal ions. This result gives us confidence that the polymer material can solve the pollution problem caused by various metal ions.
