Star-shaped polymeric ionic liquids (PIL-3 and PIL-4) based on poly(2-(dimethyl-ethyl-amino)ethyl methacrylate) bis(trifluoromethylsulfonyl)imide (P(EtDMAEMA-TFSI)) with three-arm and four-arm architectures were prepared through atom transfer radical polymerization (ATRP) and ion exchange. Subsequently, gel polymer electrolytes (GPEs) comprising PIL host, N,N-diethyl-N-methyl-N-(2-methoxyethyl)ammonium bis(trifluoromethylsulfonyl)imide (DEME-TFSI) ionic liquid (IL) plasticizer with the same anion unit and LiTFSI salt were obtained. Compared with the linear PIL possessing the same elements, the increase of branches for PIL decreases the crystallity and glass transition temperature (Tg) of the corresponding GPEs. Accordingly, the ionic conductivity, electrochem. window and ion transport number of three-arm and four-arm PILs based GPEs (PIL-GPE-3 and PIL-GPE-4) are obviously superior to the linear contrastive sample. Among lithium metal batteries assembled by linear, three-arm and four-arm PILs based GPEs, Li/PIL-GPE-4/LiFePO4 presents the best performance. The specific discharge capacity attains 151 mAh g-1 at 0.1 C, the capacity retention ratio achieves 93.6% after 100 cycles at 60 °C, and the coulombic efficiency is around 99%. The outstanding compatibility between PIL-4 and IL and the resulted interfacial stability between PIL-GPE-4 and electrodes both contribute to the excellent performance.

He, Ying-Jie; Qin, Yan; Zhang, Tie-Li; Zhu, Yan-Yan; Wang, Zhao-Jie; Zhou, Zhong-Shun; Xie, Tian-Zhen; Luo, Xiao-Dong published the artcile< Migration of (non-) intentionally added substances and microplastics from microwavable plastic food containers>, Recommanded Product: 2,2′-(Tridecylazanediyl)diethanol, the main research area is microplastic microwavable toxic plastic food container migration; (Non-) intentionally added substances; High resolution mass spectrometry; Microplastics; Scanning electron microscopy.

Microwavable plastic food containers (MPFCs) are extensively used for food storage, cooking, rapid heating and as take-out containers. There is an urgent need to investigate whether MPFCs pose potential health risks, as a result of the migration of chems. into foods. Herein, 42 intentionally added substances (IAS) and > 100 non-IAS (NIAS) migrating from MPFCs were identified in food simulants according to Regulation (EU). The migration of major IAS and NIAS was higher in 95% ethanol compared to other simulants, and gradually decreased following repeated use. NIAS, including Cramer class III toxic compounds, such as PEG oligomers of N,N-bis(2-hydroxyethyl) alkyl(C8-C18)amines, isomers of hexadecanamide and oleamide, and Irgafos 168 OXO were detected and exceeded the recommended limits in some MPFCs. Furthermore, microplastics (MPs) were detected with high values of over one million particles/L in some MPFCs in a single test, and migration behaviors of MPs in different MPFCs were diverse. Surprisingly, this rigorous migration might result in an annual intake of IAS/NIAS up to 55.15 mg and 150 million MPs particles if take-out food was consumed once a day. Multi-safety evaluation studies on the migration of various chems. from MPFCs to foodstuffs during food preparation should be assessed.

The title compound [I, A = (CH2)2CO2H, B = (CH2)3Py, X = Cl; Py = 3-pyridyl] (II) and its analogs were synthesized and found to possess two activities, the inhibition of the biosynthesis of thromboxane A2 and antagonism of its receptors. Thus, II was prepared via arylsulfonylation of Et 6-amino-2-[(3-pyridinyl)propyl)]hexanoate, reduction, Wittig reaction with Ph3P:CHCO2Me, and treatment with NaBH4/CoCl2/MeOH. The in vitro and in vivo profile of these compounds as thromboxane receptor antagonists (TxRAs) and thromboxane synthase inhibitors (TxSls) is described.

The good bioavailability and the long duration of action of some of these compounds was demonstrated using ex vivo measurement of the TxRA and TxSl activities upon oral administration to guinea pigs. I [A = (CH2)2CO2H, B = (CH2)2OPy, X = Cl; A = SCH2CO2H, B = (CH2)3Py, X = Cl] and II potently inhibited arachidonic acid induced bronchoconstriction in guinea pigs.

Wright, Jay S.; Sharninghausen, Liam S.; Preshlock, Sean; Brooks, Allen F.; Sanford, Melanie S.; Scott, Peter J. H. published the artcile< Sequential Ir/Cu-Mediated Method for the Meta-Selective C-H Radiofluorination of (Hetero)Arenes>, Product Details of C13H19BO3, the main research area is sequential iridium copper mediated regioselective radiofluorination arene heteroarene.

This article describes a sequential Ir/Cu-mediated process for the meta-selective C-H radiofluorination of (hetero)arene substrates. In the first step, Ir-catalyzed C(sp2)-H borylation affords (hetero)aryl pinacolboronate (BPin) esters. The intermediate organoboronates are then directly subjected to copper-mediated radiofluorination with [18F]tetrabutylammonium fluoride to afford fluorine-18 labeled (hetero)arenes in high radiochem. yield and radiochem. purity. This entire process is performed on a bench top without Schlenk or glove box techniques and circumvents the need to isolate (hetero)aryl boronate esters. The reaction was automated on a TracerLab FXFN module with 1,3-dimethoxybenzene and a meta-tyrosine derivative The products, [18F]1-fluoro-3,5-dimethoxybenzene and an 18F-labeled meta-tyrosine derivative, were obtained in 37 ± 5% isolated radiochem. yield and >99% radiochem. purity and 25% isolated radiochem. yield and 99% radiochem. purity, and 0.52 Ci/μmol (19.24 GBq/μmol) molar activity (Am), resp.

Bam, Radha; Pollatos, Alexandros S.; Moser, Austin J.; West, Julian G. published the artcile< Mild olefin formation via bio-inspired vitamin B12 photocatalysis>, Recommanded Product: 4-(4-Methoxyphenyl)-1-butanol, the main research area is haloalkane cobalamin catalyst regioselective photochem dehydrohalogenation; alkene preparation; alkyl sulfonate cobalamin catalyst regioselective photochem olefination; olefin preparation.

A light-driven B12-based catalytic system that leverages this reactivity to convert alkyl electrophiles to olefins under incredibly mild conditions using only earth abundant elements was reported. Further, this process exhibited a high level of regioselectivity, producing terminal olefins in moderate to excellent yield and exceptional selectivity. Finally, it was able to access a hitherto-unknown transformation, remote elimination, using two cobalt catalysts in tandem to produce subterminal olefins with excellent regioselectivity. Together, vitamin B12 to be a powerful platform for developing mild olefin-forming reactions was showed.
