Significant advancements in C-N bond formationviaC-H bond functionalisation have made it a staple in the production of nitrogen-containing compounds in both industry and academia. However, transition metal-free synthesis, particularly in the case of C(sp(3))-N formation, has remained a significant challenge to the synthetic community. Herein we report a procedure for alpha-C(sp(3))-H amination of ethereal compounds through use of azodicarboxylates as the nitrogen source and freely-available atmospheric oxygen to access ethereal radical intermediatesviaaerobic C-H activation. The use of fluorinated alcohols as solvent is observed to greatly increase the efficiency of the reaction and we show experimentally and theoretically the key role of H-bonding between fluorinated alcohols and azodicarboxylates. Calculations of the condensed Fukui functions of a H-bonded fluorinated alcohol-azodicarboxylate complex correlates with a significantly increased susceptibility of azodicarboxylates to undergo reaction with radicals, which informs a number of recent reports in the literature.

In this paper, two level III fugacity models are developed and applied using an environmental system containing six compartments, including air, aerosols, soil, water, suspended particulate matters (SPMs), and sediments, as a unit world. The first model, assumes equilibrium between air and aerosols and between water and SPMs. These assumptions lead to a four-fugacity model. The second model removes these two assumptions leading to a six-fugacity model. The two models, compared using four PBDE congeners, BDE-28, -99, -153, and -209, with a steady flux of gaseous congeners entering the air, lead to the following conclusions. 1. When the octanol-air partition coefficient (K-OA) is less than 10(11.4), the two models produce similar results; when K-OA > 10(11.4), and especially when K-OA > 10(12.5), the model results diverge significantly. 2. Chemicals are in an imposed equilibrium in the four-fugacity model, but in a steady state and not necessary an equilibrium in the six-fugacity model, between air and aerosols. 3. The results from the six-fugacity model indicate an internally consistent system with chemicals in steady state in all six compartments, whereas the four-fugacity model presents an internally inconsistent system where chemicals are in equilibrium but not a steady state between air and aerosols. 4. Chemicals are mass balanced in air and aerosols predicted by the six-fugacity model but not by the four-fugacity model. If the mass balance in air and aerosols is achieved in the four-fugacity model, the condition of equilibrium between air and aerosols will be no longer valid. (C) 2021 Elsevier Ltd.

To investigate overall pollution and potential risk of 32 targets (11 PBDEs, 8 NBFRs, and 13 OPFRs) in indoor and outdoor environments, dust and PM10 samples were sampled from non-occupational and occupational zones in Chengdu, China. Sigma Cl-OPFRs, BDE-209, and DBDPE were the dominant constitutes in both the non occupational and occupational dust. Regarding the PM10, no significant differences were found between the kitchen and the living room for studied OPFRs except TDCIPP, and TCEP, TCPP, TEHP, and TCP displayed significant correlation among the kitchen, the living room and personal samples. Profiles of the OPFRs in the PM10 from occupational areas presented great variation and ranked as: Sigma Aryl-OPFRs < Sigma Alkyl-OPFRs < Sigma Cl-OPFRs. The estimated daily intakes (EDIs) of the investigated FRs via dust suggested dust ingestion and inhalation were the main exposure route to FRs, and the total of EDIs were at least one order of magnitude lower than reference data, indicating a low risk for the general public in Chengdu. However, with increasing usage of FRs in daily goods, a long-term monitoring should be conducted.

Background: Neurotoxic effects of Polybrominated Diphenyl Ethers (PBDEs) at low levels have not been well studied in human population, and whether the associations can be explained by thyroid hormones (THs) remains unclear. Objectives: We examined the associations of prenatal PBDE exposures with THs in cord plasma and neurobehavior of children at 2 and 4 years among general population in China. Methods: Participants were mother-child pairs in the Shanghai-Minhang Birth Cohort Study. Nine PBDE congeners and THs (thyroid stimulating hormone, total thyroxine, free thyroxine, total triiodothyronine, and free triiodothyronine) were determined in cord plasma. Child Behavior Checklist (CBCL/1.5-5) were completed by caregivers to assess children’s neurobehavioral development at 2 and 4 years. In the final analyses, 199 and 307 mother-child pairs at 2 and 4 years were included to examine associations of PBDEs with CBCL scores using Pearson-scale-adjusted Poisson regressions, and 339 subjects were included in linear regression models to investigate the associations between PBDEs and THs. Results: BDE-47 had the highest detection rate of 83.82% with the median concentration of 0.19 ng/g lipid, followed by BDE-28, -99, -100 and -153 with detection rates nearly 50%. We found positive associations between prenatal PBDE concentrations and children’s neurobehavior, including Somatic Complaints, Withdrawn, Sleep Problems and Internalizing Problems in girls, and Somatic Complaints and Attention Problems in boys. We also observed inverse associations of the sum of BDE-47, – 28, – 99, -100 and -153 with THs. However, by adding THs to the models examining associations between PBDEs and CBCL, the main results didn’t measurably change. Conclusions: This study adds new knowledge that prenatal PBDEs at low levels may be related to long-lasting behavioral abnormalities in children and reduced THs in cord plasma. However, the hypothesis that the neurotoxic impact of PBDEs may be explained by alterations in cord THs was not supported.

Safety of Diphenyl oxide. I found the field of Environmental Sciences & Ecology very interesting. Saw the article A new marine sediment certified reference material (CRM) for the determination of persistent organic contaminants: IAEA-459 published in 2019, Reprint Addresses Tolosa, I (corresponding author), IAEA Environm Labs, 4a Quai Antoine 1Er, MC-98000 Monaco, Monaco.. The CAS is 101-84-8. Through research, I have a further understanding and discovery of Diphenyl oxide.

A new marine sediment certified reference material (IAEA 459) with very low concentrations (gkg(-1)) for a variety of persistent organic contaminants (POPs) listed by the Stockholm Convention, as well as other POPs and priority substances (PSs) listed in many environmental monitoring programs was developed by the IAEA. The sediment material was collected from the Ham River estuary in South Korea, and the assigned final values were derived from robust statistics on the results provided by selected laboratories which demonstrated technical and quality competence, following the guidance given in ISO Guide 35. The robust mean of the laboratory means was assigned as certified values, for those compounds where the assigned value was derived from at least five datasets and its relative expanded uncertainty was less than 40% of the assigned value (most of the values ranging from 8 to 20%). All the datasets were derived from at least two different analytical techniques which have allowed the assignment of certified concentrations for 22 polychlorinated biphenyl (PCB) congeners, 6 organochlorinated (OC) pesticides, 5 polybrominated diphenyl ethers (PBDEs), and 18 polycyclic aromatic hydrocarbon (PAHs). Mass fractions of compounds that did not fulfill the criteria of certification are considered information values, which include 29 PAHs, 11 PCBs, 16 OC pesticides, and 5 PBDEs. The extensive characterization and associated uncertainties at concentration levels close to the marine sediment quality guidelines will make CRM 459 a valuable matrix reference material for use in marine environmental monitoring programs.

Formula: C12H10O. The Name is Diphenyl oxide. Through research, I have a further understanding and discovery of 101-84-8.

Methods for direct C-H trifluoromethoxylation of arenes and heteroarenes are rare, despite the importance of trifluoromethoxylated compounds for pharmaceuticals, agrochemicals, and material sciences. Especially selective C-H trifluoromethoxylation of pyridines remains a formidable challenge. Here we show a general late-stage C-H trifluoromethoxylation of arenes and heteroarenes as limiting reagent with trifluoromethoxide anion. The reaction is mediated by silver salts under mild reaction conditions, exhibiting broad substrate scope and wide functional-group compatibility. In addition, ortho-position selective C-H trifluoromethoxylation of pyridines is observed. The method is not only applicable to the gram-scale synthesis of trifluoromethoxylated products but also allows efficient late-stage C-H trifluoromethoxylation of marketed small-molecule drugs, common pharmacophores and natural products. Selective C-H trifluoromethoxylation of pyridines remains a formidable synthetic challenge. Here, the authors report a silver-mediated late-stage C-H trifluoromethoxylation of arenes and heteroarenes as limiting reagents with trifluoromethoxide anion.

Casein kinase II (CK2) is an intensively studied enzyme, involved in different diseases, cancer in particular. Different scaffolds were used to develop inhibitors of this enzyme. Here, we report on the synthesis and biological evaluation of twenty phenolic, ketonic, and para-quinonic indeno[1,2-b]indole derivatives as CK2 inhibitors. The most active compounds were 5-isopropyl-1-methyl-5,6,7,8-tetrahydroindeno[1,2-b]indole-9,10-dione 4h and 1,3-dibromo-5-isopropyl-5,6,7,8-tetrahydroindeno[1,2-b]indole-9,10-dione 4w with identical IC50 values of 0.11 mu M. Furthermore, the development of a QSAR model based on the structure of indeno[1,2-b]indoles was performed. This model was used to predict the activity of 25 compounds with naphtho[2,3-b]furan-4,9-dione derivatives, which were previously predicted as CK2 inhibitors via a molecular modeling approach. The activities of four naphtho[2,3-b]furan-4,9-dione derivatives were determined in vitro and one of them (N-isopentyl-2-methyl-4,9-dioxo-4,9-dihydronaphtho[2,3-b]furan-3-carboxamide) turned out to inhibit CK2 with an IC50 value of 2.33 mu M. All four candidates were able to reduce the cell viability by more than 60% after 24 h of incubation using 10 mu M.

COA of Formula: C12H10O. The Name is Diphenyl oxide. Through research, I have a further understanding and discovery of 101-84-8

Two new compounds, named penisclerotiorin A (1) and diaporthein C (8), and a new natural product, penidepsidone A (4), together with five known compounds (2, 3, 5-7) were isolated from the fungus Penicillium sclerotiorum GZU-XW03-2. Their structures were assigned using spectroscopic methods, quantum chemical calculations, and single-crystal X-ray diffraction analysis. Penisclerotiorin A (1) that belongs to the highly oxidized diphenyl ether is rare found in natural sources, and it was the sixth example of highly oxidized diphenyl ether analogues in natural sources. Penidepsidone A (4) is a new natural product and no any NMR spectral data were reported to date, in this paper, we firstly used the NMR calculations to confirm the intact structure by comparison of the experimental NMR data. Diaporthein C (8) represents the third example of pimarane diterpenes bearing a double bond at C-8 and C-9. In the bioassays, all of the isolates (1-8) were tested for their anti-inflammatory effects on the production of nitric oxide in lipopolysaccharide-induced microglial cells (RAW 264.7 cells). Compounds 2, 3 and 6 showed potent anti-inflammatory effects than the positive control (indomethacin, IC50, 24.0 mu M) with IC50 values of 11.52, 8.13 and 21.27 mu M, respectively.

In this paper, a novel approach to regioselective alpha- or gamma-hydroarylation of 3-allylchromones with electron-rich arenes has been presented. Results of this study indicated that the regioselectivity was dependent on the substituent at the gamma-position of the allyl group. Hydrogen or alkyl substitution favored alpha-hydroarylation, whereas aryl substitution favored gamma-hydroarylation. This methodology provides an efficient means to achieve the alpha- or gamma-selective hydroarylation of 3-allylchromones. Application of alpha-hydroarylation to perform Pd-catalyzed one-pot sequential alpha-hydroarylation and pi-chelation-assisted olefination has also been reported.

Iron-based metal-organic framework VNU-20 was utilized as a heterogeneous catalyst for cascade reactions between ketoximes and dibenzyl ether to produce 2,4,6-triphenylpyridines. Additionally, benzyl alcohol and (dimethoxymethyl) benzene could be used as an alternative starting materials for the transformation. The oxidant exhibited a remarkable impact on the reactions, and di-tertbutylperoxide was the most appropriate candidate. The VNU-20 displayed higher efficiency than many homogeneous and heterogeneous catalysts. The catalyst was reusable for the cascade reactions without a noticeable deterioration in catalytic activity. This transformation is new, and would offer alternative routes to triphenylpyridines utilizing ketoximes as building blocks.
