Precise control over the morphology and size of coordination polymers (CPs) is crucial for extending these inorganic-organic materials to many advanced applications, in particular for heterogeneous catalysis. In this work, two Zn-based CPs, {[Zn-3(idbt)(2)(4,4 ‘-dmbpy)(2)]center dot H2O}(n) (1) and {[Zn-3(idbt)(2)(H2O)(3)]center dot H2O}(n) (2) (H(3)idbt = 5,5 ‘-(1H-imidazole-4,5-diyl)-bis-(2H-tetrazole), 4,4 ‘-dmbpy = 4,4 ”-dimethyl-2,2 ‘-bipyridine), were synthesized through solvothermal reactions. The morphologies and particle sizes of 1 and 2 could be controlled from large scale to nanoscale by regulating the amount of poly(vinyl alcohol) (PVA). Furthermore, for the conversion reactions of nitromethylbenzenes into benzoic acids, the catalytic properties of nanoscale 1 and 2 were much more efficient than those of large size of 1 and 2, because of the benefit of readily accessible active sites in the nanoscale sized particles, which provide a tunable and functionalizable platform for the conversion reaction by minimizing the diffusion distance but do little for the selectivity.

New 2,5-bis(azacyclohex-1-yl)-8-nitro-1,3-benzothiazin-4-ones were synthesized from 2,6-difluorobenzoic acid in two preparative stages. The ethoxycarbonylpiperazino derivative surpasses in tuberculostatic activity (MIC 4 mu g ml(-1)) its 5-fluoro-8-H-counterpart. The first representative of 5-fluoro-8-nitro-1,3-benzothiazin-4-ones was obtained through the condensation of 2,6-difluoro-3-nitrobenzoyl isothiocyanate and N-methylindole.

Transition-metal-catalyzed sp(2) C-N bond formation is a reliable method for the synthesis of aryl amines. Catalytic sp(3) C-N formation reactions have been reported occasionally, and methods that can realize both sp(2) and sp(3) C-N formation are relatively unexplored. Herein, we address this challenge with a method of catalytic decarboxylative C-N formation that proceeds through a cascade carboxylic acid activation, acyl azide formation, Curtius rearrangement and nucleophilic addition reaction. The reaction uses naturally abundant organic carboxylic acids as carbon sources, readily prepared azidoformates as the nitrogen sources, and 4-dimethylaminopyridine (DMAP) and Cu(OAc)(2) as catalysts with as low as 0.1 mol % loading, providing protected alkyl, alkenyl and aryl amines in high yields with gaseous N-2 and CO2 as the only byproducts. Examples are demonstrated of the late-stage functionalization of natural products and drug molecules, stereospecific synthesis of useful alpha-chiral alkyl amines, and rapid construction of different ureas and primary amines.

This report describes a palladium-catalyzed decarboxylative aryl allylation between unactivated benzoic acids and allylic carbonates. This transformation successfully couples a variety of carbonates and benzoic acids in good yield (up to 94%) using 1 mol% palladium. This salt free allyl-arylation proceeds without added base, copper, or silver. The only stoichiometric byproducts are carbon dioxide and tert-butanol.

The novel coronavirus disease COVID-19 that emerged in 2019 is caused by the virus SARS CoV-2 and named for its close genetic similarity to SARS CoV-1 that caused severe acute respiratory syndrome (SARS) in 2002. Both SARS coronavirus genomes encode two overlapping large polyproteins, which are cleaved at specific sites by a 3C-like cysteine protease (3CL(pro)) in a post-translational processing step that is critical for coronavirus replication. The 3CL(pro) sequences for CoV-1 and CoV-2 viruses are 100% identical in the catalytic domain that carries out protein cleavage. A research effort that focused on the discovery of reversible and irreversible ketone-based inhibitors of SARS CoV-1 3CL(pro) employing ligand-protease structures solved by X-ray crystallography led to the identification of 3 and 4. Preclinical experiments reveal 4 (PF-00835231) as a potent inhibitor of CoV-2 3CL(pro) with suitable pharmaceutical properties to warrant further development as an intravenous treatment for COVID-19.

Diflubenzuron (DFB) and fenuron (FEN) are benzoylurea and phenylurea pesticides, widely used in Senegal, that do not exhibit any natural fluorescence, but can be determined by means of photoinduced fluorescence (PIF) methods. Photodegradation of DFB and FEN yielded a number of fluorescent and non-fluorescent photoproducts. For both pesticides, at least 10 photoproducts were detected and identified by gas chromatography-mass spectrometry (GC/MS). To identify the formed fluorescent DFB and FEN photoproducts, their fluorescence spectra were compared with those of standard compounds, including phenol and p-hydroxyaniline.

Totally colorless, transparent, and highly refractive poly(phenylene thioether ether)s (PPTEs) containing thianthrene-2,7-disulfanyl moiety were developed in this study. A new 4,4′-diol aromatic compound, 2,7-(4,4′-diphenol)thiothianthrene (DPTT), with a high sulfur content was designed and synthesized to develop polymers with high refractive indices and high thermal stabilities. The PPTEs were prepared by polycondensation of DPTT with organic dihalogen compounds, such as 2,6-difluorobenzonitrile (DFBN) and 4,6-dichloro-2-(methylthio) pyrimidine (DCMP). The obtained polymers showed good thermal stabilities such as relatively high glass transition temperatures (T(g)s) in the range of 153-176 degrees C and 5% weight loss temperatures (T-5%) over 344 degrees C. The cut-off wavelengths (lambda(0)) of the PPTE films are shorter than 343 nm, and they have a transmittance higher than 93% at 550 nm. The combination of the pyrimidine and high sulfur-containing thianthrene derivatives provides the PPTEs with a high refractive index of 1.7204 and a small birefringence of 0.0106 at 637 nm.

This report details a decarboxylative cross-coupling of (hetero)aryl carboxylates with iodoarenes in the presence of a gold catalyst (>25 examples, up to 96% yield). This reaction is site specific, which overcomes prior limitations associated with gold catalyzed oxidative coupling reactions. The reactivity of the (hetero)aryl carboxylate correlates qualitatively to the field effect parameter (F-ortho). Reactions with isolated gold complexes and DFT calculations support a mechanism proceeding through oxidative addition at a gold(I) cation with decarboxylation being viable at either a gold(I) or a silver(I) species.

Etoxazole is a newly registered and widely used acaricide. However, its metabolites were not fully understood and might exhibit similar or even higher toxicity than parent compound. Therefore, in this study, the metabolites of etoxazole in citrus, soil and earthworms were firstly identified by an ultra-performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry (UPLC-QTOF/MS). Four potential metabolites in citrus, 11 in soil, and 8 in earthworms were determined. These metabolites were then further structural elucidated based on the fragment pathways, and accurate mass measurement. The distributions of etoxazole and its main metabolites (M1, M2, M3, M4 and M5) which were identified as the dehydrogenation, hydrolysis, oxidation products of etoxazole (M0) were also monitored in citrus, soil and earthworms at different exposure periods. The 45 days exposure experiment showed that M0 gradually decreased in citrus and soil samples by 80% and 28% of the initial amounts, respectively. In earthworm samples, M0 accumulated in the bodies of the worms during 24 days exposure and then decreased with time. The dissipation rate of etoxazole were citrus > earthworms > soil. Concentrations of M1 and M3 in soil were found continuously increased with time during the experimental period. Moreover, the persistence of M1 in earthworm samples was also observed. Great attention should be paid to these two compounds due to their potential risks to both environmental and human health. (C) 2019 Published by Elsevier Ltd.
