The quality of the Dniester River Basin has been seriously impacted by the chemicals released by agriculture, industry, and wastewater discharges. To assess its current chemical pollution status, a transboundary monitoring campaign was conducted in May 2019. Thirteen surface water, 13 sediment, and three biota samples were collected and analyzed using generic sample preparation methods for the determination of organic substances by liquid chromatography high-resolution mass spectrometry (LC-HRMS) and metals by inductively coupled plasma mass spectrometry (ICP-MS). Wide-scope target and suspect screening resulted in detection of Water Framework Directive (WFD) priority substances and emerging contaminants, whereas the raw data were stored in NORMAN Digital Sample Freezing Platform (DSFP) for future retrospective screening. Furthermore, risk assessment was performed to prioritize detected substances and propose a draft list of river basin-specific pollutants. All studied metals (As, Hg, Zn, Cu, Cr, Cd, Pb, Ni) were detected in the surface water and sediments. In total, 139 organic contaminants belonging to various chemical classes (pesticides, pharmaceuticals, drugs of abuse, stimulants, sweeteners, industrial chemicals, and their transformation products) were detected. The highest cumulative concentration of contaminants was observed in surface water from the Byk River, a tributary of the Dniester (Moldova). Concentrations of WFD priority substances diuron and mercury and EU Watch List neonicotinoid compounds imidacloprid and thiamethoxam exceeded their environmental quality standards (EQS), whereas concentrations of 23 emerging substances exceeded their predicted no-effect concentration (PNEC) at minimum one site. Emerging contaminants telmisartan, metolachlor, terbuthylazine, and 4-acetamidoantipyrine were prioritized as potential river basin-specific pollutants. Graphical abstract

A novel one-pot approach for the synthesis of trichloroacetates is described. Use of inexpensive, commercially available trichloroacetonitrile as a trichloroacyl source has made this protocol have more industrial applications. This one-pot approach is applicable to a wide range of alcohols as demonstrated by 28 examples with good to excellent yields in the order of 93%. Trichloroacetates were characterized by infrared, NMR spectra and further the structure of 2-(1,3-dioxoisoindolin-2-yl)ethyl-2,2,2-trichloroacetate was confirmed by single-crystal X-ray diffraction. Moreover, benzyl trichloroacetates synthesized were converted into corresponding benzyl iodides in good yields (51-70%). In addition, bypassing harsh reagents, use of cheaper, commercially available sodium iodide as nucleophile and mild reaction conditions are some of practical features of this methodology.

Selective monoamine oxidase B inhibitors are potential drug candidates for the treatment of Parkinson’s disease. A series of phenyl substituted isoxazole carbohydrazides was designed by structural modification of isocarboxazid, a nonselective MAO inhibitor and evaluated as inhibitors of MAO-A and MAO-B. The compounds were not able to inhibit MAO-A significantly, but most of the compounds exhibited potent inhibitory activity against MAO-B. The enzyme kinetic study of the most active compounds 5d, 5-phenyl-N ‘-(1-(p-tolyl)ethylidene)isoxazole-3-carbohydrazide and 5g, N ‘-(1-(3,4-dimethoxyphenyl)ethylidene)-5-phenylisoxazole-3-carbohydrazide displayed reversible and competitive MAO-B inhibition. In molecular modeling studies, compounds 5d and 5g exhibited strong binding affinity on MAO-B active site. The administration of compounds 5d and 5g exhibited prevention of MPTP-induced Parkinsonism as indicated by footprint analysis and horizontal wire tests. Further optimization studies are essential to exploit their potential for MAO-B associated neurodegenerative pathologies.

Herein, we report a multi-residue method based on dissolution-precipitation extraction combined with gas chromatography-tandem mass spectrometry (GC-MS/MS) analysis for targeted screening and quantification of 216 harmful chemicals in plastic children’s toys. We established a spectrogram database containing the first-order mass spectra of all analytes and their second-order mass spectra at different collision energies. Good separation was attained in less than 60 min. As a simple and low-cost extraction method, dissolution-precipitation exhibited good recoveries for the analytes in the plastic samples. The matrix-matched standard curves were accurate for analyte quantification in specific plastics due to the solvent effects and matrix effects. The limits of quantification range were 0.1 mg/kg to 10 mg/kg. A wide linear range of 0.1-200 mg/kg was also observed, with r(2)>= 0.9924. The average recoveries ranged from 63.9% to 137.6%, and the relative standard deviation (n = 6) varied from 0.6% to 13.2%. Finally, 31 ABS actual toys and 30 PVC actual toys were detected and 20 analytes with contents ranging from 0.4 mg/kg to 172 mg/kg and 30 analytes from 0.8 mg/kg to 141,030 mg/kg were discovered respectively.

Highly active natural pandanus-extracted cellulose-supported poly(hydroxamic acid)-Cu(II) complex 4 was synthesized. The surface of pandanus cellulose was modified through graft copolymerization using purified methyl acrylate as a monomer. Then, copolymer methyl acrylate was converted into a bidentate chelating ligand poly(hydroxamic acid) via a Loosen rearrangement in the presence of an aqueous solution of hydroxylamine. Finally, copper species were incorporated into poly(hydroxamic acid) via the adsorption process. Cu(II) complex 4 was fully characterized by Fourier transform infrared (FTIR), field emission scanning electron microscopy (FE-SEM), energy-dispersive X-ray (EDX), transmission electron microscopy (TEM), inductively coupled plasma optical emission spectrometry (ICP-OES), thermogravimetric analysis (TGA), X-ray diffraction (XRD), and X-ray photoelectron spectroscopy (XPS) analyses. The cellulose-supported Cu(II) complex 4 was successfully applied (0.005 mol %) to the Ullmann etherification of aryl, benzyl halides, and phenacyl bromide with a number of aromatic phenols to provide the corresponding ethers with excellent yield [benzyl halide (70-99%); aryl halide (20-90%)]. Cu(II) complex 4 showed high stability and was easily recovered from the reaction mixture. It could be reused up to seven times without loss of its original catalytic activity. Therefore, Cu(II) complex 4 can be commercially utilized for the preparation of various ethers, and this synthetic technique could be a part in the synthesis of natural products and medicinal compounds.

Direct oxidative coupling of different inert C-H bonds is the most straightforward and environmentally benign method to construct C-C bonds. In this paper, we developed a Pd-catalyzed intramolecular oxidative coupling between unactivated aliphatic and aryl C-H bonds. This chemistry showed great potential to build up fused cyclic scaffolds from linear substrates through oxidative couplings. Privileged chromane and tetralin scaffolds were constructed from readily available linear starting materials in the absence of any organohalides and organometallic partners.

Schiff base Cu(II), Co(II), Ni(II), Cr(III) and Fe(III) complexes have been synthesized via the reaction of the 2-amino-3-hydroxy-4-bromopyridine with 2-chloro-5-nitrobenzaldehyde and different transition metal salts. The complexes have been characterized by several methods. In addition, the prepared complexes were tested as precursors for the synthesis of their corresponding metal oxides nanoparticles by controlled aerobic thermal decomposition at 500 degrees C. The structure, composition, morphology and particle size of the prepared nanostructured metal oxides were characterized by FTIR, X-ray powder diffraction and by scanning and transmission electron microscopy. In addition, the corresponding materials have been tested as catalysts in the heterogeneous selective solvent free oxidation of benzyl alcohol giving high selectivities to benzaldehyde. In addition, the nanostructured metal oxides gave, in general, higher conversions than those of the starting Schiff base metal complexes. Finally, the nanostructured metal oxides have been treated with an organometallic Pd(II) precursor to prepare Pd-doped metal oxides, which have been tested as catalysts in two different C-C coupling reactions, namely, the coupling reaction between iodobenzene and phenylboronic acid and the double coupling of iodobenzene with 2,6-dibromopyridin. In all cases interesting conversions and yields were observed for the nanostructured metal oxides. Graphic
