Ionic liquid-multi-walled carbon nanotubes modified screen-printed electrodes for sensitive electrochemical sensing of uranium

Here, two screen-printed electrodes modified with multi-walled carbon nanotubes alone (electrode III) or along with a triazole-based ionic liquid (electrode VII) were developed for sensitive uranium(VI) determination. The electrodes exhibited calibration slopes of 25.10 +/- 1.35 and 29.93 +/- 0.88 mV decade(-1) over the concentration ranges of 1.0 x 10(-5)-1.0 x 10(-1) and 4.7 x 10(-7)-1.0 x 10(-1) mol L-1 for electrodes III and VII, respectively. The electrodes showed fast response times with a service life exceeding 5 months. The electrodes revealed good thermal stability and fairly high uranium(VI) selectivity over many cations and anions. The electrodes were successfully employed for sensitive detection of uranium(VI) in different water samples.

[N-N=N-N]-linked fused triazoles with pi-pi stacking and hydrogen bonds: Towards thermally stable, Insensitive, and highly energetic materials

It is the main task and challenge to reach a fine balance between high energy density and good molecular stability in energetic material research. In this study, two series of energetic compounds, 3-amino-7,7′-azo-[1,2,4] triazolo[4,3-b][1,2,4]triazole and 3,6-diamino-7,7′-azo-[1,2,4]triazolo[4,3-b][1,2,4] triazole featuring the N-4 [N-N=N-N] linkage and fused triazoles, are presented. Their structures were determined by single crystal X-ray diffraction, elemental analysis, NMR, and IR spectroscopy. Their properties were studied in terms of density, thermal stability, detonation performance, and mechanical sensitivity. The N-4 [N-N=N-N] linkages accord these compounds with high heat of formation, thus increasing the detonation performance. All fused triazoles exhibit planar structures, which result in low mechanical sensitivity. Through careful investigation of crystal data, strong pi-pi stacking and extensive hydrogen-bonding interactions were observed between molecules, which gives positive impact on mechanical sensitivity and thermal stability. The properties between different cations (or ions) were carefully studied. Quantum chemistry calculations were performed to investigate the potential relationship between structures and properties. Among them, compound 5 possesses high thermal stability (T-d: 275 degrees C), good detonation performance (D: 8677 m s(-1); P: 36.1 GPa), and excellent insensitivity (IS: 40 J; FS: 360 N), which makes it a balanced and promising energetic material.

Transition-metal-free synthesis of 5-amino-1,2,3-triazoles via nucleophilic addition/cyclization of carbodiimides with diazo compounds

A simple and transition-metal-free strategy to construct 5-amino-1,2,3-triazoles using carbodiimides and diazo compounds has been developed. This protocol involves a cascade nucleophilic addition/cyclization process and is accomplished under mild conditions. Further functionalization enriched the molecular diversity of triazoles. Control experiments and DFT calculations clarify the reaction mechanism and rationalize the kinetic and thermodynamic selectivity observed in the transformation. The late-stage derivatization and gram-scale synthesis reveal the promising utility of this methodology.

Haloalkenyl Imidoyl Halides as Multifacial Substrates in the Stereoselective Synthesis of N-Alkenyl Compounds

N-Alkenyl compounds are versatile synthetic building blocks and their stereoselective transformations are key processes in the synthesis of many prominent classes of natural products, pharmaceuticals, and agrochemicals. However, a large structural variety of known N-alkenyl compounds and their diverse reactivity have so far precluded the development of a general method for their stereoselective synthesis. Herein we present an aluminum halide-mediated, highly stereoselective, efficient and scalable transformation of commercially available N-fluoroalkyl-1,2,3-triazoles to N-haloalkenyl imidoyl halides, and demonstrate their use in the synthesis of stereodefined N-alkenyl amides, amidines, imines, hydrazonoamides, imidothioates, iminophosphonates, 1,2,4-triazoles and tetrazoles. The reaction is of wide scope on both the triazole substrate and aluminum halide, providing highly functionalized products. Mechanistic and computational investigations suggest a reaction mechanism involving the triazole ring opening, initiated by the coordination of nitrogen one of the triazole ring to the Lewis acid, N-2 elimination and the formation of a vinyl cation intermediate, which reacts with nitrogen-bound aluminum halide, followed by a series of halide exchange reactions on C-X and Al-X bonds.

Synthesis of biologically important 4-Phenyl-C-glycosyl-1,2,3-triazole derivatives by Cu(I)-catalyzed azide-alkyne cycloaddition

A new series of 4-phenyl-C-glycosyl-1,2,3-triazoles were synthesized using Cu(I)- catalyzed azide-alkyne cycloaddition. The key step in the synthesis involved the coupling of unprotected glycosyl azides with substituted C-glycosylated phenyl acetylenes. Using o-phenylenediamine as a ligand, we could significantly reduce the reaction time, improve the product yield, and simplify the purification process. Broad substrate scope in terms of sugars was achieved.

A Facile Total Synthesis of Mubritinib

A five-step, practical, and concise total synthesis of mubritinib is described. The synthesis utilized Friedel-Crafts acylation, click reaction, reduction, and demethylation for the construction of the triazole ring system as key steps. Another important feature of this synthesis is the Bredereck oxazole synthesis. The main advantages of this process are the improved yield and decreased number of reaction steps, which paves the way for the industrial-scale synthesis of mubritinib.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 381-98-6 is helpful to your research. Computed Properties of C4H3F3O2.

Exposure to fungicide difenoconazole reduces the soil bacterial community diversity and the co-occurrence network complexity

Difenoconazole is a triazole fungicide that is widely used worldwide and has been frequently detected in agricultural soils, but its ecotoxicological effect on soil bacterial community remains unknown. Here, the degradation of difenoconazole and its effect on soil bacterial communities were investigated at three concentrations in five different agricultural soils. Difenoconazole degraded faster in non-sterilized soils than in sterilized soils, suggesting that biodegradation is a major contributor to the dissipation of difenoconazole in soils. Exposure to high concentrations of difenoconazole decreased the soil bacterial community diversity in most soils, and this influence was aggravated with the increasing concentration. The effect of difenoconazole on soil bacterial community diversity was also enhanced with the increasing content of organic matter and total nitrogen in soils. Moreover, difenoconazole exposure also reduced the soil bacterial community network complexity and exhibited a concentration-dependent characteristic. In addition, a core bacterial community (57 operational taxonomic units, OTUs) was identified, and some core OTUs were strongly linked to the degradation of difenoconazole in soils. It is concluded that high concentrations of difenoconazole may have a significant effect on the soil bacterial communities, and co-occurrence networks may improve the ecotoxicological risk assessment of fungicides on soil microbiome.

Synthesis, in silico ADME, molecular docking and in vitro cytotoxicity evaluation of stilbene linked 1,2,3-triazoles

Series of (E)-1-benzyl-4-((4-styrylphenoxy)methyl)-1H-1,2,3-triazoles 7a-x were obtained by Wittig reaction between 4-((1-benzyl-1H-1,2,3-triazol-4-yl)methoxy)benzaldehydes 5a-d and benzyl triphenyl phosphonium halides 6a-f in benzene. The structures of the synthesized compounds were confirmed by FTIR, NMR (H-1 and C-13 NMR)spectroscopy, and mass spectrometry. All synthesized compounds were screened for their cytotoxic activity against human cancer cell lines including pancreatic carcinoma, colorectal carcinoma, lung carcinoma, and leukemias such as acute lymphoblastic, chronic myeloid, and non-Hodgkinson lymphoma cell lines. In vitro cytotoxicity data showed that compounds 7c, 7e, 7h, 7j, 7k, 7r, and 7w were moderately cytotoxic (11.6 -19.3 mu M) against the selected cancer cell lines. These cytotoxicity findings were supported using molecular docking studies of the compounds against 1TUB receptor. The drug-likeness properties of the compounds evaluated by in silico ADME analyses. Resveratrol linked 1,2,3-triazoles were more sensitive towards human carcinoma cell lines but least sensitive towards leukemia and lymphoma cell lines.
