A series of new sulfone compounds containing the 1,3,4-oxadiazole moiety were designed and synthesized. Their structures identified by 1H 13C nuclear magnetic resonance elemental analyses. Antibacterial bioassays indicated that most exhibited promising in vitro antibacterial bioactivities against tobacco bacterial wilt at 200 μg/mL. The relationship between structure activity was also discussed. Among title compounds, 5′c, 5′h, 5′i, 5′j could inhibit mycelia growth Ralstonia solanacearum...
The distinctive properties of hexagonal and cubic CdS illuminate their electronic, optical, structural features, with practical implications explored through applications in various fields.
Starting from 4-chlorobenzoic acid, 10 new 5-(4-chlorophenyl)-N-substituted-N-1,3,4-thiadiazole-2-sulfonamide derivatives were synthesized in six-steps. Esterification of acid with methanol and subsequent hydrazination, salt formation cyclization afforded 5-(4-chlorophen-yl)-1,3,4-thiadiazole-2-thiol (5). Conversion this intermediate into sulfonyl chloride 6, followed by nucleophilic attack the amines gave title sulfonamides 7a-7j whose structures confirmed NMR, IR elemental analysis. The...
A series of new sulfone compounds containing 1,3,4-oxadiazole moieties were synthesized. The structures these confirmed by spectroscopic data (IR, ¹H- and ¹³C-NMR) elemental analyses. Antifungal tests indicated that all the title exhibited good antifungal activities against eight kinds plant pathogenic fungi, some showed superiority over commercial fungicide hymexazol. Among them, 5d, 5e, 5f, 5i prominent activity B. cinerea, with determined EC₅₀ values 5.21 μg/mL, 8.25 µg/mL, 8.03 21.00...
A series of sulfone derivatives containing 1, 3, 4-oxadiazole moiety were prepared and evaluated for their antibacterial activities by the turbidimeter test. Most compounds inhibited growth Ralstonia solanacearum (R. solanacearum) from tomato tobacco bacterial wilt with high potency, among which 5a 5b exhibited most potent inhibition against R. wilts EC50 values 19.77 8.29 μg/mL, respectively. Our results also demonstrated that 5a, 5b, a number other more than commercial bactericides Kocide...
Deficient catalytic sensitivity to the tumor microenvironment is a major obstacle nanozyme-mediated therapy. Electron transfer intrinsic essence for nanozyme-catalyzed redox reaction. Here, we developed nanohole-array-induced metallic molybdenum selenide (n-MoSe2) that enriched with Se vacancies and can serve as an electronic station cycling electrons between H2O2 decomposition glutathione (GSH) depletion. In MoSe2 nanohole array, phase reaches up 84.5%, which has been experimentally...
Comprehensive x-ray powder diffraction studies were carried out in magnetite the 80--150 K and 0--12 GPa ranges with a membrane-driven diamond anvil cell helium as pressure medium. Careful data analyses have shown that reversible, cubic to distorted-cubic, structural transition takes place increasing pressure, within ($P,T$) regime below Verwey temperature ${T}_{V}(P)$. The experimental documentation ${T}_{V}(P)={T}_{\mathrm{dist}}(P)$ implies pressure-temperature-driven metal-insulator is...
Under high pressures the hydrogen bonds were predicted to transform from a highly asymmetric soft O-H···O symmetric rigid configuration in which proton lies midway between two oxygen atoms. Despite four decades of research on hydroxyl containing compounds, pressure induced bond symmetrization remains elusive. Following single crystal x-ray diffraction, Mössbauer and Raman spectroscopy measurements supported by ab initio calculations, we report H-bonds iron oxyhydroxide, FeOOH, resulting...
Mesoporous silica-supported spinel phase CuCo2O4 mixed-metal oxide nanoparticles were synthesized as a catalyst for the selective oxidation of substituted benzyl alcohols to aromatic aldehydes, in which oxygen gas was used an oxidant. It possessed high catalytic activity, achieving nearly 100% conversion 8 h, much higher than mesoporous CuO nanoparticles, Co3O4 and their mixtures, demonstrating advantage mixed metal due its unique electronic states. The enhanced activity may come from...
The design and fabrication of layered transition metal chalcogenides with high exposure crystal layer edges is one the key paths to achieve distinctive performances in their catalysis electrochemistry applications. Two-dimensional WSe2 MoSe2 nanomeshes orderly arranged nanoholes were synthesized by using a mesoporous silica material KIT-6 three-dimensional structure as hard template via nanocasting strategy. Each piece nanomesh single crystal, its c axis always perpendicular plane. highly...
Abstract A three‐component domino approach for the synthesis of chroman‐spiroquinazolin(thi)ones is described. It involves a condensation 2‐aminoacetophenones and iso(thio)cyanates followed by hetero‐Diels‐Alder annulation with 2‐hydroxybenzyl alcohol derivatives. The reaction exhibits broad substrate scope under metal‐free catalytic condition. magnified image
