Article Abstract
In this study, BiCl-promoted and KSO-mediated synthesis of diverse bis-sulfonyl 2,6-diarypyridines was developed one-pot stepwise (2C + 2C + 1C + 1N) annulation of two molecules of β-ketosulfone and ,-dimethylacetamide (DMAC). In the entire process, DMAC acts as the synthon of one carbon and one nitrogen in the construction of the pyridine skeleton cascade formation of single (C-C/C-N) and double (CC/CN) bonds under refluxing DMAC conditions.

In this study, a one-pot hydrothermal synthesis method was used to synthesize a novel gold-yttrium trimesic acid metal-organic framework (Au-Y-TMA MOF), demonstrating significant improvements over conventional single-metal MOFs, that is, yttrium trimesic acid (Y-TMA), in both supercapacitor applications and electrochemical antibiotic detection. The X-ray diffraction patterns of Au-Y-TMA confirmed the presence and impact of Au in the Y-TMA matrix, while field emission scanning electron microscopy (FE-SEM) images revealed a heterogeneous combination of gold nanoparticles (AuNPs) and Y-TMA, suggesting a nonuniform distribution and possible interaction. The developed half-cell supercapacitor exhibited a remarkable capacitance value of 1836 F/g at a current density of 5 A/g by galvanostatic charging-discharging (GCD) measurement.

A one-pot strategy was developed for the synthesis of α-substituted 2-benzofuranmethamines from salicylaldehydes, phenylacetylenes, and cyclic secondary amines using CuFeO as a bifunctional catalyst. The reaction proceeds at 80 °C in 1,4-dioxane using CsCO as a base, enabling sequential A-coupling, 5--dig cyclization, and 1,3-allylic rearrangement in a single operation. Unlike previous methods, this protocol employs non-precious metal catalysts and mild reagents, operates under moderate conditions, and provides direct access to α-substituted 2-benzofuranmethamines in good yields (80-96%) with broad substrate compatibility.

Strangles, a highly contagious disease caused by subspecies (), significantly impacts horse populations worldwide, with Iceland as the only exception. This disease poses serious threats to equine health and results in considerable economic losses. Consequently, the accurate, sensitive, and rapid detection of from clinical samples is essential for early warning and effective disease management.

The low-carbon strategy mandates the sustainable remediation of hexavalent chromium (Cr(VI)) contamination, driving the demand for efficient eco-adsorbents. However, current research prioritizes adsorption performance, neglecting environmental trade-offs and quantum chemical mechanisms of Cr(VI) adsorption. Here, we pioneered the first density functional theory (DFT) exploration of Cr(VI) adsorption mechanisms across chitosan (CS), polydopamine (PDA), UiO-66-NH, and polyethylenimine.

A polydopamine-glued g-CN/CoFeWO membrane, prepared one-pot synthesis, achieves complete sulfamethoxazole degradation through synergistic photocatalysis and PMS activation. It exhibits robust stability over 10 hours of continuous operation, maintaining high efficiency (97%) even in real municipal wastewater effluent, offering a novel and promising water purification strategy.
