Abstract

This research report the development of an eco-friendly, magnetic nanocatalyst, Fe₃O₄@SiO₂-ABHA-CuCl, for the efficient synthesis of diaryl sulfides incorporating imidazo[1,2-a]pyridine scaffolds. The catalyst was successfully prepared by immobilizing CuCl on magnetic Fe₃O₄ nanoparticles modified with 4-amino-3-hydroxybenzoic acid. Characterization revealed spherical nanoparticles with a size range of 15-30 nm. The catalyst exhibited excellent catalytic activity in promoting C–H bond sulfenylation of imidazopyridines using the green solvent PEG-400. Remarkably, the catalyst demonstrated exceptional recyclability over eight consecutive cycles without significant loss of activity. Comprehensive analysis confirmed the preservation of the catalyst's magnetic properties and structural integrity after repeated use.

咪唑吡啶-硫化物-芳基衍生物的合成研究：纳米Fe3O4固载铜配合物催化咪唑吡啶的一锅C-H键磺化反应

本研究报告了一种环保的磁性纳米催化剂Fe3O4@SiO2-ABHA-CuCl的开发，用于有效合成含有咪唑[1,2-a]吡啶支架的二芳基硫化物。将CuCl固定在4-氨基-3-羟基苯甲酸修饰的磁性Fe3O4纳米颗粒上，成功制备了催化剂。表征显示球形纳米颗粒，尺寸范围为15-30 nm。该催化剂在绿色溶剂PEG-400催化咪唑吡啶的C-H键磺化反应中表现出优异的催化活性。值得注意的是，该催化剂在连续8次循环中表现出卓越的可回收性，而没有明显的活性损失。综合分析证实，经反复使用后，催化剂的磁性能和结构完整性得以保存。

期刊介绍： The Journal of Sulfur Chemistry is an international journal for the dissemination of scientific results in the rapidly expanding realm of sulfur chemistry. The journal publishes high quality reviews, full papers and communications in the following areas: organic and inorganic chemistry, industrial chemistry, materials and polymer chemistry, biological chemistry and interdisciplinary studies directly related to sulfur science. Papers outlining theoretical, physical, mechanistic or synthetic studies pertaining to sulfur chemistry are welcome. Hence the target audience is made up of academic and industrial chemists with peripheral or focused interests in sulfur chemistry. Manuscripts that truly define the aims of the journal include, but are not limited to, those that offer: a) innovative use of sulfur reagents; b) new synthetic approaches to sulfur-containing biomolecules, materials or organic and organometallic compounds; c) theoretical and physical studies that facilitate the understanding of sulfur structure, bonding or reactivity; d) catalytic, selective, synthetically useful or noteworthy transformations of sulfur containing molecules; e) industrial applications of sulfur chemistry; f) unique sulfur atom or molecule involvement in interfacial phenomena; g) descriptions of solid phase or combinatorial methods involving sulfur containing substrates. Submissions pertaining to related atoms such as selenium and tellurium are also welcome. Articles offering routine heterocycle formation through established reactions of sulfur containing substrates are outside the scope of the journal.
