Abstract

Sulfonic acid-supported vanillin/bis indolylmethane-functionalized Fe₃O₄@SiO₂-Propyl NPs were prepared and characterized by FT-IR, XRD, FE-SEM, TEM, VSM, EDX, DLS, and TGA-DTG. The catalytic efficiency of the prepared nanoparticles was subsequently investigated for the effective synthesis of imidazoquinazolines via the one-pot condensation of 2-aminobenzimidazole, aryl aldehydes, and cyclohexanone or dimedone under solvent-free condition. Some thiazoquinazolines also were prepared via the multicomponent reaction of aldehydes, dimedone, and 2-aminobenzothiazol under solvent-free condition,. This avenue is really suitable because it makes a high yield of product, doesn’t take too long, doesn’t need harmful materials and solvents, its work-up is easy and the catalyst is reusable.

磺酸负载香兰素/双吲哚甲烷功能化Fe3O4@SiO2-propyl NPs作为合成咪唑喹唑啉类、咪唑喹唑啉类和噻唑喹唑啉类绿色、高效、磁可回收催化剂

制备了磺酸支持的香兰素/双吲哚甲烷功能化 Fe3O4@SiO2-Propyl NPs，并通过 FT-IR、XRD、FE-SEM、TEM、VSM、EDX、DLS 和 TGA-DTG 对其进行了表征。随后，在无溶剂条件下，研究了所制备纳米粒子在通过 2-氨基苯并咪唑、芳基醛、环己酮或二甲基酮的一锅缩合反应有效合成咪唑喹唑啉类化合物中的催化效率。一些噻唑喹啉类化合物也是在无溶剂条件下通过醛、二咪酮和 2-氨基苯并噻唑的多组分反应制备的。这种方法非常适合，因为它产率高，耗时短，不需要有害材料和溶剂，操作简单，催化剂可重复使用。

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.
