Fe3O4@SiO2-(Imine-Thiazole)-Cu(OAc)2 nanocomposite catalyzed one-pot three-component synthesis of 2-Substituted benzothiazoles using S8 as sulfur source
Cu (OAc)2 was immobilized on the surface of magnetic nanoparticles modified by Imine-Thiazole acting as a ligand. This immobilization is done to fabricate a new and green magnetically recoverable copper catalyst [Fe3O4@SiO2-(Imine-Thiazole)-Cu (OAc)2]. Techniques such as ICP-OES, TEM, FT-IR, EDX, SEM, TGA, VSM, and XRD were used to characterize the structure of Fe3O4@SiO2-(Imine-Thiazole)-Cu (OAc)2 nanocomposite. To Synthesize 2-substituted benzothiazoles, the nanocomposite of Fe3O4@SiO2-(Imine-Thiazole)-Cu (OAc)2 was used as a catalyst via a one-pot three-component reaction of 2-iodoanilines, benzyl chlorides and S8. Recycling experiments revealed that a simple magnetic separation could be used to recover the copper nanocatalyst, and this nanocatalyst can be recycled eight times without any deterioration in catalytic activity.
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.
