analysis (TGA), SEM/EDX, elemental mapping, TEM, ICP-OES, and elemental analysis (EA). This nanocatalyst was found to be highly effective for synthesis of various benzothiazole derivatives in excellent yields under solvent-free conditions. Furthermore, bis- and tris-benzothiazoles were smoothly synthesized from dinitrile and trinitrile in the presence of this catalytic system. High yields and purity
制备了固定在埃洛石纳米管 [(APTDP)(FeCl 4 ) 2 @HNT]上的氨丙基-1,3,5-三嗪-2,4-二磷鎓四氯高铁酸盐,并使用不同的技术(如 FT-IR、热重分析 (TGA))对其进行了充分表征。 )、SEM/EDX、元素图谱、TEM、ICP-OES 和元素分析 (EA)。人们发现这种纳米催化剂在无溶剂条件下非常有效地以优异的产率合成各种苯并噻唑衍生物。此外,在该催化体系的存在下,由二腈和三腈顺利合成了双苯并噻唑和三苯并噻唑。高产率和纯度、简单的后处理程序、高催化活性(高 TON 和 TOF)以及催化剂的易于回收和可重复使用性,使该方法成为目前制备这些重要杂环化合物的方法的有用且重要的补充。
