range of 2,4,6-triaryl 1,3,5-triazine and 2-arylbenzothiazole derivatives were successfully synthesized with high to excellent yields. Compared to previously reported methods, this method has advantages such as synthesis of 2,4,6-triaryl 1,3,5-triazine and 2-arylbenzothiazole products with high to excellent yields, performance of reactions in ChCl/urea as green solvent, simple separation of the Fe3
2,4,6-三芳基1,3,5-三嗪和2-芳基苯并噻唑衍生物具有很高的生物活性潜力,存在于许多天然和医药产品中。由于这些原因,2,4,6-三芳基1,3,5-三嗪和2-芳基苯并噻唑衍生物的合成引起了合成化学家的极大兴趣。在该合成方法中,我们发现在ChCl/尿素中以KOAc为溶剂,使用Fe 3 O 4 @DH/Ph-ImH-Phen-CuCl 2纳米复合材料是一种环保且高效的催化系统,用于合成三嗪和2-芳基苯并噻唑衍生物。在此催化体系下,成功合成了多种2,4,6-三芳基1,3,5-三嗪和2-芳基苯并噻唑衍生物,且收率极高。与之前报道的方法相比,该方法具有合成2,4,6-三芳基1,3,5-三嗪和2-芳基苯并噻唑产品的优点,收率高至优异,在ChCl/尿素作为绿色溶剂中反应性能良好,仅用外部磁铁即可简单分离 Fe 3 O 4 @DH/Ph-ImH-Phen-CuCl 2纳米催化剂,Fe 3 O 4 @DH/Ph-ImH-Phen-CuCl
