FT‐IR, SEM, TEM, BET, and VSM. This hybrid magnetic nanocomposite was employed as heterogeneous catalyst for α‐amino nitriles synthesis through three‐component condensation reaction of aldehydes (ketones), amines, and trimethylsilyl cyanide in EtOH, at room temperature. The recoverability and reusability was admitted for the heterogeneous magnetic catalyst; no significant reduction of catalytic activity
在
氨基修饰的Fe 3 O 4 @SiO 2纳米粒子存在下,通过溶剂热法制备了高度多孔的
金属有机骨架MIL-101(Fe),以实现Fe 3 O 4 / MIL-101( Fe)纳米复合材料,其特征在于XRD,FT-IR,
SEM,
TEM,BET和VSM。这种杂化磁性纳米复合材料在室温下通过醛(酮),胺和三甲基甲
硅烷基
氰化物在EtOH中的三组分缩合反应,被用作α-
氨基腈合成的非均相催化剂。均相磁性催化剂具有良好的可回收性和可重复使用性。即使在五个连续的反应循环后也未观察到催化活性的显着降低。
