Abstract Pd supported on 3,4-diaminobenzoic acid functionalized Fe3O4 magnetic nanoparticles as an organic-inorganic hybrid heterogeneous catalyst was fabricated and characterized by FT-IR, XRD, SEM, TEM, TGA, VSM, EDX, and ICP-AES techniques. The catalytic activity of the magnetic catalyst was probed through a Strecker-type reaction for one-pot synthesis of 2-methoxy-2-phenylacetonitrile derivatives
摘要 制备了负载在 3,4-二氨基苯甲酸功能化 Fe 3 O 4磁性纳米粒子上的 Pd 作为有机-无机杂化多相催化剂,并通过 FT-IR、XRD、SEM、TEM、TGA、VSM、EDX 和 ICP-AES 技术对其进行了表征. 磁性催化剂的催化活性通过 Strecker 型反应在环境和无溶剂条件下一锅合成 2-甲氧基-2-苯基乙腈衍生物进行了探测。该协议的优点是程序简单、产量高、反应时间短和环境友好的方法。催化剂很容易使用外部磁铁分离,并可重复使用,而不会显着降低其催化效率。
