Magnetite nanoparticles (MNPs) have proved to be a useful support for heterogeneous catalysis. We have synthesized Fe3O4 MNPs functionalized with a copper(II) complex, and tested the resulting material as a heterogeneous nanocatalyst. The catalyst was tested for aldol condensation reactions between aliphatic/aromatic aldehydes and rhodanine or thiazolidine-2,4-dione (TZD) derivatives under reflux in
磁铁矿纳米颗粒 (MNPs) 已被证明是多相催化的有用载体。我们已经合成了用铜 (II) 络合物功能化的 Fe3O4 MNP,并测试了所得材料作为非均相纳米催化剂。对该催化剂进行了脂肪族/芳香族醛与若丹宁或噻唑烷-2,4-二酮(TZD)衍生物在乙醇中回流的羟醛缩合反应测试,得到了高产率的目标产物。环境友好的化学、反应时间短、后处理简单、产率高以及新型纳米催化剂的可重复使用性是本研究的有益特征。通过扫描电子显微镜、振动样品磁强计、热重法、X 射线衍射和能量色散 X 射线分析表征纳米催化剂。
