  In this research, superparamagnetic manganese ferrite nanoparticles were synthesized following a co-precipitation method, and subsequently coated with 3-aminopropyltriethoxysilane (APTES) through a silanization reaction. Manganese ferrite nanoparticles afforded bidentate ligands as a result of the reaction between isatoic anhydride and amino-functionalized MnFe2O4. The amino-functionalized nanoparticles were treated with nickel acetate, giving the immobilized nickel complex. Finally, catalytic properties of the prepared nanoparticles were examined by a green synthesis of spirooxindoles in water and they showed excellent catalytic activity. Recovery of the catalyst was simply achieved by applying an external permanent magnet. The isolated catalyst was reused for new reaction runs without significant loss of catalytic activity.

  在这项研究中，采用共沉淀法合成了超顺磁性锰铁氧体纳米颗粒，并通过硅烷化反应用3-氨丙基三乙氧基硅烷（APTES）进行了包覆。锰铁氧体纳米颗粒由于异苯酸酐与氨基功能化MnFe2O4之间的反应而赋予了双齿配体。氨基功能化的纳米颗粒与醋酸镍反应，形成了固定化的镍复合物。最后，通过在水中绿色合成脊环氧喹啉，考察了所制备纳米颗粒的催化性质，结果表明它们具有优异的催化活性。催化剂的回收只需应用外部永久磁铁即可轻松实现。分离的催化剂在新的反应中重复使用，没有显著降低催化活性。
