Abstract

Recovery and reusability of catalysts is an important aspect in modern catalysis research especially in organic synthesis. Magnetic nanoparticles (MNPs) are very attractive, especially, for biomedical applications, among which, ferrite nanoparticles (MFe₂O₄ NPs; M = Cu, Co, Ni, Zn, Mn, etc.) stand at the boundary between homogeneous and heterogeneous catalysts, in the sense that in many cases they offer advantages from both, in terms of activity, selectivity, efficiency and re-usability. Ferrite nanocatalysts can be easily separated and recovered from the reaction mixture using an external magnet. One-pot multi-component reactions are one of the ideal synthesis methods in organic synthesis, which has received much attention in recent decades. In recent times, many publications reported in the literature based on the utilization of ferrite nanoparticles (MFe₂O₄ NPs) as a catalyst for the performance of multicomponent reactions. In this review, we discussed on the catalytic activity of MFe₂O₄ NPs in the performance of multicomponent reactions.

摘要

催化剂的回收和重复使用是现代催化研究特别是有机合成的一个重要方面。磁性纳米粒子 (MNPs) 非常有吸引力，尤其是在生物医学应用方面，其中，铁氧体纳米粒子 (MFe ₂ O ₄NP；M = Cu、Co、Ni、Zn、Mn 等）处于均相和非均相催化剂之间的边界，从这个意义上说，在许多情况下，它们在活性、选择性、效率和可重复使用性方面提供了两者的优势. 使用外部磁铁可以很容易地从反应混合物中分离和回收铁氧体纳米催化剂。一锅多组分反应是有机合成中较为理想的合成方法之一，近几十年来备受关注。最近，许多出版物在文献中报道了基于铁氧体纳米粒子（MFe ₂ O ₄ NPs）作为多组分反应性能催化剂的利用。在这篇综述中，我们讨论了 MFe ₂ O ₄的催化活性 NPs 在多组分反应中的表现。
