Abstract

In the last few decades in chemical science have seen efforts being made to make the process of chemical synthesis greener. The green chemistry principles demand a catalytic system that not only transforms the reacting species into profitable chemicals, pharmaceuticals, fuels, etc. at an accelerated rate but also tends to reduce the generation of waste, increase atom economy having a facile separation procedure. Nanocatalysis provides one of the paths to ensure the amplified efficacy of the catalytic process by acting as a bridge between the Homogeneous and Heterogeneous catalysts. The issue of the cumbersome separation process of isolating the nanocatalyst from the reaction medium is resolved by using magnetically separable nanoparticles-based catalysts. This review discusses the significance of magnetic nanocatalysis and its utilization in various prominent chemical transformations in organic syntheses such as hydrogenation reactions, oxidation reactions, carbon-carbon coupling reactions, click reactions, synthesis involving organocatalysis, and other miscellaneous reactions.

摘要

在过去的几十年里，化学科学界正在努力使化学合成过程更加环保。绿色化学原理需要一种催化系统，它不仅可以将反应物种以加速的速度转化为有利可图的化学品、药物、燃料等，而且还倾向于减少废物的产生，提高原子经济性，并具有简单的分离程序。纳米催化作为均相和多相催化剂之间的桥梁，提供了确保催化过程放大功效的途径之一。通过使用基于磁性可分离的纳米颗粒催化剂，解决了从反应介质中分离纳米催化剂的繁琐分离过程的问题。
