Catalysis is one of the hottest research topics in chemistry. In recent years, metal complexes attracted great interest as catalysts towards various types of organic reactions. However, these catalysts, in most cases, suffer from the deficits during their recovery, recycling and the difficulty in separation of catalysts from the products. Therefore, the design and synthesis of recoverable and recyclable catalyst is very important aspect in catalysis. The aim of this review article is to highlight the speedy growth in the synthesis and catalytic applications of magnetic nanoparticles (Fe3O4, MNPs) supported N-heterocyclic carbene (NHC) and amine based metal complexes in various organic reactions. Furthermore, these catalysts can be easily separated from the reaction media with the external magnet and reused various times without a substantial loss of catalytic activity.

AbstractThe sulfoxidation of sulfides have received special attention in organic synthesis especially in medical chemistry because compounds containing S=O bonds (sulfoxides) are privileged structural scaffolds for building pharmacologically and biologically active molecules. Magnetic separation is an efficient strategy for the rapid separation of catalysts from reaction medium and an alternative to time-, solvent-, and energy-consuming separation techniques. In recent times, many protocols based on using magnetically recoverable nano-catalysts have been reported for the oxidation of sulfides to the sulfoxides. This review is focused on metal complexes, acid, and bromine reagents supported on magnetic nanoparticles and their applications as magnetically recoverable nano-catalysts in the sulfoxidation reactions.
