Magnetic nanoparticles (MNPs) has been one of the most noteworthy catalyst support,
offering the advantages of their easy preparation and functionalization, large surface area
ratio, superficial recovery and easy separation by an external magnet, low toxicity and price
[1]. The oxidation of sulfides to sulfoxides is great importance in organic synthesis. Chiral
sulfoxide intermediates can be found in pharmaceuticals [2]. In recent years many transition
metal catalysts systems have been reported for sulfoxidation but many of these systems suffer
from one or more limitations, such ashard separation from the reaction mixtures, which lead
to lower the purity of the products, leaching of metal and expensive materials [3]. In this
light, herein we have proposed a highlyefficient method for synthesis of sulfoxides using
H2O2 as green oxidant catalyzed by Cu(II)-imine-dopamine@Fe3O4 magnetic nanoparticles.
