A magnetic catalyst based on dysprosium ions immobilized on CoFe2O4 nanoparticles has been developed for selective oxidation of organic sulfides and synthesis of symmetrical disulfides. The catalyst can be easily separated using an external magnet and shows good recyclability without significant decrease in activity.
A magnetic catalyst based on immobilization of dysprosium ions on the surface of CoFe2O4 nanoparticles has been reported and used as an efficient magnetic nanocatalyst for the selective oxidation of organic sulfides and synthesis of symmetrical disulfides containing aromatic and aliphatic sulfides and thiols. The magnetic solid catalyst has been identified using TGA, FT-IR, VSM, ICP, SEM, and XRD. Moreover, the catalyst can also be separated with an external magnet and recycled several times without any remarkable decrease in its catalyst activity. (C) 2021 Elsevier B.V. All rights reserved.
