Abstract
|
An efficient and eco-friendly method is reported for the chemoselective oxidation of sulfides to sulfox-ides in good to high yields using 30% H2O2in the presence of catalytic amounts of N-Propylsulfamic acid supported onto magnetic Fe3O4nanoparticles (MNPs-PSA) under solvent-free conditions at room tem-perature. Various types of aromatic and aliphatic sulfides possessing functional groups such as alcohol, ester, and aldehyde are successfully and selectively oxidized without affecting sensitive functionalities. The magnetic nanocatalyst can be readily recovered easily by applying an external magnet device and reused for at least 10 reaction runs without considerable loss of reactivity
