Ni-S-(PROPYL)2-AMINOBENZOTHIOATE ON Fe3O4 NANOPARTICLES: EFFICIENT AND RECYCLABLE CATALYST FOR ORGANIC REACTIONS

Ni-S-(propyl)2-aminobenzothioate supported on functionalized Fe3O4 magnetic nanoparticles (Ni-SPATB/Fe3O4), has been reported for the one-pot synthesis of polyhydroquinoline derivatives and also for selective oxidation of sulfides to sulfoxides as a high reusable and efficient nanocatalyst. The prepared nanoparticles was characterized by FT-IR, VSM, TGA, SEM, XRD and ICP-OES techniques. This nanocatalyst was easily recovered using external magnet and reused for several times without significant loss of its catalytic efficiency.
