Abstract

In this work, an oxovanadium(IV) complex supported on the surface of modified Fe3O4 with a silica shell has been synthesized. The obtained nanostructures were characterized using FT-IR, XRD, SEM, EDX, VSM, TGA and ICP-AES analyses. The synthesized magnetic nanocatalyst has been applied as an efficient catalyst for the synthesis of 2-amino-4H-benzo[h]chromenes via three-component one-pot reaction and also selective oxidation of sulfides to sulfoxides under solvent-free conditions. The synthesized nanocatalyst could be easily separated from the reaction mixture using an external magnet and reused several consecutive runs for both reactions without noticeable reducing in its catalytic activity.
