Abstract

A magnetic organic-inorganic hybrid of Fe3O4@SiO2-functionalized propylpiperazine-1,4-diium tungstate (A) nanoparticles with a spherical structure was prepared and completely characterized by XRD, SEM, TGA-DTA, and FT-IR spectral techniques. The magnetic hybrid was used in the oxidation of symmetrical sulfides to symmetrical sulfoxides under ambient conditions. The excellent yields of sulfoxides, easy operation, and recovery, magnetic properties of the catalyst, and environmentally friendly system are the key advantages of this method.   Highlights

  • The excellent yields of sulfoxides
  • Easy operation and recovery
  • Magnetic properties of the catalyst
  • Environmentally friendly system
