Abstract:

The 5-alkylthio and 5-arylthiotetrazoles were efficiently synthesized from thiocyanates using Fe3O4 nanoparticles as a magnetically recoverable and reusable catalyst. The main advantages allocated to this method are elimination of hydrazoic acid as a dangerous and harmful reagent, high yields and ease of product isolation. The catalyst can be simply recovered by an external magnet and reused with no significant loss in its reactivity.

Keywords: Fe3O4 Nanoparticles, thiocyanate, sodium azide, thiotetrazole, heterogeneous catalyst.
