[PySO3H]FeCl4 as a magnetic molten salts was also investigated. Three categories of six membered O-heterocyclic compounds such as 2-amino-4H-chromene, 2-amino-4,8-dihydropyrano and 2-amino-4H-pyrans were prepared in the presence of a catalytic amount of the above said molten salts. These synthesized O-heterocyclic compounds are highly regarded due to their biological activities.
