Polyphosphoric acid functionalized silica-coated magnetic nanoparticles with core-shell structure (NiFe2O4@SiO2-PPA) has been used as a magnetically recyclable green catalyst for the one-pot three-component synthesis of 2-thioxoquinazolinones by the reaction of isatoic anhydride, primary amines and thiourea under neat conditions. The catalyst is readily recovered by simple magnetic decantation and can be recycled five times with no significant loss of catalytic activity.

An efficient protocol for the one-pot reaction of isatoic anhydride (=1,2-dihydro-4H-3,1-benzoxazine-2,4-dione), primary alkylamines, and heterocumulenes (isothiocyanates and isocyanates) in H2O catalyzed by magnetically recoverable Fe3O4 nanoparticles is described. Copyright
