In this research, SO 3 H-functionalizedphthalimide (SFP) has been prepared through simple reaction of phthalimide with chlorosulfonic acid, and characterized using FT-IR, 1 H NMR, 13 C NMR, SEM (scanning electron microscopy), mass and TG (thermal gravimetric) spectra. Afterward, the solid acid has been utilized as an efficient, green, heterogeneous and recyclable catalyst for the solvent-free synthesis of 2-amino-4 H -chromenes by the one-pot multi-component reaction of aromatic aldehydes with malononitrile and 1-naphthol under thermal (70 °C) and microwave (540 W) conditions.
