Abstract. 2-[(2-PyridylMethyl)Amino]Acetic acid (PMAA) functionalized Fe 3 O 4 superparamagnetic nanorods e ciently catalyzed three-component reaction of malononitrile, aromatic aldehydes, and phenolic or enolic components, such as -naphthol, -naphthol, dimedone, or kojic acid, to synthesize a variety of chromene or pyran derivatives in good to high yields. PMAA functionalized Fe3O4 magnetic nanorods were prepared via simple coprecipitation in an aqueous solution of Fe 2+ and Fe 3+ ions using NH 4 OH in the presence of glycine, followed by subjecting it to 2-pyridine carbaldehyde and then, NaBH 4 -mediated reduction of in-situ generated imine. Obtained nanorods were characterized by FT-IR, XRD, TGA, SEM, EDX, TEM, BET, and VSM analysis.
