1,3-Diaryl-1H-benzo[f]chromenes and 1,3-diaryl-1H-benzo[f]chromen-2-yl)(phenyl)methanones have been synthesized by one-pot three-component reaction of naphthols, aromatic aldehydes, and acetophenone or 1,3-diphenylpropane-1,3-dione, with the bis(imino)pyridine iron-based catalyst 4-nitro-2,6-diacetylpyridinebis(2,4,6-trimethylaniline)FeCl2. This novel, efficient, and rapid method is performed under solvent-free conditions with ultrasonic irradiation.
