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.
1,3-二芳基-1H-苯并[f]苯并吡喃和1,3-二芳基-1H-苯并[f]苯并吡喃-2-基)(苯基)甲酮是通过萘酚、芳香醛和苯乙酮或1,3-二苯基丙烷-1,3-二酮与双(亚氨基)吡啶铁基催化剂4-硝基-2,6-二乙酰基吡啶双(2,4,6-三甲基苯胺)FeCl2的一锅三组分反应合成的。这种新颖、高效、快速的方法在无溶剂条件下进行超声波照射。
