Abstract Synthesis of 1,6-diamino-4-phenyl-3,5-dicyano-2-pyridone derivatives via a one-pot, three-component reaction of aryl aldehydes, malononitrile, and cyanoacetic hydrazide at room temperature using KF-Al2O3 as a recyclable catalyst have been developed. The reaction proceeds through the initial Knoevenagel condensation between aldehyde and malononitrile in the presence of KF-Al2O3 to form the
