An efficient procedure for rapidly synthesizing the 1,3,5-triarylpentane-1,5-diones compounds using aromatic aldehydes and aromatic ketones as starting materials by tandem aldol reactions/Michael additions under NaOH/Al2O3 and the solvent-free conditions has been described. All compounds were characterized by IR, 1H NMR and elemental analysis. Additionally, the crystal structure of 3-(2’,4’-dichlorophenyl)-1,5-diphenylpentane-1,5-dione was obtained and determined by X-ray single-crystal diffraction. The protocol offers several advantages such as a simple, eco-friendly procedure and mild reaction conditions.
