The microwave-enhanced synthesis of 1-phenyl-3-methyl-4-arylmethylenepyrazol-5-ones and aryl-bis(1-phenyl-3-methyl-5-pyrazolon-4-yl)methane from 1-phenyl-3-methylpyrazol-5-one with aromatic aldehydesunder solvent-free conditions without catalyst was achieved in good yield. Their structures were confirmed by 1H NMR, 13C NMR and IR spectra.

Key words: microwave irradiation, solvent-free, uncatalyzed, 1-phenyl-3-methylpyrazol-5-one, aromatic aldehyde
