| Abstract: | 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 aldehydes under solvent free conditions without catalyst was achieved in good yield. Their structures were confirmed by 1H NMR, 13 C NMR and IR spectra. |
