A NEW METHOD TO SYNTHESIZE 3,5-DIARYLPYRAZOL DERIVATIVES
Twelve 3, 5-diarylpyrazoles have been synthesized by microwave-assisted condensation reaction in a short and concise manner using various aromatic aldehydes and aromatic ketones as starting materials. The corresponding products were obtained in good yields (87-96%). All products were identified by M...

| Sumario: | Twelve 3, 5-diarylpyrazoles have been synthesized by microwave-assisted condensation reaction in a short and concise manner using various aromatic aldehydes and aromatic ketones as starting materials. The corresponding products were obtained in good yields (87-96%). All products were identified by MS, ¹H NMR, 13C NMR and elemental analysis. The advantages of this novel protocol include the excellent yield, operational simplicity, short time and the avoidance of the use of expensive catalysts. |
