Clay Catalysis: Dry Condensation of 3-Methyl-1-phenyl-5-pyrazolone with Aldehydes under Microwave Irradiation
Villemin, Didier,Labiad, Bouchta
, p. 3213 - 3218 (2007/10/02)
3-Methyl-1-phenyl-5-pyrazolone (1) and arylcarboxyaldehydes (2) were condensated to 1-phenyl-3-methyl-4-(arylmethylene)-5-pyrazolone (3) in presence of acidic clay KSF without solvent under microwave irradiation.
