چکیده
|
An efficient and eco-friendly method is introduced for the synthesis of 4,4'-(arylmethylene)-bis-(1h-pyrazol-5-ols) by the condensation reaction of two equivalents of 5-methyl-2-phenyl-2,4-dihydro-3h-pyrazol-3-one with various aromatic aldehydes, catalyzed by the boehmite nanoparticles (bnps). this heterogeneous catalyst was recycled and used in four runs for the reaction between benzaldehyde and 3-methyl-l-phenyl-5-pyrazolone without any loss of its catalytic activity.
