摘要:

Aldehydes, hydrazine and ethyl acetoacetate were used for the synthesis of 4,4′-arylidene-bis (3-methyl-pyrazolones) derivatives in water. In this green synthetic protocol, the solvent water itself catalyzed the reaction via hydrogen bonding, thus avoiding the use of any other catalyst to make the work up procedure easier. One-pot, environmental friendly and convenient are the highlights.
