Five chalcones were synthesized via the aldol condensation reaction of acetophenone or parasubstituted acetophenones with 1-phenyl-3-methyl-5-phenoxyl-pyrazol-4-aldehyde, which reacted with two kinds of hydrazine in glacial acetic acid under refluxing to give a series of bipyrazoline derivatives. In this synthetic course, glacial acetic acid is not only a solvent, but also a catalyzer.
