摘要

A facile synthesis of some novel 5,7-dibromotroponocpyrazole derivatives via the condensation reaction of 3-acetyl-5,7-dibromotropolone with aromatic hydrazines is described. All the synthesized compounds were obtained in good yields of 67-88 and their structures were characterized by IR, ~1H NMR, MS, and elemental analysis.
