SYNTHESIS OF 5,7-DIBROMOTROPONO[c]PYRAZOLE DERIVATIVES

[摘要]：A facile synthesis of some novel 5,7-dibromotropono[c]pyrazole 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, H-1 NMR, MS, and elemental analysis.
