Abstract: Thirty new pyrazole acylhydrazine derivatives containing carboxylate,sulfonylate, hydrazone and dipyrazole ketone were synthesized from the intermediate 1, 3,4-substituted-5-pyrazole carboxylic hydrazide(7,8).Their structures were confirmed by 1H NMRand elemental analysis.The preliminary biological tests showed that several compounds havesome fungicidal and herbicidal activity.
