ABSTRACT:
Novel 1,4-disubstituted-3-nitropyrazoles having antimicrobial, parasiticidal, and herbicidal activity are prepared by a reaction sequence of which the individual steps are conventional. The new 3-nitropyrazoles are characterized by a 1-substituent and a usually carbonyl-containing 4-substituent. The novel 3(5)-nitro-4-pyrazolecarbonitrile is obtained as an intermediate in the preparation of the biologically-active compounds. Preferred compounds are 1-alkyl or -alkenyl-4-pyrazolecarboxamides are carbonitriles. The new compounds are particularly useful for the control of bacterial animal diseases.
