The hydrazide on treatment with acid chlorides gave diacylhydrazines, whereas with arylsulfonyl chlorides acyl(arylsulfonyl)hydrazines were obtained. The latter two types of compounds were tested for their antibacterial and antifungal activities whereas 1,3,4-oxadiazole derivatives were tested for their herbicidal activity.
Synthesis, Characterization, and Biological Activities of Some 3,5,6-Trichloropyridine Derivatives. -Oxadiazoles (III) are tested for herbicidal activity while hydrazides (V) are screened for antibacterial and antifungal activities. (III) reveal potent effects against the weeds Cynadon dactylon and Cuprus rotundus; (Vd) shows moderate activity against E. coli and S. albus. -(CHAVAN, V. P.; SONAWANE, S. A.; SHINGARE, M.
