Eight 2-benzoyl-N-arylhydrazinecarboxamides (PhCONHNHCONHAr) (Ar=2-ClC₆H₄, 3-ClC₆H₄, 4-ClC₆H₄, 3,4-Cl₂C₆H₃, 2-MeC₆H₄, 3-MeC₆H₄, 4-MeC₆H₄,2,4-Me₂C₆H₃) have been synthesized via the reaction of N-substitutedtrichloroacetamides with benzoylhydrazine mediated by NaOH and characterized byelemental analyses, ¹H NMR and IR spectra. The biological test shows thatsome compounds have displayed significant antibacterial activities against Escherichia coli, Staphylococcus aureus and Bacillus subtilis.

Key words: substituted hydrazinecarboxamide, trichloroacetamide, synthesis, characterization, antibacterial activity
