1-Acetyl-5-(4-nitrophenyl)-3-(2-thienyl)-2-pyrazoline was synthesized by the Claisen-Schmidt condensation of
3-(4-nitrophenyl)-1-(2-thienyl)-2-propene-1-one in presence of hydrazine hydrate in acetic acid and its copper complex have
been synthesized and characterized on the basis of elemental analysis, magnetic susceptibility, molar conductance, molecular
weight determination and spectral data like 1
H NMR, IR. These compounds were also screened for their antibacterial activity
against Gram positive and Gram Negative bacteria.
