SYNTHESIS AND CHARACTERIZATION OF SOME NEW SERIES OF PYRAZOLINE DERIVATIVES

Abstract: Pyrazolines are well known and important nitrogen containing five membered heterocyclic compounds. Pyrazoline derivatives have been extensively studied because of their ready accessibility through synthesis, diverse chemical reactivity, various biological activities and variety of industrial applications. In the present study, Novel pyrazoline derivatives were carried out by cyclization of acrylamide derivatives with hydrazine hydrate in the presence of benzoic acid. Structures of the newly synthesized compounds were assigned on the basis of elemental analysis, IR, 1H NMR, and 13C NMR.

Keywords: Pyrazoline derivatives, spectral analysis, Substituted pyrazoline, Synthesis.
