Chlorosubstituted heterocycles containing five members nitrogen ring have a very broad spectrum of antifungal, antibacterial and growth promoting hormonal activities. We therefore, synthesized some new chlorosubstituted 4-aroyl pyrazolines (2a-d) by the interactions of chlorosubstituted 3-aroyl flavones and 3- Aroyl Chromones with phenyl hydrazine hydrochloride an dioxane containing few drops of piperidine. The newly synthesized chlorosubstituted 4-aroyl pyrazolines were evaluated for their antimicrobial activity against E. coli, S. aureus, P. aeruginosa, P. vulgaris by disc diffusion method. The results obtained were very encouraging.
