Abstract

P. A. Mehta and H.B. Naik

Some chalcones (1) on condensation with hydrazine hydrate in ethanol gave 1-H-3-(4'-chloro- phen-1'- YL)-5-aryl-2-pyrazolines (2) which were converted to acetyl (3); benzoyl (4) sulphonamide (5); and nitroso (6) derivatives. These varied products have been characterised by spectral studies end screened for anti-bacterial activity.
