Synthesis of Some New Pyrazoline Derivatives and Related Compounds from Chalcones and their Antibacterial Activity

摘要

Chalcones on condensation with hydrazine hydrate in ethanol gave 2-pyrazolines which were converted to acetyl,benzoyl,p-acetailide,sulphonyl and nitroso derivatives. These products have been characterised by specral studies and screened for antibacterial activity.
