Syntheses and Characterizations of some New Pyrazolines Derived from Chalcone Compounds

Abstract

AbstractAn efficient and practical synthesis of six compounds of pyrazolinederivatives structures was achieved through cyclization of hydrazinehydrate with α,β--unsaturated ketones (chalcones) using glacial aceticacid as catalyst under thermal conditions. These compounds have beencharacterized by FT-IR, elemental analysis (C.H.N.) and 1H NMRspectroscopy
