Main Article Content
Abstract
The research included the preparation of new pyrazole derivatives from the condensation of the benzoyl acetone with carboxylic acid hydrazide in ethanal as a solvent. This reaction included two steps from the tetra surfaces nucleophilic addition and cyclisation process in second step. The pyrazole derivatives products were reacted with different aldehydes or ketones to give heterocyclic bicyclic compounds.
The prepared compounds were characterized by infrared, and Nuclear Magnatic resonance spectroscopy and the completing of the reaction was characterized by thein.
