Abstract

The aim of the present work is to prepare different substituted 2-pyrazolines and to substantiate their structure by chemical and spectral tools. The importance of these pyrazoline derivatives arises from their wide applications for different purposes. Thus, the 1, 3diaryl-2-propen-l-ones (Ia-o) were condensed with hydrazines hydrate, phenylhydrazine, and methylhydrazine to produce 1 H-3, 5diaryl-2-pyrazolines (II Ia,-ll), 1, 3, 5-triaryl-2- ...
