Heterocycles. 3. Synthesis and Spectral Data of Some 2-Pyrazolines

The reaction of 1,3-diaryl-2-propen-1-ones (Ia-o) with hydrazine and methyl- and phenylhydrazine produced different substituted 2-pyrazolines (III).The structures of these products were evident from their chemical and spectroscopic analysis.
