Synthesis of some new substituted 1,3,5-triaryl pyrazolines

الملخص EN

A series of substituted chaconnes were synthesized by the Calamines-Schmidt condensation of substituted Benz aldehydes and acetophenones.

The reaction of these chaconnes with phenyl hydrazine were studied under phase transfer catalysis (PTC) conditions employing tetra butyl ammonium iodide (TBAI) as a catalyzed to synthesize 1, 3, 5-pyrazolines.

The structures of all products were elucidated by physical and spectroscopic method.
