## Dedicated to Professor Dr. Fritz Sauter on the occasion of his 75 th birthday 1-Acetyl-and 1-propionyl-2-pyrazolines 11-27 have been synthesized by the reaction of (3coumarinyl)chalcones 1-10 with hydrazine in hot acetic acid or propionic acid. While 5-aryl-3-(3coumarinyl)-1-phenyl-2-pyrazoline
The reaction of dibenzylideneacetones or E,E-cinnamylidene-acetophenones and hydrazine hydrate provided 1-propionyl derivatives of 5-aryl-3-styryl-2-pyrazolines and 3-aryl-5-styryl-2-pyrazolines. These unsaturated ketones afforded 1-(2-carboxyphenyl) or 1-(4-carboxyphenyl) 5-aryl-3-styryl-2-pyrazoli
