Abstract

New 3-aryl-5-styryl-2-pyrazolines have been synthesized by the reaction of (E,E)-cinnamylideneacetophenones with hydrazines. These 2-pyrazolines have also been converted into the corresponding pyrazoles by oxidation with chloranil. Structures of all new compounds have been elucidated by elemental analysis, mass spectrometry, ir and nmr spectroscopic measurements.
