Synthesis and characterization of 1-formyl-3-phenyl-5-aryl-2-pyrazolines Sid, Assia Lamara, Kaddour Mokhtari, Mahieddine Ziani, Nouara Mosset, Paul Chalcones Formic acid Pyrazolines Hydrazine hydrate Fluorescence spectroscopy Spectroscopy Reaction of chalcone derivatives 1-4 with hydrazine hydrate in presence of formic acid yielded 2-pyrazolines 5-8. Structures of these compounds have been elucidated by spectroscopic methods; IR, UV, 1H NMR, 13C NMR. Their purities were confirmed by elemental analyses.
