Studies on Pyrazolines: Syntheses, Pyrolysis and Reactivity of Some 3-Aroyl-4-aryl-δ2-pyrazolines

Δ2-Pyrazolines (IIb-i)have been obtained through cycloaddition of diazomethane to chalcones (Ib-i).The structure (II) has been firmed established on the basis of PMR and (13)C NMR data.Pyrolysis and chemical reactivity of II are described.These

SYNTHESIS OF 3-BENZOYL-4-PHENYL-2-PYRAZOLINES BY THE REACTIONS OF CHALCONES WITH DIAZOMETHANE

3-Benzoyl-4-phenyl-2-pyrazolines (IIIa-k) have been synthesized by the reactions of chalcones (1a-k) with diazomethane.The structures of the compounds prepared have been elucidated by means of UV, IR, (1)H- and (13)C-NMR spectroscopic methods.The conforma
