SYNTHESIS OF SOME 3-AROYL-4-ARYL-2-PYRAZOLIONES

Addition of diazomethane to α,β-unsaturated ketones in the presence of base at low temperature gave 3-aroyl-4-aryl-2-pyrazolines (IIa).Benoylation, benzenesulfonylation and nitrosation of IIa yielded the corresponding 1-substituted derivatives (V, VI and VII) IR and (1)H-NMR spectral data established the stuctures of the new compounds.

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
