Fluorine containing 1,3-diarylchalchones on condensation with pentafluorophenylhydrazine in absolute ethanol, afforded the corresponding 1,3,5-triarylpyrazoles and with hydroxyl amine hydrochloride in pyridine yielded 3,5-diarylisoxazoles.Fluorinated chalchones were synthesised by condensation of the appropriate acetophenones and aromatic aldehydes in aqueous ethanolic sodium hydroxide solution.All the compounds were characterised by their analytical and ir, 1H nmr, 19F nmr and mass spectral data.Mass fragmentation patterns of these compounds have also been discussed.
