Abstract

The reactions of some unsaturated a,b-ketones with hydrazines and some its derivatives were investigated. unsaturated a,b-ketones reacted with hydrazine derivatives RNHNH₂ in acetic acid/sodium acetate to give 1-R-3,5-diaryl-2-pyrazolines. The reaction of unsaturated a,b-ketones with hydrazine, however, gave 1-acetyl-3,5-diaryl-2-pyrazolines. The structure of the obtained compounds were confirmed by IR, UV, NMR spectra. Photoluminescence of some compounds were also investigated.
