| Abstract | ||
| A series of substituted chalcones (1-6) were synthesized and used to prepare some new five membered heterocyclic compounds (pyrazolines) (7-12) by their condensation with phenylhydrazine, and six membered heterocyclic compounds (pyrimidinones) (13-18) by their condensation with urea. All reactions were carried out under phase transfer catalysis (PTC) technique, employing tributylbenzylammonium bromide (TBBAB) as a catalyst in 50% aqueous sodium hydroxide in benzene (liquid-liquid system) .The structures of products were identified by physical and spectroscopic methods. | ||
