Abstract
4-Nitrochalcone was prepared through the aldol condensation of benzaldehyde with 4-nitroacetophenone using iodine as catalyst.The effects of the molar ratio of benzaldehyde to 4-nitroacetophenone,the amount of catalyst,reaction time and different solvents on the yield were discussed.The results showed that when the molar ratio of 4-nitroacetophenone(10 mmol)to benzaldehyde(12 mmol) was 1∶1.2,the amount of catalyst was 6 mmol and the reaction time was 3.0 h in ethanol under reflux,the yield of 4-nitrochalcone reached 75.51%.The product obtained with high purity.
