;2006, 23(4): 447-449.
-
3,3'-Dinitrochalcone was synthesized by the Claisen-Schmidt condensation of nitrobenzaldehyde and nitroacetophenone,which was reduced to 3,3'-diaminochalcone by 85% hydrazine hydration with FeCl3·6H2O/C.The product was characterized by elemental analysis,melting point,IR,and 1H NMR measurements.The factors influencing the product yield were also discussed.Co MPared with previous methods in the literature,the present procedure has the advantages of milder conditions,lower cost,easier work-up,high product yield(78.6%) and is environmental friendly.
