3,3＇-difluorochalcone was synthesized for the first time through Claisen-Schmidt condensation between 3- fluorobenzaldehyde and 3-fluoroacetophenone using sodium hydroxide solution as the catalyst. The product＇s structure was characterized by FT-IR, 1H-NMR, and UV-Vis spectrca. The result showed that this method provided high yield （92.4 % ） as well as short reaction time and easy operation.
