In recent years, the new technology has been used in the synthesis of chalcone compounds, under the 343 K condition carrying on the response in the temperature. It takes benzaldehyde and acetophenone as raw material, BF4 as resolver and the hydrotalcite as the catalyst, the yield of chalcone can reach 98.5%. This method has some advantages including shorter reaction time, higher yield and simpler operation.
