英文摘要：

Chalcone and azachalcone are widely applied in the field of pharmaceutical intermediate and organic syn- thesis. Therefore, it is of great importance to develop a novel, highly efficient and environment-friendly method for the synthesis of these compounds. Through a mechanical vibration method under solid phase condition, a series of chalcones and azachaleones are synthesized from various benzaldehydes with acetophenone and 2-acetyl pyridine, in which NaOH is used as the catalyst and a vibration frequency of 30 Hz is employed during 40-80 min. All the prod- ucts are characterized by melting point, IR and HNMR analysis. The results indicate that this mechanical vibration process exhibits very high selectivity and yield. Compared with conventional reaction conditions in solution, the pre- sent method is highly efficient, green and economical.
