An environmentally benign, clean and general protocol was developed for the synthesis of aryl and heteroaryl trans-chalcones. This method involved solvent-free reaction conditions under microwave irradiation in the presence of a clay-based catalyst, and afforded the target compounds in good yields and short reaction times. Furthermore, the same conditions allowed the synthesis of symmetrical, diarylmethylene-α
为合成芳基和杂芳基反式查耳酮开发了一种环境友好、清洁和通用的协议。该方法涉及在粘土基催化剂存在下在微波辐射下的无溶剂反应条件,并以良好的收率和较短的反应时间提供目标化合物。此外,相同的条件允许从芳香醛和酮合成对称的二芳基亚甲基-α,β-不饱和酮。
