摘要：

Under the high-speed vibration milling conditions, K2CO3 was found to be a very efficient catalyst for the solvent-free Michael reactions of 1,3-dicarbonyl compounds with chalcones and azachalcones. In most cases, conventional side reactions were avoided and thus excellent yields were achieved. The influences of other catalysts and the vibration frequency on the Michael reaction were investigated.
