在室温,超声波辅助、无溶剂条件下,Zn(OTf)2为催化剂有效地催化胺与α,β-不饱和化合物的Michael加成反应,可快速、高收率的得到相应的Michael加成产物。该方法除了具有实验简单、较好的底物适应性和选择性外,还具有反应速度快、实验后处理简便及对环境友好的优点,这些将有助于化学反应的绿色化进程。所有的Michael加成产物结构均经质谱、红外光谱和核磁共振氢谱分析进行确证。 The addition of Zn (OTf) 2 as catalyst catalyzed the Michael addition of amines to α, β-unsaturated compounds efficiently at room temperature with ultrasound-assisted and solvent-free conditions. The corresponding Michael additions were obtained in high yield . In addition to its simple and good substrate adaptability and selectivity, the method has the advantages of fast reaction speed, convenient post-experiment processing and environmental friendliness, which will contribute to the green process of chemical reaction. All Michael addition product structures were confirmed by mass spectroscopy, infrared spectroscopy and 1H nuclear magnetic resonance spectroscopy.
