(ICP) spectroscopy. This efficient and cost effective catalyst was applied in the N-arylation reaction and the products were obtained in good to excellent yields in short reaction times. The cost-effective catalyst demonstrated high stability, which could be facilely separated from the reaction mixture by applying an external magnet and recycled at least four times with only a slight decrease in its

铜配合物。通过傅里叶变换红外光谱 (FT-IR)、X 射线衍射 (XRD)、透射电子显微 (
TEM)、扫描电子显微镜 (
SEM)、能量色散 X射线光谱 (EDS)、振动样品磁强计 (VSM) 和电感耦合等离子体 (ICP) 光谱。这种高效且具有成本效益的催化剂用于 N-芳基化反应,并在较短的反应时间内以良好至极好的收率获得了产物。具有成本效益的催化剂表现出高稳定性,通过施加外部磁体可以轻松地将其从反应混合物中分离出来,并且至少循环四次,其活性仅略有下降。图形摘要
