摘要：

CuO and Cu2O nanoparticles were prepared by a green method at room temperature and then employed for the synthesis of montmorillonite-K10/iron oxide/cupric oxide (MMT-K10/Fe3O4/CuO) and montmorillonite-K10/iron oxide/cuprous oxide (MMT-K10/Fe3O4/Cu2O) nanocatalysts. The properties of these nanocatalysts were explored using Fourier transformed infrared spectroscopy (FT-IR), X-ray powder diffraction (XRD), field emission scanning electron microscopy (FE-SEM), energy-dispersive X-ray spectroscopy (EDS), vibrating-sample magnetometer (VSM), and inductively coupled plasma (ICP). The catalytic activity of these heterogeneous nanocatalysts was investigated in the A(3)-coupling reaction for the synthesis of propargylamines. The results revealed that the highest efficiency was related to MMT-K10/Fe3O4/CuO nanocatalyst at 80 & DEG;C in toluene solvent. Moreover, the separation and recovery of the nanocatalysts were straightforward, efficient, and cost-effective.[GRAPIHCS]
