Abstract
|
The synthesis of a copper(I)-complexed magnetic nanoparticle catalyst is described. The catalyst was characterized using Fourier transform infrared spectroscopy (FT–IR), energy-dispersive X-ray spectroscopy (XPS), atomic absrobtion spectroscopy (AA), thermogravimetric analysis (TGA), vibrating sample magnetometery (VSM), X-ray photoelectron spectroscopy (XPS), scanning electron miscroscopy (SEM) and transmission electron microscopy (TEM). The catalyst coupled thioamides and diazocarbonyl compounds to produce diverse enaminones. The catalyst reduced the reaction times and temperature and provided enaminones in high yields and selectivity. Moreover, the catalyst can be separated by a magnet and recycled.
