Efficient and reusable ionic liquid stabilized magnetic cobalt nanoparticles as catalysts for aza- and thia-Michael reactions

•Magnetic cobalt nanoparticles used to catalyze aza- and thia-Michael reactions•Reaction carried out in environmentally benign conditions at room temperature•Products isolated in high yields, in short reaction times•Catalyst efficiently recycled seven times

Graphical abstractMagnetic cobalt nanoparticles, stabilized using ionic liquid [bmim]BF4, have been used for catalyzing aza- and thia-Michael reactions under environmentally benign conditions at room temperature. The products were isolated in high yields in short reaction times, while the catalyst was efficiently recycled multiple times using a magnetic field.Figure optionsDownload full-size imageDownload as PowerPoint slide
