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

Magnetic 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 as PowerPoint slide
