The polystyrene-supported CuI–imidazole complex catalyst was prepared and characterized by IR spectroscopy, elemental analysis, SEM/TEM and TG/DSC. The complex catalyst was globular with the size of 400–500nm and showed a good thermal stability at high temperature. The immobilized Cu metal in the complex catalyst was about 0.85 mmol/g. By using the catalyst, aza-Michael reaction of imidazoles to α, β-unsaturated compounds was ...
