Description
Summary:A novel hybrid magnetic ionic-liquid as a heterogeneous catalyst was synthesized by hybridization of imidazolium based-ionic liquid onto the nitrogen rich magnetic nanocomposite. The resulting catalyst (n-Fe 3 O 4 @SiO 2 -TA-SO 3 H IL) has two advantages besides recyclability: (i) high capacity of functional-SO 3 H group with imidazolium-IL cation for promoting symmetric and asymmetric Hantzsch reaction and (ii) easy recovery. Caused by the polymeric and magnetic nature of the n-Fe 3 O 4 @SiO 2 -TA-SO 3 H IL, large quantities of acidic groups were bound to the n-Fe 3 O 4 @SiO 2 -TA surface, which reduced the catalyst mass applied to the catalytic reaction. Moreover, superior catalytic performance and outstanding recyclability of n-Fe 3 O 4 @SiO 2 -TA-SO 3 H IL in mild condition make this method a green pathway for manufacture of satisfactory chemicals.
