Nano-magnetic-iron Oxides@choline Acetate as a Heterogeneous Catalyst for the Synthesis of 1,2,3-Triazoles

Nano-magnetic-iron Oxides@choline Acetate as a Heterogeneous Catalyst for the Synthesis of 1,2,3-Triazoles

In this research, four cholines supported on core–shell iron oxides, Fe 2 O 3 @MgO@Ch.OAc (choline acetate), Fe 2 O 3 @MgO@Ch.OH (choline hydroxide), Fe 3 O 4 @Ch.OAc, Fe 3 O 4 @Ch.OH, were synthesized. The synthesized catalysts were tested in 1,2,3-triazoles synthesis by the reaction of nitromethan...

Zusammenfassung:In this research, four cholines supported on core–shell iron oxides, Fe 2 O 3 @MgO@Ch.OAc (choline acetate), Fe 2 O 3 @MgO@Ch.OH (choline hydroxide), Fe 3 O 4 @Ch.OAc, Fe 3 O 4 @Ch.OH, were synthesized. The synthesized catalysts were tested in 1,2,3-triazoles synthesis by the reaction of nitromethane, aldehyde, and benzyl azide in EtOH as a green solvent. Among four synthesized heterogeneous catalysts, the Fe 2 O 3 @MgO@ch.OAc showed superior catalytic activity for the reaction and afforded the desired triazoles in good isolated yields under mild reaction conditions.
