A new green catalyst: 1,3,5-triazine-functionalized bisimidazolium dichloride tethered SPION catalyzed Betti synthesis†
Abstract
A unique dicationic ionic liquid tethered to superparamagnetic iron oxide nanoparticles as a green and powerful catalyst for the efficient synthesis of Betti bases in high to excellent yields has been evaluated. Due to the high magnetization of the catalyst, it can be satisfactorily recovered by a simple external magnet. The catalyst could then be recycled and reused at least six times without any loss of activity.
