A new hybrid catalyst has been developed by immobilizing copper acetate onto surface of cobalt ferrite magnetic nanoparticles bearing NO chelating ligand. The magnetic core of the catalyst was synthesized via ultrasound assisted co-precipitation method and characterized by FT-IR, XRD, EDX, SEM, TEM, TGA and VSM analysis. The catalyst was found to be very active for CN bond forming reaction. Coupling of amines and aryl boronic acid could be achieved in high yield in methanol in presence of triethylamine at room temperature. After completion of the reaction the catalyst could be recovered using an external magnet and reused for consecutive catalytic cycles without significant decrease in the catalytic activity.

通过将乙酸铜固定在带有N O螯合配体的钴铁氧体磁性纳米颗粒表面上，已经开发了一种新的杂化催化剂。通过超声辅助共沉淀法合成了催化剂的磁芯，并通过FT-IR，XRD，EDX，SEM，TEM，TGA和VSM分析对其进行了表征。发现该催化剂对于C N键形成反应非常活泼。在室温下，在三乙胺存在下，在甲醇中以高收率实现胺和芳基硼酸的偶联。反应完成后，可以使用外部磁体回收催化剂，并将其重新用于连续的催化循环，而不会明显降低催化活性。
