Magnetically retrievable 2-(2-Pyridyl)benzimidazole-Cu(I) on SBA-15@Fe₃O₄ for sodium Azide-Induced amination of Aryl halides.

ABSTRACT: This study reports the synthesis and thorough characterization of a novel copper catalyst immobilized on magnetic mesoporous silica (Fe₃O₄@SBA-15). The catalyst preparation involved stepwise functionalization of Fe₃O₄@SBA-15 through sequential treatment with (3-aminopropyl)triethoxysilane (APTES), trichlorotriazine, and 2-(2-pyridyl)benzimidazole, resulting in Fe₃O₄@SBA-bis(PBI). Subsequent coordination with CuI in acetonitrile produced the final catalyst complex, Fe₃O₄@SBA-bis(PBI)-Cu. Extensive characterization was performed using standard spectroscopic techniques. The copper content of the catalyst was determined by atomic absorption spectroscopy to be 0.866 mmol g^-1 (5.5 wt%). Catalytic p
