Magnetically recoverable Fe₃O₄@SiO₂@SBA-3@2-ATP-Cu: an improved catalyst for the synthesis of 5-substituted 1H-tetrazoles.

ABSTRACT: Functionalization of Fe₃O₄@SiO₂@SBA-3 with double-charged 3-chloropropyltrimethoxysilane (CPTMS) and 2-aminophenol, followed by mechanical mixing of the solid product with copper(i) chloride produces a new, greener and efficient Fe₃O₄@SiO₂@SBA-3@2-ATP-Cu catalyst for the synthesis of 5-substituted 1H-tetrazoles. XRD, SEM, atomic absorption, TGA, N₂ adsorption-desorption, and VSM analyses were performed for the characterization of the Fe₃O₄@SiO₂@SBA-3@2-ATP-Cu structure. Nitrogen adsorption-desorption analysis revealed that Fe₃O₄@SiO₂@SBA-3@2-ATP-Cu has a surface area of 242 m² g^-1 and a total pore volume of 55.72 cm
