چکیده

The current work describes the successful synthesis of a magnetic CoFe 2 O 4 centered asparagine functionalized noble metal (M = Cu, Ni) anchored nanocomposite. The novel materials, synthesized by post-functionalization approach, have been characterized by XRD, SEM, EDX, X-ray elemental mapping, FT-IR and VSM studies. The materials are proved to be efficient heterogeneous catalyst in the synthesis of diarylthioethers by C-S cross coupling reaction and 5-substituted 1H-tetrazoles by azide-alkyne cycloaddition reaction under green conditions. The current methodology is advantageous in terms of simplicity of procedure, facile synthesis, high yield in short reaction time, easy magnetic isolation and reusability of catalysts in consecutive runs with insignificant change in catalytic activity.
