Abstract

Postsynthetic modification of magnetic nano ferrites (Fe₃O₄) has been accomplished by anchoring glutathione and dopamine on the surface. The Cu nano particles immobilized over these surfaces were investigated for the coupling and cyclo addition reactions. The Fe₃O₄-DOPA-Cu (nano-FeDOPACu) catalyst showed activity for C-S coupling reactions whereas the Fe₃O₄-Glut-Cu (nano-FGTCu) catalyst was active for cyclo addition reactions and not vice versa.
