The application of magnetic nano particles in the field of catalysis has become a useful area of research.1 Functionalized magnetic nanoparticles (MNPs) have been employed in organic synthesis, showing excellent catalytic activities in oxidation,2 hydrogenation,3 C–C coupling,4 dihydroxylation of olefins,5 and amination6 reactions. Currently, much attention is focused on the synthesis of magnetic core-shell structures by coating a silica shell around them
