<正>Methods for the formation of C-S bonds are important tools in synthetic chemistry,but are comparatively less well understood than C-N or C-O bond formation.¹ Nanoscale catalysts offer several advantages over traditional methodologies,including an increase in exposed active surface area for selective binding of substrates,which makes this a more effective process.²Recently,the uniformed monodisperse magnetic nano-ligand Fe₃O₄@Si（CH₂）₃NH₂（MNL B）
