β-Cyclodextrin coated Fe3O4 nanoparticles: a simple preparation and application for selective oxidation of alcohols in water

a magnetically separable catalyst was synthesized via a carbodiimide activation process with β-cyclodextrin functionalized by core-shell nanoparticles (fe3o4/sio2/cm-β-cd). the catalyst presented high activity for selective oxidation of various alcohols with naocl as oxidant and water only as the solvent. a substrate-selective and transition metal-free process was achieved with easy separation of the catalyst.
