A Recyclable Ferrite–Co Magnetic Nanocatalyst for the Oxidation of Alcohols to Carbonyl Compounds

Magnetic cleansing: A magnetic Fe3O4–Co catalyst was prepared using inexpensive precursors and its catalytic activity was tested for the oxidation of alcohols using tert-butyl hydroperoxide (TBHP) as the oxidant. The corresponding carbonyl compounds were obtained in good to excellent yields (see scheme); furthermore, this magnetic catalyst could be separated by magnetic decantation without significant loss in activity.
