Magnetic Nanoparticles (CoFe2O4)‐Supported Phosphomolybdate as an Efficient, Green, Recyclable Catalyst for Synthesis of β‐Hydroxy Hydroperoxides

Magnetic nanoparticles (CoFe2O4)‐supported phosphomolybdate ([CoFe2O4@SiO2‐PrNH2‐PMo]) was readily prepared and identified as an efficient catalyst for ring‐opening of various epoxides with ethereal hydrogen peroxide (H2O2). The reaction proceeded under mild conditions to give β‐hydroxy hydroperoxides (HHPs) in high yields at room temperature, and the catalyst could be magnetically separated and recycled. magnified image
