Facile preparation and reactivity of magnetic nanoparticle-supported hypervalent iodine reagent: A convenient recyclable reagent for oxidation

A simple three-step preparation of magnetic nanoparticle-supported (diacetoxyiodo)benzene starting from 4-iodobenzoic acid is described. The nanoparticle reagent was obtained with good loading levels and has been successfully used for efficient oxidation of a wide range of alcohols. The supported reagent demonstrated comparable activity with that of its homogeneous counterpart (diacetoxyiodo)benzene and could be simply recycled with the assistance of an external magnet.
