Chemoselective iodination of alcohols with CeCl3·7H 2O/NaI over SiO2 under microwave irradiation

Abstract

A simple and effective procedure for conversion of primary, secondary, allylic and benzylic alcohols into the corresponding iodides is described using CeCl3·7H2O/NaI over SiO2 under microwave irradiation. Benzylic alcohols are selectively converted in the presence of saturated alcohols into their corresponding benzylic iodides under these conditions.
