Polymer-Supported Hypervalent Iodine Reagent Mediated Synthesis of α-Azidoketones

The reaction of aryl ketones with sodium azide using polymer-supported bis(trifluoroacetoxyiodo)-benzene (PSBTI) in the presence of trifluoroacetic acid (TFA) to prepare α-azidoketones in one-pot conditions is reported.
