Hypervalent Iodine Mediated <i>para</i>-Selective Fluorination of Anilides

A metal-free method for the direct regioselective fluorination of anilides has been developed. In the presence of bis­(<i>tert</i>-butylcarbonyloxy)­iodobenzene (PhI­(OPiv)<sub>2</sub>) and hydrogen fluoride-pyridine, the <i>para</i>-fluorination products of anilides were obtained in moderate to good yields. Because of its operational safety and the use of readily available reagents, this new procedure provides facile access to a variety of <i>para</i>-fluorinated anilides.
