RuCl3-catalyzed oxidation of iodoarenes with peracetic acid: new facile preparation of iodylarenes.

New facile methodology for the preparation of pentavalent iodine compounds using peracetic acid as an oxidant in the presence of catalytic amounts of ruthenium trichloride is described. The new procedure allows the preparation of several previously unknown iodylarenes bearing strongly electron-withdrawing CF3 groups in the aromatic ring.
