An easy, safe, and effective method for preparing (diacetoxyiodo)arenes from iodoarenes is presented. Addition of trifluoromethanesulfonic acid (triflic acid) as a promoter causes a drastic increase in the yield of (diacetoxyiodo)arenes in the reaction of iodoarenes with sodium perborate. The reaction of the iodoarenes with sodium perborate in acetic acid in the presence of triflic acid at 40-45 °C efficiently generates the corresponding (diacetoxyiodo)arenes in high yields within short time.
Alternative, easy preparation of (diacetoxyiodo)arenes from iodoarenes using potassium peroxodisulfate as the oxidant

An easy, safe and effective method for preparing (diacetoxyiodo)arenes [ArI(OAc)2], from iodoarenes is presented in this paper, using potassium peroxodisulfate as the oxidant. This procedure avoids the use of high temperature and severe reaction conditions. The reaction of the iodoarenes with potassium peroxodisulfate in acetic acid in the presence of concentrated sulfuric acid or trifluoromethane sulfonic acid at room temperature, efficiently generates the corresponding (diacetoxyiodo)arenes in high yield in a short reaction time.

Sodium perborate in acetic acid is an effective reagent for the oxidation of aromatic aldehydes to carboxylic acids, iodoarenes to (diacetoxyiodo)arenes, azines to N-oxides, and various types of sulfur heterocycles to S,S-dioxides.Nitriles are unaffected by the reagent in acetic acid, but undergo smooth hydration to amides when aqueous methanol is employed as solvent.
