General synthesis of (diacetoxyiodo)arenes 8: Iodoarene 1 (1.0 equiv) was added to a solution of NaOCl5H2O (1.2 equiv) in concentrated AcOH [0.6 M] in a round bottom flask. The solution was vigorously stirred for 30 min followed by addition of CH2Cl2 and toluene (1:1, 0.01 M) to dissolve the product. The resulting undissolved solid was filtered off and the solvent was evaporated under reduced pressure. Product 8 was precipitated in petroleum ether and isolated by filtration.
