Abstract

Abstract The reaction of arenes with elemental iodine, acetic acid, and potassium μ-peroxo-hexaoxodisulfate (K2S2O8) in the presence of concentrated sulfuric acid, efficiently generated the corresponding (diacetoxyiodo)arenes in good yields. Diaryliodonium triflates were directly synthesized by reaction of arenes with elemental iodine in good yields by using K2S2O8, AcOH, and TfOH. Diaryliodonium tosylates were also prepared from arenes and elemental iodine by using K2S2O8, AcOH, H2SO4, and TsOH. The procedure involved mild conditions and a straightforward one-pot synthesis.
