Reaction of Arenes with Iodine in the Presence of Potassium Peroxodisulfate in Trifluoroacetic Acid. Direct and Simple Synthesis of Diaryliodonium Triflates
Diaryliodonium triflates have been directly prepared byreaction of arenes with elemental iodine in good yields byusing K2S2O8 and TFA, followed by treatment with NaOTf.This procedure avoids the use of high temperature and severereaction conditions.
