An easy, inexpensive, safe, and effective preparative procedure to obtain symmetrical diaryliodonium bromides (in 17-88% crude yields) from various arenes is presented in this paper. A novel method for the in situ preparation of iodosyl sulfate (Chretien's reagent) is given. Eleven exemplary crude diaryliodonium bromides were readily oxidatively metathesized with 40% aqueous tetrafluoroboric acid and 30% aqueous hydrogen peroxide (in boiling acetone, used both as a solvent and 'halogen scavenger') to give pure diaryliodonium tetrafluoroborates in 15-85% yields.
