Facile syntheses of symmetrical diaryliodonium salts from various arenes, with sodium metaperiodate as the coupling reagent in acidic media
Kraszkiewicz, Lukasz,Skulski, Lech
, p. 2373 - 2380 (2008)
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.

A facile synthesis of diaryliodonium salts utilizing Oxone as versatile and cheap oxidant has been developed. This method shows wide applicability and can be used for the preparation of iodonium salts containing electron-donating or electron-withdrawing groups in good yields. In addition, this procedure can be applied to the preparation of symmetric iodonium salts directly from arenes via a one-pot iodination-oxidation sequence.
