The direct metal-free borylation of diaryliodonium salts with diboron reagents is now demonstrated to be a feasible process toward formation of aryl boronic esters without any additive or catalysts, and it can be extended to a two-step C-C coupling of both aryl groups of the initial diaryliodonium reagent.
Synthesis of some n-aryl α-Amino acids using diaryliodonium salts

experimental part, p. 1227 - 1236 (2012/09/22)
Bis[(3'-methoxycarbonyl)phenyl]iodonium bromide (4a), bis (4'-methoxyphenyl)iodonium iodide (4b) and bis (4'-acetamidophenyl)iodonium iodide (4c) were employed for the first time in the arylation of α-amino acid methyl esters. Yields of the synthesised products 5, 6 and 7 were good to high. These were then hydrolyzed to the corresponding N-aryl α-amino acids 8 and 9. The chiral integrity of the amino acids was maintained throughout the reaction sequence as confirmed by the synthesis of chiral tripeptide 10 and dipeptides 11. The structures of the new compounds were confirmed by IR, 1H and 13C NMR in addition to CHN microanalysis or high resolution mass spectrometry.
Facile syntheses of symmetrical diaryliodonium salts from various arenes, with sodium metaperiodate as the coupling reagent in acidic media
Kraszkiewicz, Lukasz,Skulski, Lech
experimental part, p. 2373 - 2380 (2009/04/14)
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.
