One-pot preparations of diaryliodonium bromides from iodoarenes and arenes, with sodium perborate as the oxidant
Kryska, Anna,Skulski, Lech
, p. 875 - 880 (2007/10/03)
This paper reports a one-pot synthesis of the title bromides from both activated and deactivated iodoarenes which are first oxidized with anhydrous NaBO3·H2O/Ac2O/conc.H2SO 4 liquid mixtures, then coupled in situ with benzene and activated arenes and, finally, precipitated out with a KBr solution; this method is easy, cheap, safe and fairly effective.
A short-cut synthesis of diaryliodonium bromides followed by oxidative anion metatheses

This paper reports a one-pot synthesis of the title bromides (in 20-88% crude yields) from iodoarenes oxidized with the CrO3/AcOH/Ac2O/H2SO4 liquid mixture, then coupled in situ with arenes and, finally, precipitated out with a KBr solution. Similarly, diaryliodonium perchlorates and iodides are obtained in 40-89% crude yields. Oxidative anion metatheses in the crude title bromides produce the respective pure diaryliodonium tetrafluoroborates, tosylates, trifluoroacetates, hydrosulfates, nitrates, and chlorides in 57-80% yields. These new preparative procedures are easier and shorter than many earlier methods.
