One-pot preparations of diaryliodonium bromides from iodoarenes and arenes, with sodium perborate as the oxidant

Kryska, Anna,Skulski, Lech

, p. 875 - 880 (2001)

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.
