, p. 9903 - 9905 (2006)
Diaryliodonium triflates have been directly prepared by reaction of arenes with elemental iodine in good yields by using K2S2O 8 and TFA, followed by treatment with NaOTf. This procedure avoids the use of high temperature

A new synthetic method was developed for the N-arylation of pyrazoles using diaryliodonium salts. The transformation does not require any transition-metal catalyst and provides the desired N-arylpyrazoles rapidly under mild reaction condition in the presence of aqueous ammonia solution as a mild base without the use of inert atmosphere. The chemoselectivity of unsymmetric diaryliodonium salts was also explored with large number of examples.
