Stoichiometric quantities of trifluoroacetic acid and trimethoxybenzene can be used as the counteranion and auxiliary precursors for a direct synthesis of aryl(2,4,6-trimethoxyphenyl)iodonium trifluoroacetate salts from aryl iodides under oxidizing conditions. The reaction occurs at mild temperature, is broad in scope, and does not require a separate anion exchange step to install the trifluoroacetate group.
