An efficient protocol for C-H condensation of hypervalent iodine compounds with arenes in fluoroalcs. was applied to the recyclable preparation of mesityl iodonium(III) salts. The electrophilicities of [hydroxy(tosyloxy)iodo]mesitylene [MesI(OH)OTs] and iodomesitylene diacetate [MesI(OAc)2] were suitably enhanced in 2,2,2-trifluoroethanol. A series of nucleophilic aromatic compounds reacted smoothly with MesI(OH)OTs and MesI(OAc)2 or in-situ hypervalent iodine(III) species, generated from iodomesitylene, to provide the target mesityl iodonium(III) salts in good yields at room temperature with broad functional group tolerance. This C-H condensation strategy merits high para-regioselectivities during the diaryliodonium(III) salt formation, but the major limitation in the case of low-reactive aromatic substrates is byproduct formation resulting from the self-condensation of the nucleophilic mesitylene ring in MesI(OH)OTs and MesI(OAc)2.
