The first one-pot synthesis of neutral and electron-rich [hydroxy(tosyloxy)iodo]arenes (HTIBs) from iodine and arenes is presented, thereby avoiding the need for expensive iodine(III) precursors. A large set of HTIBs, including a polyfluorinated analogue, can be obtained from the corresponding aryl iodide under the same conditions. The reaction proceeds under mild conditions, without excess reagents, and is fast and high-yielding. Together, the two presented routes give access to a wide range of HTIBs, which are useful reagents in a variety of synthetic transformations.
Composition and a process for the preparation of [hydroxy(organosulfonyloxy)iodo]arenes and their use in a regiospecific synthesis of diaryliodonium salts

[Hydroxy(organosulfonyloxy)iodo]arenes are synthesized in neutral organic solvents by the reaction of ring-substituted [hydroxy(organosulfonyloxy)iodo]benzenes with iodoarenes via ligand transfer. The produced compounds are reacted with (triorganosilyl) arenes or (trihalosilyl)arenes in neutral organic solvents to produce diaryliodonium salts. The diaryliodonium salt synthesis proceeds in regiospecific fashion, aryliodination occurring at the point of attachment of the silicon atom in the silylarenes.

Treatment of a variety of aryl iodides with benzene (1) under mild conditions resulted in ligand transfer, and new arenes were obtained.However, with some substrates containing proximate functional groups cyclic iodonium salts and iodinanes resulted.The reaction between 1 and 2-iodothiophene took a distinctly different course.
