ABSTRACT:
[Hydroxy(organosulfonyloxy)iodo]arenes are synthesized in neutral organic solvents by the reaction of ring-subsituted [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.
