Synthesis, Characterization, and Reaction of Crown Ether Complexes of Aqua(hydroxy)(aryl)iodonium Ions

Abstract

Crown-compound complexation through secondary hypervalent I⋅⋅⋅O bonding interactions enables stabilization of an aqua(hydroxy)(phenyl)iodonium ion. The resulting aqua complex 1 is stable in the solid state as well as in solution and serves as a versatile oxidizing agent, especially in water. Tf=trifluoromethanesulfonyl.
