Abstract

The treatment of [(diacetoxy)iodo]benzene with sodium bisulfate leads to the formation of oligomeric cationic species resulting from self-assembly of hydroxy(phenyl)iodonium ions, [PhlOH] +, in an aqueous acidic media. Depending on the Phl(OAc) 2:NaHSO 4 ratio, three new oligomeric products have been isolated and characterized by X-ray crystallography. The treatment of 5 equiv of Phl(OAc) 2 with 1 equiv of NaHSO 4-H 2O affords the previously unknown μ-oxo-[bis(acetoxy)iodo]benzene,Phl(OAc)OI(OAc)Ph, which was structurally characterized by X-ray crystallography. In the solid-state, this μ-oxo product forms an isolated diamond-core dimeric structure with pentagonal-planar iodine centers. The interaction of Phl(OAc) 2 with 1 equiv of NaHSO 4· H 2O affords a solid-state polymeric phenyliodine(lll) sulfate, [(PhlO) 3 · SO 3]n, in which bis(μ-oxo)triiodanyl dication repeat units are linked by sulfate anions. Three of these neighboring polymeric chains form pseudo triple-helix supramolecular structure, which translates along crystal-lographic b-axis. The reaction of Phl(OAc) 2 with 3 equiv of NaHSO 4 · H 2O results in the formation of a tetrameric phenyliodine(lll) sulfate, Phl(OH)OSO 2O(Ph)IOI(Ph)OSO 2OI(OH)Ph, the solid state structure of which consists of μ-oxodiiodanyl dicationic species linked by sulfate anions to the terminal hydroxy(phenyl)iodonium groups. The pseudo double-helix structure of this compound formed by the strong intermolecular interactions between two neighbor μ-oxodiiodanyl dicationic fragments and four (per pseudo helix dimer) areas of sulfate anions to the terminal hydroxy(phenyl)iodonium groups interactions.
