Pseudocyclic lodine V Compounds

Methyl-2-iodoxybenzoate can be further converted to the diacetate 243 or a similar bis(trifluoroacetate) by treatment with acetic anhydride or trifluoroacetic anhydride, respectively (2005JOC6484). A single-crystal X-ray diffraction analysis of methyl-2-[(diacetoxy)(oxo)iodo]benzoate 243 revealed a pseudo-benziodoxole structure with three relatively weak intramolecular I 0 interactions. Esters of 2-iodoxyisophthalic acid (e.g., 244) were prepared by the oxidation of the respective iodoarenes with dimethyl-dioxirane. An X-ray structural analysis of diisopropyl 2-iodoxyisophthalate 244 has demonstrated strong intramolecular interaction with the 

The soluble and stable pentavalent iodine N-(2-iodylphenyl)acylamides 252 with a pseudo-benziodoxazine structure have been synthesized in good 

Polymer-supported 2-iodophenol ethers have also been reported (2007JOC8149).
