Iodine difluondes, preparation

Polymer-bound phenyliodine difluoride, which also has been used as a reagent to add fluorine to alkenes, can be prepared by the addition of xenon difluonde to the polymer [134, 135 136] Methyl iodide is converted to trifluoro methyliodine difluonde by treatment with fluorine at -110 °C [137] Perfluoro-alkyliodine tetrafluondes could be synthesized from the perfluoroalkyliodme difluorides and fluorine 38 or chlorine tnfluonde [759] Perfluoroalkyl [140] and perfluoroary 1 [141] iodides are oxidized to the corresponding iodine difluondes by chlorine trifluoride.
