Iodine pentafluonde

Additions of halogen fluorides to the more electrophilic peifluonnated olefins generally require different conditions Reactions of iodine fluoride, generated in situ from iodine and iodine pentafluonde [62 102 103, 705] or iodine, hydrogen fluoride, and parapenodic acid [104], with fluorinated olefins (equations 8-10) are especially well studied because the perfluoroalkyl iodide products are useful precursors of surfactants and other fluorochemicals Somewhat higher temperatures are required compared with reactions with hydrocarbon olefins Additions of bromine fluoride, from bromine and bromine trifluonde, to perfluormated olefins are also known [106]...
