The reaction of xenon bis-pentafluoroseleniumoxide, Xe(OSeF5)5, with the haloolefins, CF2=CF2, CF3CF=CF2, CF2=CFCl, and CF2=CFH, results in the low to moderate yield addition of two SeF5O- groups to the double bond.These are the first examples of this type of addition.From c-C5F8 and the above olefins these same reactions also gave as products, C2F5OSeF5, n-C3F7OSeF5, c-C5F9OSeF5, and SeF5OCF2COCl in higher yields than the bis SeF5O- compounds.Surprisingly, those olefins capable of forming thermally stable epoxides, i.e.C3F6 and c-C5F8, were found to produce significant yields of the corresponding epoxides as a by-product in these reactions, while the remaining olefins gave significant amounts of acid fluorides instead.Characterizing data are presented for all of these new RfOSeF5 compounds.
