Oxidation of bis(perfluoroethyl) diselenide by antimony pentafluoride and by the dioxygen (1+) cation. Evidence for the novel cations [{Se(C2F5)}3]+ and [{Se(C2F5)}4n]2n+
Abstract
Bis(perfluoroethyl) diselenide is oxidized by both SbF5 and [O2][Sb2F11] to give orange or wine-red products, under appropriate conditions. These products are formulated as the [Sb2F11]– salts of the cations [{Se(C2F5)}3]+ and [{Se(C2F5)}4n]2n+, where n is probably equal to 1.
