The substitution of hypervalently bonded fluorine atoms in C 6F5IF4 was performed with C6F 5BF2 and resulted in the new salt [(C6F 5)2IF2][BF4]. The iodonium(V) salt was characterized by multi-NMR and Raman spectroscopy and X-ray crystal structure analysis. The fluorinating ability of the new electrophilic cation [(C6F5)2IF2]+ was exemplified in reactions with monovalent iodine compounds (C6F 5I, p-FC6H4I, and I2) and with electron-poor tri(organyl)pnictanes ER3 (E = P, As, Sb, Bi; R = C6F5). In a heterogeneous reaction with CsF in MeCN the [(C6F5)2IF2]+ cation forms the dinuclear [{(C6F5)2IF 2}2F]+ cation.
Stabilization of homopolyatomic cations of iodine in anhydrous hydrogen fluoride
Besida, John,O'Donnell, Thomas A.

Sodium fluoride and the Lewis acids NbF5, TaF5, and SbF5 have been used to fix precisely the levels of basicity and acidity in the solvent anhydrous HF in order to establish the acidity thresholds above which the cations I5+, I3+, and I2+ can be generated in solution. Addition of an excess of the base F- causes disproportionation of each of the cations to I2 and IF5. When these disproportionation products are dissolved in HF and the acidity level is adjusted appropriately, the individual cations can be generated. It is shown that the level of acidity is the principal determinant of the nature of the iodine cations generated in HF.
