[(C6F5)2if2][BF4], the first salt with the electrophilic cation [(C6F5) 2if2]+: Synthesis, reactivity, and structure

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.
