substitution of hypervalently bonded fluorine atoms in C6F5IF4 was performed with C6F5BF2 and resulted in the new salt [(C6F5)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 (C6F5I, p-FC6H4I
