WebNational Center for Biotechnology Information WebJan 1, 1993 · The resulting [I (OCOCF3)2] [OSO2R] is the reactive species which attacks pentafluorobenzene in an electrophilic manner to form I (C6F,) (OCOCF3)2. A repetition of this sequence, followed by a substitution of the trifluoroacetate group by the sulphonate group, finally yields [I (C6F5)2] [OSO2R].
