Title: Two special pathways to perfluoroaryl iodonium salts: the migration of the nucleophilic aryl group in C6F5IO and the electrophilic arylation of C6F5I with [C6F5Xe]+ salts
Abstract: Two theoretically interesting pathways to the perfluorinated diaryliodonium cation [(C 6 F 5 ) 2 I] + are described: the electrophilic arylation of C 6 F 5 I by [C 6 F 5 Xe] + salts and the nucleophilic migration of a C 6 F 5 group in the iodosyl compound C 6 F 5 IO.The first method allowed also the arylation of C 6 F 5 Br, but failed in the case of C 6 F 5 Cl.Furthermore, the protodeiodination of C 6 F 5 IO and [(C 6 F 5 ) 2 I] + in alkaline medium was investigated.
