We report a new protocol to form pentafluorosulfanyl (hetero)arenes via chlorine-fluorine exchange of (hetero)aryl tetrafluorosulfanyl chlorides by AgBF4. The method enables access to electron-deficient pentafluorosulfanyl(hetero)arenes, which are targets that are difficult to synthesize. Two advantages of AgBF4 are its ease of handling and stability. This would be a general transformation protocol.
IF5 affects the final stage of the Cl-F exchange fluorination in the synthesis of pentafluoro-λ6-sulfanyl-pyridines, pyrimidines and benzenes with electron-withdrawing substituents

A difficult chlorine-fluorine (Cl-F) exchange fluorination reaction in the final stage of the preparation of pentafluoro-λ6-sulfanyl-(hetero)arenes having electron-withdrawing substituents has now been elucidated through the use of iodine pentafluoride. A major side-reaction of C-S bond cleavage was sufficiently inhibited by the potential interaction between F and I with a halogen bonding.
Ir-catalyzed preparation of SF5-substituted potassium aryl trifluoroborates via C-H borylation and their application in the Suzuki-Miyaura reaction
Joliton, Adrien,Carreira, Erick M.
, p. 5147 - 5149 (2013/11/06)
The preparation of new pentafluorosulfanyl-substituted potassium aryltrifluoroborates via Ir-catalyzed C-H borylation is reported. The utility of these novel building blocks was demonstrated in the Suzuki-Miyaura cross-coupling reaction, giving access to
