Making the SF5 Group More Accessible: A Gas-Reagent-Free Approach to Aryl Tetrafluoro-λ6-sulfanyl Chlorides

Modern pentafluorosulfanyl (SF5) chemistry has an Achilles heel: synthetic accessibility. Herein, we present the first approach to aryl-SF4Cl compounds (key intermediates in state-of-the-art aryl-SF5 synthesis) that overco

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.

An improved method for the fluorination of arylsulfur chlorotetrafluorides to arylsulfur pentafluorides

A new method for the fluorination of arylsulfur chlorotetrafluorides to arylsulfur pentafluorides is described. The reaction is promoted by hydrogen fluoride generated from potassium hydrogen fluoride and trifluoroacetic acid which also serves as a solvent. The reaction is performed under mild conditions and uses substochiometric amounts of potassium hydrogen fluorides in certain cases. Recovery and reuse of trifluoroacetic acid was successfully demonstrated which makes this method safe, simple to use, and atom- and cost-effective.
