In this manuscript we describe the oxidative fluorination of aryl phosphorothiolates to access Ar-SF4Cl compounds. These compounds serve as precursors for the highly coveted Ar-SF5 compounds. The use of phosphorothiolates as starting materials permits access to Ar-SF4Cl from a wide variety of available starting materials, namely boronic acids, diazonium salts, aryl iodides, thiophenols, or simple arenes. The protocol has been demonstrated for 10 examples and showed good tolerance to various functional groups. Finally, we demonstrated that AgBF4 can be used as a fluorinating agent, affording good yields of an Ar-SF5.

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
