Sulfonyl fluorides are useful motifs for a wide range of applications in organic synthesis including sulfur (VI) fluoride exchange-based “click chemistry.” Herein, a visible-light-mediated synthesis of sulfonyl fluorides from arylazo sulfones is described. In the present study, K2S2O5 and N-fluorobenzenesulfonimide (NFSI) were used as the sulfonyl source and fluorinating agent, respectively, for visible-light-mediated fluorosulfonylation of arylazo sulfones to prepare various sulfonyl fluorides in 60–85% yield. This protocol is a synthetic approach to provide useful sulfonyl fluoride structures at room temperature. (Figure presented.).

Syntheses of 1,3-difluorobenzene and 2,6-difluorotoluene are described via chlorosulfonation, catalytic Halex-fluorination, and desulfination of 1,3-dichlorobenzene and 2,6-dichlorotoluene.

Halogen-exchange of chloroaryl sulfonylchloride derivatives with spray-dried potassium fluoride was found to proceed efficiently by employing tetraphenylphosphonium bromide as a catalyst.Subsequent desulfonylation of the fluoroaryl sulfonyl derivatives readily afforded fluoroaromatics under acidic condition.

, (2008/06/13)
Fluorobenzenesulfonyl fluorides are prepared by chlorine/fluorine exchange fluorinating a chlorobenzenesulfonyl fluoride with an alkali metal fluoride, in a aprotic polar solvent and at a temperature ranging from about 100° C. to about 240° C.
