Abstract
AbstractSulfonyl 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.magnified image
