Abstract

Sulfonyl fluorides and sulfamoyl fluorides, as the most significant species among sulfur(VI) fluorides, have garnered considerable attention in various fields, including organic synthesis, materials science, chemical biology, and drug discovery. Fluorosulfonyl-containing radical reagents have unique reactivity and exhibit notable advantages in constructing complex organic molecules, achieving selective functional group transformations. This short review provides a detailed introduction to the diverse applications of fluorosulfonyl-containing radical reagents in organic synthesis, such as C–H bond functionalizations, difunctionalization of olefins, and tandem reactions, highlighting their crucial roles in synthesizing complex organic molecules
