PLATFORM UPDATE:
Herein, we report a new thionyl fluoride-based method that rapidly converts sulfinic acids into the corresponding sulfinyl fluorides in 62-97% yield. The unstable sulfinyl fluorides can be directly treated with chloramine-T to afford sulfonimidoyl fluorides, an important class of sulfur(VI)-fluoride exchange (SuFEx) hubs, in 56-92% isolated yields.
