This synthesis produces sulfonimidoyl and sulfondiimidoyl fluorides using sulfenamides, indicating diverse SuFEx applications.
Comprehensive Summary As the aza‐isosteres of sulfonyl fluorides, sulfonimidoyl‐ and sulfondiimidoyl fluorides are versatile and robust SuFEx linkage agents, yet with limited synthetic accessibility. Herein, we report the straightforward, divergent synthesis of sulfonimidoyl‐ and sulfondiimidoyl fluorides from bench‐stable, readily available sulfenamides and Selectfluor. The obtained sulfonyldiiminyl fluorides readily underwent versatile SuFEx reactions with various nucleophiles to afford various biologically interesting sulfondiimidoyl derivatives.
