A fluorosulfuryl imidazolium salt delivers an “F−SO 2 +” group to phenols and amines with phenomenal efficiency. In their Communication on page 2605 ff., K. B. Sharpless, J. Dong, and co‐workers present the practical, mole‐scale synthesis of this stable, powerful reagent, which provides clickable RNHSO 2 F, dramatically expands the scope of SuFEx products, and constitutes a complementary alternative to SO 2 F 2 gas delivery.
