Sulfonylfluorides are valuable synthetic motifs for a variety of applications, among which sulfur(VI) fluoride exchange-based “click chemistry” is currently the most prominent. Consequently, the development of novel and efficient synthetic methods to access these functional groups is of great interest. Herein, we report a mild and environmentally benign electrochemical approach to prepare sulfonyl

We report an inexpensive, thermally stable deoxyfluorination reagent that fluorinates a broad range Of alcohols without substantial formation of elimination side products. This combination of selectivity; safety, and economic viability enables,deoxyfluorination on preparatory scale. We employ the [F-18]-labeled reagent in the first example of a no-carrier-added deoxy-radiofluorination:
