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:

We report the synthesis of sulfone iminium fluorides (SIFs), a reactive class of sulfur(VI) molecules. The synthesis is tolerant of a variety of substituents on the sulfur and nitrogen components. The SIF reagents were applied to the deoxyfluorination of alcohols and carboxylic acids, providing highyields of fluorinated products in 60 s at room temperature. The SIF reagents were then utilized in sulfur
