Metal-Free SF Activation: A New SF -Based Reagent Enables Deoxyfluorination and Pentafluorosulfanylation Reactions.

The activation of SF , a potent greenhouse gas, under metal-free and visible light conditions is reported. Herein, mechanistic investigations including EPR spectroscopy, NMR studies and cyclic voltammetry allowed the rational design of a new fluorinating reagent which was synthesized from the 2-electron activation of SF with commercially available TDAE. This new SF -based reagent was efficiently employed for the deoxyfluorination of CO and the fluorinative desulfurization of CS allowing the formation of useful fluorinated amines.
