CF Bond Activation with an Apparently Benign Ethynyl Dithiocarbamate, and Subsequent Fluoride Transfer Reactions

F-act finding mission: Selective activation of the para C-F bonds of perfluorinated aromatic derivatives was achieved with a simple ethynyl dithiocarbamate. The resulting adducts can be used as non-ionic, anhydrous fluoride transfer reagents towards various electrophiles (see scheme).
