Graphical Abstract

CS2 jumps in: CF bond formation occurs by reactions of the fluorido complexes trans-[Ir(ArF)(F)(H)(PiPr3)2] (ArF=4-C5NF4; see scheme) with CS2 to form the fluorodithiocarbonato species trans-[Ir(ArF)(H)(κ2-(S,S)-S2CF)(PiPr3)2]. DFT studies suggest an unprecedented concerted metathesis-like mechanism for the CF bond-formation step in which CS2 inserts into the IrF bond.
