The anionic trifluoromethylgold(I) derivatives [CFAuX], which have been prepared and isolated as their [PPh] salts in good yield, undergo thermally induced difluorocarbene extrusion in the gas phase, giving rise to the mixed gold(I) fluorohalide complexes [F−Au−X] (X=Cl, Br, I). These triatomic species have been detected by tandem mass spectrometry (MS2) experiments and their properties have been analyzed by DFT methods. The CF extrusion mechanism from the Au−CF moiety serves as a model for the CF insertion into the Au−F bond, since both reactivity channels are connected by the microreversibility principle.
