Gold(I) Fluorohalides: Theory and Experiment
The anionic trifluoromethylgold(I) derivatives [CF3AuX]â, which have been prepared and isolated as their [PPh4]+ salts in good yield, undergo thermally induced difluorocarbene extrusion in the gas phase, giving rise to the mixed gold(I) fluorohalide complexes [FâAuâX]â (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 CF2 extrusion mechanism from the AuâCF3 moiety serves as a model for the CF2 insertion into the AuâF bond, since both reactivity channels are connected by the microreversibility principle
