“…Gold halides have attracted considerable interest and especially the fluorides still need further exploration [99]. A particular challenge has been the gold(I) fluoride AuF [100], whose first preparation employed neutralization of a mass-selected beam of the corresponding cation AuF + in a neutralization-re-ionization experiment (NRMS [101]).…”

The homoleptic compound [PPh4][CF3AuCF3] cleanly undergoes photoinduced oxidative addition of CF3I to afford the organogold(III) derivative [PPh4][(CF3)3AuI] in good yield and under mild conditions. This compound provides a convenient entry to the chemistry of the perfluorinated (CF3)3Au fragment, the properties of which were analyzed with the aid of DFT methods and compared with those of the homologous non‐fluorinated (CH3)3Au moiety. It was found that reductive elimination of CX3−CX3 in the former (X=F) requires a much higher energy barrier than in the latter (X=H) and is therefore considerably less favored. This can be considered as one of the main features underlying the significantly higher stability associated to the (CF3)3Au fragment and its derivatives. This unsaturated, 14‐electron species can be stabilized by coordination of any of the halide ligands, including fluoride. In fact, the whole series of anionic [PPh4][(CF3)3AuX] complexes (X=F, Cl, Br, I, CN) has now been isolated and conveniently characterized. Evidence for intermolecular decomposition pathways upon thermolysis in the condensed phase is presented.

“…Compound 2 can be synthesized selectively by reacting two or more equivalents of SIMes with [NMe 4 ][AuF 4 ]. [30] Hence,r apid decomposition of [Au I F 2 ] À with reduction of the gold atom and nonselective generation of fluorination products can be assumed and would be consistent with previous studies. [26] Theh ydrogen difluoride anion could be excluded as the counterion by 19 FNMR, Raman, and IR spectroscopy (SI Figures S-11, S-15, and S-16).…”

Stabilization of Lewis Acidic AuF₃ as an N‐Heterocyclic Carbene Complex: Preparation and Characterization of [AuF₃(SIMes)]

Two different reaction routes are described to access the unprecedented trifluoridoorganogold(III) complex [AuF (SIMes)]. The compound bears the N-heterocyclic carbene SIMes (1,3-bis(2,4,6-trimethylphenyl)-4,5-dihydroimidazol-2-ylidene) as a ligand for a molecular Lewis acidic AuF unit and was characterized by NMR spectroscopy as well as X-ray crystallography. Apart from the use of a [AuF ] salt as precursor, the strong oxidizing compound AuF can be employed neat as starting material. The reaction proceeded even in organic solvents in the presence of SIMes as the ligand precursor. Decomposition reactions with the solvent can, therefore, be prevented by using this strategy.
