Unless otherwise stated, all manipulations were performed using standard Schlenk techniques under dry nitrogen or using Saffron Scientific or MBRAUN glove boxes. Nitrogen was purified by passing through columns of supported P2O5 with moisture indicator and activated 4 Å molecular sieves. Anhydrous solvents were freshly distilled from appropriate drying agents. (C^N^C)AuOH (30 ), (C^N^C)Au(OAcF) (30 ), [(C^N^C)Au]2O (27 ), (C^N^C)AuH (25 ), [(C^N^C)Au]2 (25 ), [(C^N^C)Au(η2-C2H4)][B(C6F5)3(OAcF)] (26 ), and B(C6F5)3 (34 ) were prepared using literature methods. [Ph3C][PF6] (Sigma) was used as purchased. Natural abundance CO (BOC) and 13CO (Euriso-Top) were used as purchased or dried before use passing through columns with activated 4 Å molecular sieves.
1H, 13C{1H}, and 19F spectra were recorded using a Bruker Avance DPX-300 or a Bruker Avance DPX-500 spectrometer. Deuterated solvents were dried over CaH2, degassed by three freeze-pump-thaw cycles, and stored on 4 Å molecular sieves before use. 1H NMR spectra (300.13 MHz) were referenced to the residual protons of the deuterated solvent used. 13C{1H} NMR spectra (75.47 MHz) were referenced internally to the D-coupled 13C resonances of the NMR solvent. IR spectra were recorded using a Perkin Elmer Spectrum 65 FT-IR spectrometer with a diamond attenuated total reflectance attachment or using liquid cells with KBr plates.
