Diphenyl‐ and dimesityl‐phosphanyl‐substituted 3,3,4,4,5,5‐hexafluorocyclopentenyl‐gold(I) dimers – syntheses and solid‐state structures

1,2-Dichloro-3,3,4,4,5,5-hexafluorocyclopentene (F 6 cypCl 2 ) was functionalized with diphenyl- and dimesitylphosphanyl groups by a salt-elimination reaction of the respecttive chlorophosphane (PPh Cl, PMes Cl) in situ generated lithiated F cyp(Li)Cl. cyp(PR )Cl (R = Ph, Mes) functionalised again to obtain corresponding trimethylstannyl substituted compounds )(SnMe 3 Mes). These tin-precursors were used tin-gold exchange reactions synthesize dinuclear gold(I) dimers [F )Au] For mesityl compound, phosphanegold chloride adduct cyp(PMes AuCl)(SnMe ), intermediate reaction, could also be isolated. All characterized multinuclear NMR spectroscopy X-ray diffraction experiments.
