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