AB By combining kinetic experiments, theoretical calculationsand microkinetic modelling, we show that the Pf/Rf (C6F5/C6Cl2F3)exchange between [AuPf(AsPh3)] and trans-[RhRf(CO)(AsPh3)2]does not occur through the typical concerted Pf/Rf transmetalationvia electron deficient double bridges. Instead, it involves asymmetricoxidative insertion of the RhI complex into the (Ph3As)Au–Pf bondproducing a [(Ph3As)Au–RhPfRf(CO)(AsPh3)2] intermediate, followedby isomerization and reductive elimination of [AuRf(AsPh3)].Interesting differences are found between the LAu–Ar asymmetricoxidative insertion and the classical oxidative addition process of H2to Vaska's complexes.
