By combining kinetic experiments, theoretical calculations, and microkinetic modeling, we show that Pf/Rf (C6F5/C6Cl2F3) exchange between [AuPf(AsPh3)] and trans-[RhRf(CO)(AsPh3)2] does not occur by typical concerted Pf/Rf transmetalation via electron-deficient double bridges. Instead, it involves asymmetric oxidative insertion of the RhI complex into the (Ph3As)Au?Pf bond to produce a [(Ph3As)Au?RhPfRf(CO)(AsPh3)2] intermediate, followed by isomerization and reductive elimination of [AuRf(AsPh3)]. Interesting differences were found between the LAu?Ar asymmetric oxidative insertion and the classical oxidative addition process of H2 to Vaska complexes.
Strong metallophilic interactions in the palladium arylation by gold aryls

It's the second step that counts: Arylation of Pd by Au takes place through transition states and intermediates featuring strong Au/Pd metallophilic interactions (see picture). However, the aryl transfer from [AuArL] to [PdArClL2] is thermodyna
