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.
