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 [PdArClL 2 ] is thermodynamically disfavored and will not occur unless an irreversible ArAr coupling from [PdAr 2 L 2 ] follows.
