Abstract
The mechanism of Ph/X exchange in reactions involving SnPh(n)Bu3 and [AuXL] complexes switches dramatically from the usual concerted mechanism involving Ar/X mixed bridges when X = Cl, to an unexpected oxidative addition/reductive elimination pathway via an Au(III) intermediate when X = vinyl.
