Homogeneous gold catalysis has emerged as a powerful method for activating hydrocarbon double and triple bonds. Recent developments in the synthesis of organometallic intermediates have revealed exciting new details about mechanism and structure activity relationships. Central to these studies are the structure and reactivity of gold pi-complexes. Isolation of such complexes has depended predominantly on the presence of strong donor ligands (N-heterocyclic carbenes (NHC) and simple ligands of the Buchwald type such as Johnphos), while pi-complexes with triarylphosphine ligands or electronically differentiated biarylphosphine ligands are more sensitive to decomposition or have been largely unexplored. As such, correlating pi-complex structure with overall reactivity trends has remained difficult for a number of commonly used ligand types. In addition to reporting on the structural characterization of a series of new gold complexes with electron deficient aryl phosphine ligands, electronically differentiated or nitrogen appended alkyl phosphines, preliminary studies on the impact on stability and mechanism will also be presented.<br/>
