Secondary Phosphine Oxide-Gold(I) Complexes and Their First Application in Catalysis
Résumé
A series of new secondary phosphine oxide (SPO)-gold(1) complexes have been synthesized and characterized by X-ray crystallography. Complexes exhibited dimeric structures interconnected by O-H center dot center dot center dot Cl hydrogen bonds. Their first use in homogeneous catalysis is reported and suggests a broad field of application in prototypical enyne cycloisomerization and hydroxy- and methoxycyclization reactions.
