Using commercially available Ph3PAuCl and readily prepared, benign arylsilanes, a gold-catalyzed oxyarylation of alkenes proceeds smoothly in air. The oxidant, Selectfluor, not only facilitates entry to the Au(I/III) manifold but also provides a fluoride anion for silane activation, thereby avoiding the need for addition of a stoichiometric base.
