A silver-free system for the direct C–H auration of arenes and heteroarenes from gold chloride complexes

Abstract

A new methodology for the direct C–H auration of electron-deficient arenes and heteroarenes with simple bases and readily available [Au(PR3)Cl] complexes is described. This system allows the preparation of a wide scope of aryl–Au(I) compounds without the need for using Ag(I) additives or preparing and isolating basic Au(I) hydroxide complexes.
