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

摘要

A new methodology for the direct C-H auration of electron-deficient arenes and heteroarenes with simple bases and readily available [Au(PR3)CI] 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.
