Catalytic Au(<scp>i</scp>)/Au(<scp>iii</scp>) arylation with the hemilabile MeDalphos ligand: unusual selectivity for electron-rich iodoarenes and efficient application to indoles

Abstract

The ability of the MeDalphos ligand to trigger oxidative addition of iodoarenes preferentially electron-rich, to gold has been thoroughly studied and exploited to develop an efficient Au(<sc>i</sc>)/Au(<sc>iii</sc>)-catalysed C3-arylation of indoles.
