The [Cu]-catalyzed SN AR reactions: direct amination of electron deficient aryl halides with sodium azide and the synthesis of arylthioethers under Cu (II)–ascorbate …
A one pot [Cu]-promoted SNAr reaction of electron-deficient halobenzenes with sodium azide and the reduction of the intermediate aryl azides under the same Cu (II)–ascorbate redox conditions leading to anilines has been documented. Control experiments revealed
