Abstract
A [Ir(ppy)2(dtb-bpy)]PF6-catalyzed intramolecular radical cyclization of o-iodophenylacrylamides affording indolin-2-ones in moderate to excellent yields via 5-exo-trig radical cyclization under visible light is presented. This method provides new access to the synthesis of indolin-2-ones under mild reaction conditions.
