A photocatalytic tandem radical arylation/cyclization of N-arylacrylamides with diaryliodonium triflates at room temperature affords 3-(benzyl)oxindoles in moderate to good yields. The diaryliodonium triflates upon blue visible light irradiation in the presence of Ir(ppy)2(dtbbpy) ยท PF6 as the photocatalyst release aryl radicals which would add at the double bond of the acrylamide to initiate the cyclization involving the N-aryl substituent.
