In the presence of Ru(phen)(3)Cl-2 or fac-Ir(ppy)(3) under visible-light irradiation, the addition of fluorinated radicals to N-arylacrylamides followed by an intramolecular cyano group insertion cascade cyclization process produced trifluoroalkyl or difluoroalkyl phenanthridine derivatives in moderate to good yields. Three easily available fluoroalkylated reagents CF3SO2Cl, BrCF2CO2Et and BrCF2PO(OEt)(2) were used as the sources of fluorinated radicals.
