Photoinduced electron-transfer reaction of difluorodiiodomethane with aza-aromatic compounds and enamines

Irradiation of difluorodiiodomethane 1 with pyrroles, indole and imidazoles in dimethylformamide gives the Corresponding trifluoromethylated products, whereas irradiation with enamines results in 2-trifluoromethyl ketones. A photoinduced electron-transfer mechanism is proposed.
