Generation of 4-polyfluoroaryl pyrrolo[1,2-a]quinolines via C-H bond activation

A novel and efficient preparation of 4-polyfluoroaryl pyrrolo[1,2-a]quinolines via a palladium-catalyzed reaction of 1-[2-(2,2-dibromoethenyl)phenyl]-1H-pyrrole with polyfluoroarene is described. This transformation is efficient, leading to the corresponding products in good yields.
