Efficient Synthesis of 2-Fluoromethylated Quinolines via Copper-Catalyzed Alkynylation and Cyclization of Fluorinated Imidoyl Iodides

2-Fluoromethylated quinolines were synthesized through the reaction of N-aryl-fluorinated imidoyl iodides with terminal alkynes in good yields by the catalysis of copper(I) iodide (CuI) alone.
