A series of highly substituted 2-perfluoroalkyl-3-iodoquinolines are prepared by two different methods in good to excellent yields under mild reaction conditions. The first method involves iodocyclization of perfluoroalkyl propargyl imines with I2-CAN. The second method involves iodocyclization of perfluoroalkyl propargyl amines using I2 and ICl. The perfluoroalkyl propargyl amines are prepared in
