Treatment of 2-arylethylmagnesium bromides, prepared from 2-arylethyl bromides and magnesium, with aromatic nitriles, followed by reaction with water and then with N-iodosuccinimide under irradiation with a tungsten lamp, provides 2-arylquinolines in good yields under transition-metal-free conditions. 2-Alkylquinolines could be also obtained in moderate yields.
