Treatment of quinolines and isoquinolines with benzoyl peroxide in tertiary amides, such as N,N-dimethylacetamide, N,N-dimethylpropionamide, and N-acetylpyrrolidine, etc., under irradiation with a Hg lamp in the temperature range of 35 °C to 40 °C gave C–C-bonded quinolines and isoquinolines bearing amide groups with high regioselectivity in good to moderate yields, respectively, under transition-metal-free

the α-amidoalkylation of benzo-fused N-heteroaromatic bases has been performed in the presence of sodium persulfate as a free-radical source and terminal oxidant without using acids and transition metals. The desired α-amidoalkylated products have been obtained in high yields in relatively short reaction times compared with those generally reported at 50 and 80 °C. The biggest advantage of this new protocol
