摘要
Friedel-Crafts alkylation of various arenes/heteroarenes to beta-nitrostyrenes mediated by aluminum chloride is described. The interesting feature of this methodology pertain the formation of different products by tuning the reaction temperature. alpha-Arylated nitroalkanes were formed predominately at -78 degrees C, whereas alpha-arylated hydroximoyl chlorides were obtained at room temperature without any side products in high yields.
