Abstract

Friedel–Crafts reaction is widely used for the C–C bond forming reaction to enable the direct connection of electron-rich arenes to electron-deficient olefins with high regioselectivity. Herein, a highly efficient, metal-free, and environmentally benign F–C strategy of electron-rich arenes with N-arylmaleimides has been developed for the construction of 3-arylsuccinimides in the presence of a green reagent methanesulfonic acid under mild reaction conditions. This highly facile and high-yielding protocol has compatibility with different electron-rich arenes.
