A visible‐light‐induced and copper‐promoted perfluoroalkylation of benzamides was successfully developed under the assistance of an 8‐aminoquinoline directing group. It provides a straightforward method for the synthesis of ortho‐perfluoroalkyl‐substituted benzoic acid derivatives. The reaction employs a cheap organic dye eosin Y as the photoredox catalyst and is run under the irradiation of a 26 W fluorescent LED light bulb. 相似文献
