A dearomative trifluoromethylative aminocarbonylation of arenesviabifunctionalcoordination to chromium has been firstly developed for amide construction, which expands the boundary of aminocarbonylations from conventional C=C bond substrates to arenes. Furthermore, a switchable 1,2-difunctionalization of arene C−H bonds and concise synthesis of amide-type drug analogs were successfully achieved
