A mild and facile method for preparing highly functionalized pyrrolo[1,2‐a]quinoxalines and other nitrogen‐rich heterocycles, each containing a quinoxaline core or an analogue thereof, has been developed. The novel method features a visible‐light‐induced decarboxylative radical coupling of ortho‐substituted arylisocyanides and radicals generated from phenyliodine(III) dicarboxylate reagents and exhibits
