A transition metal-free C−N arylation of easily accessible tertiary anilines enabled by bifunctional arynes is described. The reaction proceeds via a tandem nucleophilic attack of anilines to arynes, followed by a Smiles-Truce rearrangement to furnish synthetically valuable and densely substituted biaryls. This protocol was further utilized for heterocyclic scaffolds, providing access to medium size
