A metal-free synthesis of primary aromatic amines from arylboronic acids affords structurally diverse primary arylamines in good chemical yields, including various halogenated primary anilines. The reaction is operationally simple, requires only a slight excess of aminating agent, proceeds under neutral or basic conditions, and can be scaled up to provide multigram quantities of anilines.
