Aryne arylation: A new method of directarylation is reported for aniline substrates. The reaction uses benzyne to synthesize a variety of aminobiaryls under mild conditions (see scheme), requiring no stoichiometric metalation or transition‐metal catalysis. An ene mechanism is implicated, and conveys excellent functional group tolerance relative to metal‐mediated processes.
