Aryne arylation: A new method of direct arylation 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.
芳基芳基化:据报道苯胺底物有一种直接芳基化的新方法。该反应使用苯炔在温和条件下合成各种氨基联芳基(参见方案),无需化学计量的金属化或过渡金属催化。涉及烯键机制,并相对于金属介导的过程传达了出色的官能团耐受性。
