The cycloaromatization of easily-prepared arenediynes is an efficient route to fused aromatic systems, but the requirement of very high temperatures to induce this reaction limits both scal- ability and generality. We demonstrate that cycloaromatization can be induced by addition of a radical species to an arenediyne unit. Tethering this radical to the enediyne leads to the formation of larg- er fused
易于制备的芳烃的环芳构化是稠合芳烃系统的有效途径,但需要非常高的温度来诱导该反应限制了可扩展性和通用性。我们证明可以通过向芳二炔单元添加自由基物种来诱导环芳构化。将该自由基束缚在烯二炔上会导致在一个步骤中形成更大的稠合系统,例如荧蒽和苯乙炔。
