trimethylsilyl derivatives. Cycloaromatization of these halogenated enediynes leads to the otherwise difficult to prepare 2,3-dibromoarenes in good yield. Alkynylation of the resulting haloaromatic compound regenerates the soluble enediyne system, homologated by one aromatic ring. This iterative methodology can be terminated by the cycloaromatization of the unsubstituted enediyne, providing the simple acene
[反应:见正文]简单的双(溴乙炔基)亚芳基二炔很容易通过相应三甲基甲硅烷基衍生物的脱甲硅烷基卤化反应制得。这些卤代二炔的芳环芳香化导致否则难以以高收率制备2,3-二溴芳烃。所得卤代芳族化合物的炔基化可再生可溶的二炔体系,该体系被一个芳香环所同源。该迭代方法可以通过未取代的二炔的环芳构化来终止,从而提供简单的并苯烃。
