Diareno[a,e]cyclooctatetraenes find widespread applications as building blocks, ligands, and responsive cores in topologically switchable materials. However, current synthetic methods to these structures suffer from low yields or operational disadvantages. Here, we describe a practical three-step approach to diareno[a,e]cyclooctatetraenes using an efficient copper(I) catalyzed double decarboxylation
二芳基[ a , e ]环辛四烯在拓扑可切换材料中作为构件、配体和响应核具有广泛的应用。然而,目前这些结构的合成方法存在产率低或操作上的缺点。在这里,我们描述了一种实用的三步法制备二芳基 [ a , e ] 环辛四烯,使用高效的铜 (I) 催化双脱羧作为关键步骤。该序列依赖于廉价和丰富的试剂,很容易大规模进行,并且还适用于扩展这类有趣结构的效用的不对称衍生物。
