coupling partner. These polyaromatic structures are obtained in high yields, in 10 min at room temperature, with minimal waste generation (E‐factors as low as 1.5) and without the need for strict inert conditions, making this process highly efficient and practical in comparison to classical methods. As illustration, several key intermediates of widely used BINOL‐derived structures are readily prepared
介绍了芳基卤化物的均偶联和芳基卤化物与带有邻位锂化方向的基团的芳基溴化物或芳烃的杂耦合。将Pd催化剂与t-BuLi结合使用,可在一锅法中快速有效地形成多种聚芳族化合物,而无需单独制备有机金属偶联剂。这些多芳族结构可在室温下10分钟内以高收率获得,产生的废物最少(E因子低至1.5),并且不需要严格的惰性条件,因此与传统方法相比,该方法非常高效和实用。作为说明,可以轻松地制备广泛使用的BINOL衍生结构的几个关键中间体。
