Synthesis of various 9,10-diarylanthracene derivatives via bis-Suzuki-Miyaura cross-coupling reaction as a key step is described. Availability of the 9,10-dithienylanthracenes derivatives where the thiophene unit is present in the molecule (e. g. 11, 12, 14) may provide an easy access to novel polymer and/or dendrimer preparation. In addition, we have synthesized unsymmetrical 9,10-diarylanthracene derivatives 20-25 by the Suzuki-Miyaura cross-coupling reaction, which are difficult to prepare by other transition metal-catalyzed cross-coupling reactions.
描述了通过双-Suzuki-Miyaura交叉偶联反应作为关键步骤合成各种9,10-二芳基蒽衍生物。分子中存在噻吩单元的9,10-二噻吩基蒽衍生物(例如11、12、14)的可用性可以提供一种容易获得新型聚合物和/或树枝状聚合物的制备方法。此外,我们还通过Suzuki-Miyaura交叉偶联反应合成了其他过渡金属催化交叉偶联反应难以制备的不对称9,10-二芳基蒽衍生物20-25。
