介绍了以双-铃木-宫浦交叉偶联反应为关键步骤合成各种9,10-二芳基并[9,10]-二芳基并[9,10]-二芳基[9,10]-[9,10]-二芳基[9,10]-[9,10]-二芳基[9,10]-[9,10]-二芳基[9,10]-二芳基[9,10]-[9,10]-二芳基[9,10-二芳基][2,5]-[2,4]-2,4,4,4,4,4,4,4,4,4,4,4,4,4,4,4,4,4,4,4,4,4,4,4,4,4,4,4,4,4,4,4,在分子(例如11、12、14)中存在噻吩基的9,10-二硫代菲并[9,10-二亚硫基]并[9,10]-[9,10-二亚硫基]并[9]-[9]-[2]-[2]]的衍生物的可用性可以提供一种容易获得新型聚合物和/或树枝状大分子制备的途径。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合成的不对称9,10-二芳基并菲衍生物20-25。
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.
