The present invention provides novel anthracene derivatives. In particular, the present invention provides light-emitting elements with high luminous efficiency, and light-emitting elements with long lifetime. Further, the present invention provides light-emitting devices and electronic devices having long lifetime by using these light-emitting elements. An anthracene derivative represented by the general formula (1) is provided. In addition, since the anthracene derivative represented by the general formula (1) has high luminous efficiency, a light-emitting element using the anthracene derivative represented by the general formula (1) can also have high luminous efficiency. By using the anthracene derivative represented by the general formula (1), light-emitting elements with long lifetime can be provided.
‐1,1’‐biaryls. Various 9‐(arylamino)aryl‐9H‐carbazoles could be synthesized from aryl(haloaryl)amines and 9H‐carbazole derivatives in high yields by the use of tBu‐XPhos. The amination of 4‐bromotoluene with a mixture of diphenylamine and 9H‐carbazole gave only 9‐o‐tolyl‐9H‐carbazole with tBu‐XPhos, while the use of PtBu3 or XPhos afforded the mixture of 9‐o‐tolyl‐9H‐carbazole and diphenyl(o‐tolyl)amine
研究了钯与9 H-咔唑衍生物的芳基(卤代芳基)胺的胺化反应。在使用Pd 2(dba)3 / P t Bu 3 / NaO t Bu催化剂与9 H-咔唑胺化(4-溴苯基)苯胺中,主要产物为9- [4-(苯基氨基)苯基] -9 H-咔唑,收率60%,其中(4-溴苯基)苯胺转化率> 99%,并伴随形成9- [4- [苯基[4- [苯基[4-(苯基氨基)苯基]氨基]苯基] -9 H观察到连续产生的副产物咔唑(产率为15%)。使用XPhos代替P t Bu 3时,以81%的收率提供所需的产品,并将连续的副产品抑制到7.7%。通过使用t Bu‐XPhos ,所需产品的收率达到98%。用其他2-二叔丁基或2-二(1-金刚烷基)膦基-1,1'-联芳基也获得了如此优异的所需产品收率。可以通过使用t Bu-XPhos从芳基(卤代芳基)胺和9 H-咔唑衍生物高产率合成各种9-(芳基氨基)芳基-9 H-咔唑。用二苯胺和9
