在本篇論文中,主要目標在於合成一個新型星狀放射型的triarylamine 24 ( N1,N1,N4,N4-tetra[4-(diphenylamino)phenyl]-
1,4-benzenediamine),我們將分為兩個合成策略,第一個部份,我們設計將化合物24分解為化合物25和26經由偶合反應而得到,而化合物25可利用化合物27和28進行反應而取得,而化合物27和28又分別利用化合物4-硝基苯胺30和碘化苯進行偶合反應得到29再進行還原反應得到27,以及4-碘基苯胺31和碘化苯進行偶合反應得到28。

在第二個合成策略中,我們想利用一個可取得的起始物38,在其四個胺基上進行偶合反應,希望使其每一個胺基上,順利接上兩個苯環。由以上合成策略希望可合成化合物24一個新型的星狀放射型的triarylamine 類的化合物。

The target of this thesis research is to prepare a novel starburst triarylamine 24 (N1,N1,N4,N4-tetra[4-(diphenylamino)phenyl]-1,4-
Benzenediamine). We used two approaches. In this first approach, we planned to couple compounds 25 and 26 to afford 24. But this coupling reaction did not work as expected. Compounds 25 was prepared from 27 and 28. Reduction of compound 29 gave 27. Compound 29 was obtained from reaction of 4-nitroaniline with iodobenzene. Compound 28 was synthesized from 4-iodoaniline and iodobenzene. In the second approach, we prepared compound 38. However, reaction of 38 with iodobenzene using various catalyst could not produce the desired starburst triarylamine 24.
