本研究的目的是利用簡單的合成方法,在較低溫及液相的條件下,製備碗狀化合物及其衍生物,取代真空熱裂解法(FVP)。以往的合成方法,因為有低官能基容忍度、前驅物不易製備、反應溫度過高和不易純化等缺點,故我們希望以過渡金屬催化的方式,來進行碗狀化合物的合成。我們透過合成出的有機平面中間物,以過渡金屬催化,進行碳-碳鍵耦合,而得到所要的碗狀化合物。另一方面,我們也將導入異丙基為碗狀化合物上的取代基,來測量其分子間的反轉能障。由氫核磁共振光譜測得的結果,我們觀察到在零下八十度時其訊號峰圖形和其他較高溫度時的圖形有所差異。
鈀金屬催化劑、鹼、溶劑及反應溫度於此反應中均扮演關鍵的角色。透過一系列的測試實驗,我們已找出反應最佳化的條件:將9-(2,6-二氯苯)-10-(2-氯苯)菲、二氯雙(三環己基磷)鈀(II)、1,8-二氮雜環十一烯和碳酸銫,溶於N-甲基吡咯酮,在150 ºC下,經過約48小時,可得到21%產率的二茚基[1,2,3,4-defg:1',2',3',4'-mnop]筷,利用相同的操作步驟,亦可得到異丙基取代的碗狀化合物。
The goal of this research is to develop a simple synthetic method for the preparation of bowl-shaped compounds and their derivatives at lower temperature and in solution phase to replace the method of flash vacuum pyrolysis (FVP). In the past synthetic methods existed some drawbacks, including low functional group tolerance, inconvenient precursor preparation, high reaction temperature and difficulty of purification, here we hope to use transition metals to synthesize bowl-shaped compounds. We employed the transition metal, Pd, an activator of the organic plane intermediate to proceed carbon-carbon bond coupling reaction. Meanwhile, we introduced an isopropyl substitution group to the bowl-shaped compound, and measured its bowl-to-bowl inversion barrier. The result of the 1H NMR spectrum, we found, the peak have difference signal at 80 oC with other temperature.
Systematic studies of the reaction conditions revealed that palladium catalyst, base, solvent and temperature all play key roles. The reaction conditions have been optimized. Upon heating 9-(2,6-dichlorophenyl)-10 -(2-chlorophenyl)phenanthrene in NMP at 150 ºC for 48 hours with a mixture of PdCl2(PCy3)2, DBU and Cs2CO3 can obtain diindeno[1,2,3,4- defg:1',2',3',4'-mnop]chrysene in 21% yield. Utilizing the same operation step can also give the isopropyl-substituted compound.
