4-defg;1',2',3',4'-mnop]chrysenes 2 were straightforwardly prepared in around 20% yield from 9,10-diarylphenanthrenes 3 by palladium-catalyzed intramolecular arylations. The bowl-to-bowl inversion barrier for buckybowl 2-iPr is predicted to be approximately 7 kcal mol(-1) based on density functional theory calculations and this value is consistent with the results of a variable-temperature (1)H-NMR
二钯[1,2,3,4-defg; 1',2',3',4'-mnop] chrysenes 2是由钯催化的分子内芳基化反应从9,10-二芳基菲3直接以约20%的收率制备的。根据密度泛函理论计算,buckybowl 2-iPr的碗对碗反型势垒预计约为7 kcal mol(-1),该值与可变温度(1)H-NMR的结果一致学习。
