A number of 1,8‐bis(1‐naphthyl)‐naphthalenes have been prepared with a combination of electron‐rich and electron poor in the two 1‐naphthyl rings. The conformational analysis by NMR and ECD spectroscopy, aided by DFT calculations, showed that the atropisomers ratio and the conformational preferences within each atropisomer are mainly due to the Coulombic interactions between the two facing rings.
制备了许多1,8-双(1-萘基)-萘,在两个1-萘环中同时结合了富电子和贫电子。通过NMR和ECD光谱进行的构象分析,借助DFT计算表明,每个阻转异构体中的阻转异构体比率和构象偏好主要归因于两个相对环之间的库仑相互作用。
