A simple technique for the preparation of anions of polycyclic aromatic hydrocarbons is described. 1H and 13C NMR spectra of dianions of pyrene and derivatives of pyrene are reported and discussed. The electron density is greatest at the carbon atoms in the perimeter of the dianions. The presence of an electron-donating substituent at position 2 causes an increase in the charge at positions 1 and 3
描述了一种制备多环芳烃阴离子的简单技术。报告并讨论了的二价阴离子和derivatives的衍生物的1 H和13 C NMR谱。电子密度在二价阴离子周围的碳原子处最大。在位置2上存在供电子性取代基,导致位置1和3上电荷增加。
