电子在立方体中:作为电子受体的 perfluorocubane 的合成和特征

Bromination and chlorination of aromatic rings by electrophilic aromatic substitution reactions are easily achieved, but fluorination and iodination are difficult to achieve. Fluorine is so reactive that its reaction with benzene is difficult to control, resulting in poor yields of monofluoroaromatic products. To address this, Selectfluor reagent is used as a fluorine source in which a fluorine atom is bonded to a positively charged nitrogen.

The electron affinity (EA) is the energy change for adding an electron to a gaseous atom to form an anion (negative ion).
