自由基阳离子1中存在稳定的7 π电子系统，其可以以高产率以1-Cl形式获得，例如，通过p-C 6 H 4 Se 2 Cl 2和灰色硒的反应。1-SO 3 CF 3可通过阴离子交换获得，并且在固态下含有包含彼此叠加的1的环的二聚体。由于阳离子-阴离子相互作用，阳离子的库仑排斥减少。
A stable 7 π‐electron system is present in the radical cation 1 which can be obtained in high yields as 1‐Cl, for example, from the reaction of p‐C 6 H 4 Se 2 Cl 2 and gray selenium. 1‐SO 3 CF 3 is accessible by anionic exchange and in the solid state contains dimers comprising rings of 1 superimposed on one another. As a result of cation‐anion interactions, the Coulombic repulsion of the cations is reduced.
