Bromination of 1,6-diazaphenalene 1 yields a mixture of mono-, di-, and tri-bromo derivatives, while bromination of the conjugate acid 2 provides the 7-bromo isomer 7 in 81% yield. Charge densities and localization energies have been calculated, and are found to be in agreement with the orientation pattern observed during electrophilic substitution. These observations have been employed to develop
1,6-二氮杂菲那烯 1 的溴化产生单、二和三溴衍生物的混合物,而共轭酸 2 的溴化产生 7-溴异构体 7,产率为 81%。计算了电荷密度和局域能,发现它们与亲电取代过程中观察到的取向模式一致。这些观察结果已被用于开发 7-取代的 1,6-二氮杂苯的几种途径。
