Generation of diarylnitrenium ions from N-(N,N-diarylamino)phthalimides by treatment with AlCl(3) in benzene or in 1,2-dichloroethane leads to formation of carbazoles by intramolecular C-C bond formation. The reaction proceeds in synthetically useful yields.
通过在苯或1,2 - 二氯乙烷中用氯化铝处理N - （N，N - 二芳基氨基）邻苯二甲酰亚胺来生成二芳基氮鎓离子，会通过分子内C - C键的形成导致咔唑的形成。该反应以具有合成实用性的产率进行。
