Generation of diarylnitrenium ions from N-(N,N-diarylamino)phthalimides by treatment with AlCl3 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.
<i>N</i>-Phenylation of<i>N</i>-Arylaminophthalimides with Triphenylbismuth and Cupric Acetate: A Convenient Synthesis of 1-Aryl-1- Phenylhydrazines
Abstract Synthesis of 1-aryl-1-phenylhydrazines (2) from N-aryl-N-phenylaminophthalimides (1) which were synthesized by the phenylation of 1 with triphenylbismuth and cupric acetate is described.
