摘要:
There is disclosed a process for the production of N-substituted carbazoles with high efficiency, in which a carbazole compound is reacted with an appropriate halogenated compound in an inert solvent in the presence of an acid-removing agent and an amine without using any quaternary ammonium salt which is required in the conventional process.
