摘要

2, 2′-Diamino-1, 1′-biaryls were found to undergo ring-closure condensation reaction to afford benzo [c] carbazoles in good to excellent yield. Coupled with the synthesis of 2, 2′- biaryldiamines from diaryl hydrazides via [3, 3]-sigmatropic rearrangement, it constitutes a new efficient synthetic method for benzo [c] carbazoles and related compounds.
