Indium-catalyzed annulation of 3-aryl- and 3-heteroarylindoles with propargyl ethers: synthesis and photoluminescent properties of aryl- and heteroaryl[c]carbazoles

摘要

Treatment of 3-aryl- and 3-heteroarylindoles with propargyl ethers under indium catalysis successfully provided aryl-and hetero-aryl[c]carbazoles, which were found to be more efficient emitters compared with the corresponding [a]-analogs.
