Paragraph 0279; 0292-0297, (2019/08/30)
PURPOSE: A heterocyclic compound and an organic electroluminescent device containing the same are provided to show stability compared with an existing material and to have superior light emitting properties such as low driving voltage or current efficiency. CONSTITUTION: A heterocyclic compound is denoted by chemical formula 1. An organic electroluminescent device comprises an anode, a cathode, and layers containing the heterocyclic compounds, which is placed between the anode and the cathode. A light emitting layer between the anode and the cathode contains the heterocyclic compounds. The organic electroluminescent device further comprises one or more layers selected among a hole injection layer, a hole transport layer, an electron blocking layer, a hole blocking layer, an electron transport layer, and an electron injection layer.

A facile approach to the synthesis of 5,7-disubstituted indoles via a highly selective lithium-bromine exchange of 5,7-dibromoindoles

A general approach to the synthesis of 5,7-disubstituted indoles has been developed based upon a highly selective lithium-bromine exchange reaction at the 7-position when 1-alkyl-5,7-dibromoindoles were treated with t-BuLi in ether. The resulting 5-bromo-7-lithiated indoles could react with various electrophiles to afford 5-bromo-7-substituted indoles (6) upon work-up. Without isolation of 6, the intermediates thus obtained could be exposed to a second lithium-bromine exchange reaction in a one-pot procedure and further reacted with various electrophiles to afford 5,7-disubstituted indoles (1).
