Palladium-catalyzed double N-arylation to synthesize multisubstituted dibenzoazepine derivatives
摘要:
Palladium-catalyzed double N-arylation of primary amines with (Z)-1,2-bis(2-bromophenyl)ethenes was investigated. A variety of dibenzoazepine derivatives were synthesized in good to excellent yields. (C) 2012 Elsevier Ltd. All rights reserved.

The present invention relates to novel organic electroluminescent compounds, and organic electroluminescent devices employing the same as electroluminescent material. Specifically, the organic electroluminescent compounds according to the invention are characterized in that they are represented by Chemical Formula (1):
wherein, A and B independently represent CR
7
or N, provided that both A and B cannot be CR
7
or N at the same time; and X is O or S.
Since the organic electroluminescent compounds according to the invention have good luminous efficiency and excellent color purity and life property of material, OLED's having very good operation life can be manufactured therefrom.
