Chemoselective amination of bromoiodobenzenes with diarylamines by palladium/Xantphos or ligand-free copper catalysts
摘要:
We report the chemoselective amination of bromoiodobenzenes with diarylamines by palladium/Xantphos or a ligand-free copper catalyst. The reactions by these two types of catalysts proceeded with a high chemoselectivity and afforded monobrominated triarylamines in good yields. These products are useful intermediates for the synthesis of unsymmetrical bistriarylamines. (C) 2015 Elsevier Ltd. All rights reserved.
The present invention relates to triaylamines which are substituted by defined groups. These compounds can be used for producing organic electroluminescent devices.
