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.
