摘要

Diazabutadienes (DABs) were chosen as ancillary ligands in the Cu-catalyzed C–N coupling reaction for the synthesis of triarylamines. A combination of CuI/DAB (1)[1: N, N′- bis (2, 6-diisopropylphenyl)-1, 4-diaza-1, 3-butadiene] was found to be an efficient catalyst system for N-arylation of diarylamines and anilines with aryl iodides, affording the desired products in good to excellent yields.
