resumo
The synthesis of diarylamines has attracted a great deal of interest due to their
importance in diverse fields as natural biological active products and analogues,
photography and materials science.
Herein we report the synthesis of diarylamines 1 bearing electron donating or
withdrawing groups by palladium catalyzed amination, in good yields (50%-quantitative
yield) using two different bases and choosing the right components.
