Synthesis of diarylamines in the benzo[b]thiophene series bearing electron donating or withdrawing groups. In XXth European Colloqium on Heterocyclic Chemistry. Estocolmohttp://hdl.handle.net/10198/3887The 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.engSynthesis of diarylamines in the benzo[b]thiophene series bearing electron donating or withdrawing groupsconference object
