The addition of functionalized arylmagnesium halides to nitroarenes in THF (-20 degrees C, 2 h) provides, after reductive workup (FeCl(2), NaBH(4)), various polyfunctional diarylamines in 63-86% yield. Heterocyclic arylated amines can be prepared by this one-pot procedure. A mechanistic rationale of this reaction is given.

A terphenyl phosphine ligand (2,6-bis(2,4,6-triisopropylphenyl)phenyl-dicyclohexylphosphine, TXPhos) and its supported palladium complex [(TXPhos)(allyl)PdCl] have been developed and the catalyst system is highly efficient in amination of arylhalides with 1° anilines, especially effective for densely functionalized substrates including both partners possessing ortho-ester, acetyl, nitrile and nitro
