Regioselective Radical Arylation of Aromatic Diamines with Arylhydrazines
aerospace materials, for example, Kapton®. The arylation of aromatic diamines with arylhydrazine hydrochlorides was achieved in reasonable yields. This new and simple reaction occurred at room temperature in air using an inexpensive base. This transformation seems to proceed via a homolyticaromaticsubstitution (HAS) mechanism. The synthesized aromatic diamines are used as raw materials for polyimides, including
