Palladium-Catalyzed Direct Intermolecular Amination of Unactivated Methylene C(sp<sup>3</sup>)–H Bonds with Azodiformates via Bidentate-Chelation Assistance
An efficient and convenient method enabling direct amination of unactivated methylene C(sp3)–Hbonds to form C–N bonds with azodiformates as amino source is described. This method highlights the emerging strategy of unactivated methylene as versatile functional groups in organic synthesis and provides a strategy to construct functionalized C–N bonds for the synthesis of complex molecules.
