Beschreibungen/Notizen

• Efficient alkylations of amines by alcohols catalyzed by well-defined Co­(II) complexes are described that are stabilized by a PCP ligand (N,N′-bis­(diisopropylphosphino)-N,N′-dimethyl-1,3-diaminobenzene) based on the 1,3-diaminobenzene scaffold. This reaction is an environmentally benign process implementing inexpensive, earth-abundant nonprecious metal catalysts and is based on the acceptorless alcohol dehydrogenation concept. A range of primary alcohols and aromatic amines were efficiently converted into mono-N-alkylated amines in good to excellent isolated yields.
