Cerium(III) and neodymium(III) amides derived from a chelating 2-pyridyl amido ligand.
Homoleptic Ce(III) and Nd(III) triamides [LnL(3)] [Ln = Ce(1) or Nd(2)] and the heterobimetallic amide-alkoxide derivatives [LnL(2)(mu-OBu(t))2M(tmeda)] [Ln = Ce, M = Na (3); Ln = Nd, M = Na (4); Ln = Nd, M = K (5)] supported by the bulky [N(SiBu(t)Me2)(2-C(5)H(3)N-6-Me)]- ligand (L-) have been successfully synthesized and characterized. Complexes 1-3 and 5 show a high activity toward the ring-opening polymerization of epsilon-caprolactone.
