Abstract: Abstract This contribution illustrates the significant influence of the Al-catalyzed e-caprolactone (e-CL) and δ-valerolactone (δ-VL) ring-opening polymerizations. A series of β-pyridyl-enamino aluminum complexes [AlLMe2] 1–6 {L = [(2-C5H4N)-C(H) C(Ph) N(Ar) ], Ar = C6H5 (1), 2,6-Me2C6H3 (2), 2,6-Et2C6H3 (3),… read more here.
