A series of zinc and magnesium complexes containing pyrazolyl- phenolate ligands have been synthesized. Complexes 44-49 were characterized by NMR spectroscopy and elemental analysis. The molecular structures of complexes 44, 47 and 48 were determined by single-crystal X-ray diffraction techniques. Complexes 44-47 show efficient activity in the ring-opening polymerization of L-lactide and ε-caprolactone in the presence of benzyl alcohol, yielding polymers with controlled molecular weight and narrow molecular weight distribution. They also exhibit both “living” and “immortal” characters.
