Abstract
Magnesium and calcium coordination compounds (dpp-bian)Ca(thf)4 (1), (dpp-bian)2Mg (2), and (dpp-bian)2Ca (3), containing a chelating redox-active acenaphthenediimine ligand, dpp-bian {1,2-bis-[(2,6-diisopropyl)phenylimino]acenaphthene}, were studied as L-lactide ring-opening polymerization catalysts. The interaction of complex 1 with L-lactide in solution was studied by ESR spectroscopy. The solvent effect on the polymerization rate and molecular-mass characteristics of the polymers obtained was demonstrated.
