The materials based on aliphatic polyesters attract great attention due to their biodegradation and biocompatibility. The ring opening polymerization (ROP) initiated by metal complexes is the most used method for the synthesis of such materials due to reproducibility and reaction control. The search for new active initiators for ROP is the actual problem for modern organometallic and polymer chemistry. In this work we have obtained novel aluminum complexes on the basis of known or new ligands. The structures of the complexes obtained were investigated by multinuclear NMR spectroscopy and in several cases by X-ray analysis. The complexes obtained exhibit catalytic activity in the polymerization of ε-caprolactone and D,L-lactide.
