Abstract

Novel dichloro zinc complexes based on enantiopure N,N-diamine ligands bearing furanylmethyl and thiophenylmethyl pendent groups were synthesised, and their crystal structures were determined using X-ray crystallography. The isopropoxide derivatives (generated in situ) of these well-characterised complexes efficiently catalysed the ring-opening polymerisation (ROP) of rac-lactide (rac-LA) at two different temperatures under controlled conditions. Highly heterotactic polylactide (PLA) was obtained with P_r = 0.80 at -25 °C in THF.
