Ge whiz: Highly stereoselective bulk ring-opening polymerization of rac-lactide to afford a heterotactic polymer was achieved for the first time through the use of a single-site germanium alkoxide initiator. The C3 symmetry of the ligand may play an important role in controlling stereoselective chain propagation from the racemic monomer.
