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 C 3 symmetry of the ligand may play an important role in controlling stereoselective chain propagation from the racemic monomer.
