We verified its potential utility as a valuable scaffold for chirality induction through the preparation of enantiopure zinc complexes, which behave as highly efficient initiators to produce highly-enriched isotactic poly(lactide)s (Pi up to 0.88).engAttribution-NonCommercial-NoDerivatives 4.0 Internacionalhttp://creativecommons.org/licenses/by-nc-nd/4.0/QuímicaZincenantiopure ligandisotactic polymerlactidePLASynthesis of an Enantiopure Scorpionate Ligand by a Nucleophilic Addition to a Ketenimine and a Zinc Initiator for the Isoselective ROP of rac-Lactideinfo:eu-repo/semantics/preprint10.1039/C9CC04716Finfo:eu-repo/semantics/openAccess23 Química
