Influence of Ligand Design and Non‐Covalent Interactions on the Isoselective Ring‐Opening Polymerization of rac‐ß‐Butyrolactone using Salan and Salalen Rare‐Earth Metal Catalysts

open access: yesAngewandte Chemie International Edition, Accepted Article.
We herein report the influence of the ligand framework on the isoselective ring‐opening polymerization (ROP) of rac‐β‐butyrolactone using highly active in situ generated salan [ONNO]H2 and salalen [ONNO]H rare‐earth metal complexes. The stereochemistry was found to be highly dependent on the ortho‐substituents, enabling the synthesis of either ...
