Enantiomeric Binaphtyl-brided SALEN Zirconium Complexes as Catalysts for Stereoselective Polymerization of Chiral Olefins

摘要

1 Results Chiral Schiff-base complexes have been used as catalysts for several stereoselective organic transformations,but they have never been tested for the polymerization of chiral olefins.The preferential polymerization of a single monomeric enantiomer (stereoselective polymerization) pursues two intriguing goals: i) the development of polymeric materials with peculiar optical or physical properties and ii) the kinetic resolution of racemic alkenes.
