Stereoselective polymerization of <i>rac</i>-lactide catalyzed by zwitterionic calcium complexes
نویسندگان
چکیده
Two zwitterionic calcium complexes L1CaN(SiMe3)2(THF) (1) and L2CaN(SiMe3)2 (2) via protolysis reaction were synthesized. At ?75 °C, 1 gave a heterotactic sequence enriched polylactide, whilst 2 produced an isotactic polymer.

New sterically encumbered N-heterocyclic carbene catalysts were synthesized and used to polymerize rac-lactide to give highly isotactic polylactide or meso-lactide to give heterotactic polylactide.
متن کاملChiral indium alkoxide complexes as initiators for the stereoselective ring-opening polymerization of rac-lactide.
The indium complex InL(2)N'' has been prepared from the reaction of 2 equiv of ((t)Bu)(2)P(O)CH(2)CH((t)Bu)OH (HL) with InN''(3) (N'' = N(SiMe(3))(2)). This complex reacts with a further equivalent of 2,6-di-tert-butylphenol or HL to afford the adducts InL(2)(OAr) and InL(3), respectively. Confirmation that the anion L(-) exhibits "ligand self-recognition" in the formation of predominantly homo...
متن کاملEnolic schiff base aluminum complexes and their catalytic stereoselective polymerization of racemic lactide.
A series of enolic Schiff base aluminum(III) complexes LAlR (where L=NNOO-tetradentate enolic Schiff base ligand) containing ligands that differ in their steric and electronic properties were synthesized. Their single crystals showed that these complexes are five-coordinated around the aluminum center. Their coordination geometries are between square pyramidal and trigonal bipyramidal. Their ca...
