Stereoselective and controlled polymerization of D,L-lactide using indium(III) trichloride.
نویسندگان
چکیده
Indium trichloride, benzyl alcohol, and triethylamine (without an added 'directing' multidentate ligand) generate a catalyst in situ for the room temperature polymerization of D,L-lactide affording highly heterotactic polylactide of controlled molecular weight and narrow molecular weight distribution.

The effect of steric changes on the isoselectivity of dinuclear indium catalysts for lactide polymerization.
A series of (±)- and (R,R)-tridentate diamino, ortho/para disubstituted phenolate proligands H(NNO(R)) with various phenolate substituents was synthesized and used to prepare indium dichloride complexes (NNO(R))InCl2via salt metathesis of the deprotonated ligands with indium trichloride. These complexes are dinuclear in the solid state, in contrast to previously reported complexes with t-butyl ...

Group 4 metal initiators with a tetradentate bis(phenolato) ligand polymerized meso-lactide efficiently under ring-opening to give syndiotactic polylactide. L-Lactide was converted faster than rac-lactide and meso-lactide.
متن کاملHighly active and stereoselective zirconium and hafnium alkoxide initiators for solvent-free ring-opening polymerization of rac-lactide.
Under solvent-free conditions (at 130 degrees C), zirconium and hafnium amine tris(phenolate) alkoxides are extremely active, well-controlled, single-site initiators for the ring-opening polymerization of rac-lactide, yielding highly heterotactic polylactide.
متن کاملA highly active and site selective indium catalyst for lactide polymerization.
Chiral indium salen complexes are highly active, isoselective catalysts for the ring opening polymerization of racemic lactide. The polymerizations are well controlled and polymers with high molecular weights and low molecular weight distributions are obtained. Preliminary kinetic investigations with the enantiopure complex confirm enantiomorphic site control as the dominant contributor to sele...
متن کاملGroup 4 initiators for the stereoselective ROP of rac-β-butyrolactone and its copolymerization with rac-lactide.
In this paper we demonstrate the utility of Group 4 metals for the well-controlled and stereoselective (syndiotactic) ring opening polymerization (ROP) of rac-β-butyrolactone (BBL) and their ability to form copolymers.
