- Abstract
- Cobalt(II) and copper(II) complexes supported by 4-(quinolin-2-ylmethyl)morpholine (L) were characterized, and their reactivity toward the ring-opening polymerization (ROP) of rac-lactide (rac-LA) was studied. The use of [LMCl2]/(LiOPr)-Pr-i and [LMCl2]/LiMe (M = Co, Cu) resulted in over 95% conversion within 10 min at 25 degrees C. The effect of the initiating group and geometry of the metal complexes steered the heterotactic enchainment of the resultant polylactide(PLA). The Co(II)/LiMe system represents the first example of the ROP of rac-LA with high heterotactic enchainment (P-r = 0.92) with 98% conversion at 0 degrees C.
