Hybrid amino/iminopyridines with auxiliary phosphines enabling active zinc catalysts for the ring-opening polymerization of lactide
Abstract
. The observed activities with respect to substituents were isopropyl > ethyl > methyl; thus, higher activities were achieved for more alkyl substituents. The auxiliary phosphine enhanced the activities of the zinc complexes; Zn1-Zn5 showed higher activities than Zn6 (with butyl), which formed the PLA with a lower molecular weight. The coordination-insertion and ring-expansion mechanisms have been proposed for the ROP of L-lactide.
