Bis(imino)pyridine alkoxide complexes previously used for the polymerization of lactones are reported for the polymerization of N-carboxyanhydrides (NCAs) and the copolymerization of NCAs. The polymerization of NCAs and lactones to polyamides and poly(ester-amides) respectively. Although many catalysts have only been developed for the polymerization of NCAs and lactones, few have been reported for both monomers. The unique capabilities of the iron complexes used for producing polyamides poly(ester-amides) stems from the unique electronics of the low-valent, iron catalysts. These features along with the generality of the current system will be discussed. Preliminary mechanistic insight into the unusual reactivity of these complexes will also be disclosed.
