Redox-controlled polymerization of lactide catalyzed by bis(imino)pyridine iron bis(alkoxide) complexes.
TL;DR: The reaction displayed characteristics of a living polymerization with production of polymers that exhibited low molecular weight distributions, linear relationships between molecular weight and conversion, and polymer growth observed for up to fifteen sequential additions of lactide monomer to the polymerization reaction.

Block Copolymerization of Lactide and an Epoxide Facilitated by a Redox Switchable Iron‐Based Catalyst
TL;DR: A cationic iron(III) complex was active for the polymerization of various epoxides, whereas the analogous neutral iron(II) complex is inactive as discussed by the authors, which is orthogonal to what was observed previously for lactide polymerization.

TL;DR: Electrical and computational investigation into the electronic structures of iron-based ring opening polymerization catalysts revealed that they are most accurately described as containing a high spin iron(ii) center that is antiferromagnetically coupled to a singly reduced bis(imino)pyridine ligand, which results in superior catalytic performance for the more highly reduced 3a and 3b compared to the increasingly more oxidized complexes.

TL;DR: In this paper, a unique redox-triggered crosslinking reaction is disclosed that capitalizes on the orthogonal reactivity of an iron-based catalyst for the ring opening polymerization of cyclic diesters and epoxides.
