New publication featured as ACS Editors' Choice

4 August 2026

A publication from the Williams Group at the University of Oxford has been selected to be featured as an ACS Editors' Choice.

The new article titled "Understanding Catalytic Synergy in Heterodinuclear Iron/s-Block Complexes for Epoxide/Anhydride Ring-Opening Copolymerization" published in ACS Catalysis has been selected to be featured as an ACS Editors' Choice.

To be chosen as an ACS Editors' Choice is an honour awarded to just one paper each day from across the ACS Publications portfolio of more than 90 peer-reviewed journals. This represents fewer than 1% of the more than 50,000 articles published annually.

"We use microscale calorimetry to investigate the performance of earth-abundant iron/s-block metal catalysts for the production of polyesters. The results provide insight into the origins of synergic rate enhancements in heterodinuclear catalysts, and guide the development of more efficient iron polymerization catalysts." - PhD Researcher, Frederica Butler

🗨️ "We report on mixed metal iron/s-block metal catalysts for the copolymerization of epoxides and anhydrides, to make semi-aromatic polyesters. We investigate the metal combinations using calorimetry to elucidate kinetics and transition state barriers. The most effective catalyst features Fe(III)/K(I) — it is both fast and selective" - Prof Charlotte Williams
