Aminophosphonium organocatalysts for the ring-opening copolymerisation of epoxide and cyclic anhydride

Chem. Commun., 2024, Advance Article DOI: 10.1039/D4CC03947E, Communication Ella F. Clark, Estelle Dunstan, Gabriele Kociok-Köhn, Antoine Buchard The Kirsanov reaction has been used to synthesise air stable, efficient and selective bifunctional aminophosphonium catalysts for the alternating ring-opening copolymerisation (ROCOP) of CHO/PA without the need for a co-initiator.
