New paper on phostones and poly(phosphonate)s!

Great work by Emily with the Wurm group at the Max Planck Institute for Polymer Research. This paper describes the synthesis of phostones, i.e., 2-alkoxy-2-oxo-1,3-oxaphospholanes, and their use in the preparation of linear poly(phosphonate)s via ring-opening polymerization resulting in polymers with a hydrolytically stable P–C bond in the polymer backbone. Phostones have the stable P–C bond within the cycle, which leads to a dramatic increase of the monomer stability toward hydrolysis and long shelf-lives compared to other cyclic phosphoesters, which hydrolyze immediately at contact with water.
