P,O-Phosphinophenolate zinc(ii) species: synthesis, structure and use in the ring-opening polymerization (ROP) of lactide, ε-caprolactone and trimethylene carbonate

Structurally diverse phosphinophenolate Zn(ii) heteroleptic and homoleptic compounds are reported, some of which efficiently mediate the controlled ROP of lactide, ε-caprolactone and trimethylene carbonate under living and immortal conditions.
