  • Catalyst for ring expansion metathesis polymerization of cyclic monomers
    Patent number: 11794178
    Abstract: A tetraanionic OCO pincer ligand metal-oxo-alkylidene complex is prepared from a trianionic pincer ligand supported metal-alkylidyne. The metal can be tungsten or other group 5-7 transition metal. The tetraanionic pincer ligand metal-oxo-alkylidene complex, a trianionic OCO pincer ligand metal complex, or a trianionic ONO pincer ligand metal complex can be used to polymerize cycloalkenes. The poly(cycloalkene)s are predominantly cis-alkene macrocyclics.
    Type: Grant
    Filed: January 18, 2022
    Date of Patent: October 24, 2023
    Assignee: University of Florida Research Foundation, Inc.
    Inventors: Adam S. Veige, Stella Almeida Gonsales
