  • Succinic anhydrides from epoxides
    Patent number: 9376413
    Abstract: Catalysts and methods for the double carbonylation of epoxides are disclosed. Each epoxide molecule reacts with two molecules of carbon monoxide to produce a succinic anhydride. The reaction is facilitated by catalysts combining a Lewis acidic species with a transition metal carbonyl complex. The double carbonylation is achieved in single process by using reaction conditions under which both carbonylation reactions occur without the necessity of isolating or purifying the product of the first carbonylation.
    Type: Grant
    Filed: November 25, 2014
    Date of Patent: June 28, 2016
    Assignee: Cornell University
    Inventors: Geoffrey W. Coates, John M. Rowley
