  • Cyclic alkyl amino carbene (CAAC) ruthenium complexes as improved catalysts for ethenolysis reactions
    Patent number: 9249170
    Abstract: Described herein are compounds and methods of catalyzing ethenolysis reactions, optionally on an industrial scale. In certain embodiments, the catalysts bear cyclic alkyl amino carbene (CAAC) ligands with an ortho substituent, such as a methyl substituent, on an N-aryl ring. When used to catalyze ethenolysis reactions, certain such compounds produce a turnover number greater than 50,000.
    Type: Grant
    Filed: April 10, 2014
    Date of Patent: February 2, 2016
    Assignees: California Institute of Technology, The Regents of the University of California
    Inventors: Vanessa M. Marx, Mohand-Ameziane Melaimi, Scott C. Virgil, Benjamin K. Keitz, Robert H. Grubbs, Guy Bertrand
