  • Ruthenium-based complexes, their preparation and use as catalysts
    Patent number: 9920086
    Abstract: The present invention relates to novel Ruthenium-based complex compounds which represent viable catalysts, in particular for all sorts of metathesis reactions. Such complex compounds can be prepared by a novel, very favorable and cost efficient method which includes the introduction of an alkylidene ligand into the complex by using vinyl sulfides or vinyl ethers.
    Type: Grant
    Filed: May 20, 2014
    Date of Patent: March 20, 2018
    Assignees: ARLANXEO DE GMBH, THE GOVERNING COUNCIL OF THE UNIVERSITY OF TORONTO
    Inventors: Douglas Wade Stephan, Clinton Lund, Michael Sgro, Fatme Dahcheh, Christopher Ong
  • Ruthenium-based complex catalysts
    Patent number: 9828401
    Abstract: The present invention provides novel Ruthenium-based transition metal complex catalysts comprising specific ligands, their preparation and their use in hydrogenation processes. Such complex catalysts are inexpensive, thermally robust, and olefin selective.
    Type: Grant
