  • Catalyst complexes with carbene ligand and method for making same and use in metathesis reaction
    Patent number: 10159966
    Abstract: This invention relates to catalyst compounds and the synthesis and applications useful in olefin metathesis reactions. The catalyst compounds of the invention are represented by the formula (I): wherein M is a Group 8 metal; X1 and X2 are anionic ligands; L1 and L2 are neutral two electron donor ligands. The present invention also relates to an easy applicable catalyst synthesis and the application in different olefin metathesis processes, e.g. Reaction Injection Molding (RIM), process to make ?-olefins from fatty acid ester, e.g. methyl oleate.
