  • MULTICOORDINATED METAL COMPLEXES FOR USE IN METATHESIS REACTIONS
    Publication number: 20150080581
    Abstract: Improved catalysts useful in alkyne or olefin metathesis are made by bringing into contact a multi-coordinated metal complex comprising a multidentate Schiff base ligand, and one or more other ligands, with a selected activating compound under conditions such that at least partial cleavage of a bond between the metal and the multidentate Schiff base ligand of said metal complex occurs.
    Type: Application
    Filed: November 25, 2014
