Abstract:
This invention relates to a metathesis catalyst comprising (i) a Group 8 metal hydride-dihydrogen complex represented by the formula: wherein M is a Group 8 metal; X is an anionic ligand; and L1 and L2 are neutral donor ligands; and (ii) a ligand exchange agent represented by the formula J-Y, wherein J is selected from the group consisting of hydrogen, a C1 to C30 hydrocarbyl, and a C1 to C30 substituted hydrocarbyl; and Y is selected from the group consisting of halides, alkoxides, aryloxides, and alkyl sulfonates.
