Patent ID: 8063232

Claim:
A metathesis catalyst compound represented by the formula: where: M is a Group 8 metal; X and X 1 are, independently, any anionic ligand, or X and X 1 may be joined to form a dianionic group and may form single ring of up to 30 non-hydrogen atoms or a multinuclear ring system of up to 30 non-hydrogen atoms; L is N, O P, or S; R is hydrogen or a C 1 to C 30 hydrocarbyl or substituted hydrocarbyl; R 1 , R 2 , R 3 , R 4 , R 5 , R 6 , R 7 , and R 8 are, independently, hydrogen or a C 1 to C 30 hydrocarbyl or substituted hydrocarbyl; each R 9 and R 13 are, independently, hydrogen, a C 1 to C 30 hydrocarbyl or substituted hydrocarbyl; R 10 , R 11 , R 12 are, independently, hydrogen or a C 1 to C 30 hydrocarbyl or substituted hydrocarbyl; each G, is, independently, hydrogen, halogen or C 1 to C 30 substituted or unsubstituted hydrocarbyl; and where any two adjacent R groups may form a single ring of up to 8 non-hydrogen atoms or a multinuclear ring system of up to 30 non-hydrogen atoms.
