| abstract |
This invention relates to a catalyst compound for the metathesis of olefins represented by the formula: n n n n n n n n n n n n wherein M is a Group 8 metal; X and X 1 are anionic ligands; L is a neutral two electron donor; L 1 is N, O, P, or S, preferably N or O; R is a C 1 to C 30 hydrocarbyl or a C 1 to C 30 substituted hydrocarbyl; G* is selected from the group consisting of hydrogen, a C 1 to C 30 hydrocarbyl, and a C 1 to C 30 substituted hydrocarbyl; R 1 is selected from the group consisting of hydrogen, a C 1 to C 30 hydrocarbyl, and a C 1 to C 30 substituted hydrocarbyl; and G is independently selected from the group consisting of hydrogen, halogen, C 1 to C 30 hydrocarbyls and C 1 to C 30 substituted hydrocarbyls. n n n n n This invention also relates to process to make alphaolefins comprising contacting an olefin, such as ethylene, with a feed oil containing a triacylglyceride (typically a fatty acid ester (such as methyl oleate)) with the catalyst compound described above. The fatty acid ester may be a fatty acid methyl ester derived from biodiesel. |
