Abstract
Official abstract text for this publication.
This invention relates generally to metathesis catalysts and the use of such catalysts in the metathesis of olefins and olefin compounds, more particularly, in the use of such catalysts in Z and E selective olefin metathesis reactions. The invention has utility in the fields of organometallics and organic synthesis.
First claim
Opening claim text (preview).
What is claimed is: 1. A compound selected from: 2. The compound as claimed in claim 1 , wherein the compound is C745, C817 or C849z. 3. The compound as claimed in claim 1 , wherein the compound is C925, C746 or C782. 4. The compound as claimed in claim 1 , wherein the compound is C766, C842 or C753. 5. The compound as claimed in claim 1 , wherein the compound is C727, C777 or C789. 6. The compound as claimed in claim 1 , wherein the compound is C789, C763 or C813. 7. The compound as claimed in claim 1 , wherein the compound is C825, C799 or C849f. 8. The compound as claimed in claim 1 , wherein the compound is C857, C831c or C881. 9. The compound as claimed in claim 1 , wherein the compound is C789a, C761 or C858. 10. The compound as claimed in claim 1 , wherein the compound is C849z. 11. A method for performing a cross metathesis reaction, comprising: contacting a first olefin reactant with a second olefin reactant in the presence of a compound according to claim 1 , under conditions effective to promote the formation of at least one cross metathesis product. 12. The method according to claim 11 , wherein the first olefin reactant and the second olefin reactant are the same. 13. The method according to claim 11 wherein the first olefin reactant and the second olefin reactant are different. 14. The method according to claim 11 , wherein the first olefin reactant and the second olefin reactant are each in a Z-configuration. 15. The method according to claim 14 , wherein the at least one cross metathesis product is greater than 80% Z. 16. The method according to claim 11 , wherein the first olefin reactant and the second olefin reactant are each in an E-configuration. 17. The method according to claim 16 , wherein the at least one cross metathesis product is greater than 80% E.
