CATALYST COMPLEXES WITH CARBENE LIGAND AND METHOD FOR MAKING SAME AND USE IN METATHESIS REACTION

摘要

This invention relates to catalyst compounds and the synthesis and applications useful in olefin metathesis reactions. The catalyst compounds of the invention are represented by the formula (I): wherein M is a Group 8 metal; X1 and X2 are anionic ligands; L1 and L2 are neutral two electron donor ligands. The present invention also relates to an easy applicable catalyst synthesis and the application in different olefin metathesis processes, e.g. Reaction Injection Molding (RIM), process to make α-olefins from fatty acid ester, e.g. methyl oleate.

1. Catalyst with carbene ligand having a general structure of formula (I): Wherein M is a Group 8 transition metal; X1 and X2 are identical or different and represent two ligands, preferably anionic ligands; R1-R6 are identical or different and selected from hydrocarbyl, substituted hydrocarbyl, heteroatom containing hydrocarbyl, substituted heteroatom-containing hydrocarbyl, and functional groups, except that R2 does not represent phenyl; wherein alternatively in each case two directly adjacent radicals from the group of R2-R6, including the ring carbon atoms to which they are attached by a cyclic bridging group, generating one or more cyclic structures, including aromatic structures; wherein alternatively R6 is optionally bridged with a different ligand of the metal carbene complex catalyst; L1 and L2 are identical or different ligands, preferably represent neutral electron donors, wherein L2 can be bridged alternatively by a radical R6.
