CATALYTIC COMPLEXES WITH CARBENE LIGAND, METHOD OF THEIR PRODUCTION AND APPLICATION IN METATHESIS REACTION Russian patent published in 2018 - IPC C07F15/00 C07F19/00 B01J31/24 B01J31/22 

FIELD: chemistry.

SUBSTANCE: invention relates to a catalyst with a carbene ligand characterized by the general structure of the formula (I). In the formula (I), M is a transition metal of group 8; X¹ and X² are identical or different and are two ligands, preferably anionic ligands; R¹-R⁶ are identical or different and are selected from hydrogen, C₁-C₄alkyl, cyclohexyl, C₁-C₄alkoxy, methylphenyl, dimethylphenyl, methoxyphenyl, fluorophenyl, naphthyl, with the exception that R² is not phenyl; where, as an alternative R⁶ is not optionally connected by a bridge to L²; L¹ and L² are identical or different ligands, preferably neutral electron donors. A version of the catalyst, a method of the production of catalysts and their application are also provided.

EFFECT: proposed catalysts can be used in various methods of the metathesis of olefins.
