The invention concerns the ruthenium complexes of the formula 1: acting as pre(catalysts) in the reaction of metathesis of olefins, as well as a method for their production, and their usage.

Ruthenium complexes, method of their production and their usage

Described herein are novel metal complexes, especially ruthenium complexes, represented by the formula (1): wherein Lis a N-heterocyclic carbene ligand, Lis a neutral phosphine ligand, preferably tricyclohexyl-phosphine, and process of catalyzing olefin metathesis reactions, especially tetra-substituted olefin metathesis reactions.

Metal complexes, especially the ruthenium complexes, and use thereof

Disclosed is a method of producing an organic compound. The method uses a metathesis catalyst in a coupling reaction of an olefin. The method comprises the steps of introducing the olefin into a container; either placing the container under vacuum or bubbling a gas through the olefin; adding an additive with the olefin; mixing the olefin and the additive, the mixing creating a mixture; adding an amount of the metathesis catalyst to the mixture, the amount being less than about 100 ppm by weight of the mixture; and optionally heating the mixture to a temperature, the temperature being greater than room temperature.

Method of producing olefins via metathesis

The present invention provides new ruthenium complexes of Formula (1), which contain a chelate ring created by a halogen atom X. The invention concerns also a method for the preparation of the new ruthenium complexes and their application in metathesis reactions.

Polyhedral oligomeric silsesquioxane (POSS)-linked ligands

The present invention provides ruthenium complexes of the formula wherein: The invention also provides methods for producing the inventive ruthenium complexes and the use of the complexes for carrying out metathesis reactions.

Complexes of ruthenium, method of production thereof and use thereof as (pre)catalysts of the metathesis reaction

The present invention provides ruthenium compounds of the formula The compounds of the invention occur in the form of two isomers: trans and cis. The method of production of the compounds according to the invention is based on reacting an intermediate of formula (5) with a carbene complex of ruthenium. The invention also relates to the use of the compounds according to the invention for carrying out metathesis reactions.

Complex of ruthenium, method of production thereof and use thereof as (pre)catalysts of the metathesis reaction

The present invention relates to novel transition metal complexes of the formula (I) to a process for preparing these transition metal complexes and to the use of the transition metal complexes as catalysts in metathesis reactions.

Sulphur-containing metathesis catalysts

The invention relates to new (pre)catalysts of ruthenium complexes of formula 1,wherein L, X, X', R, R, Rand n are defined herein. The novel ruthenium complexes of formula 1 are convenient (pre)catalysts for metathesis reactions and can be applied, e.g., for ring-closing metathesis, cross metathesis or ene-ine metathesis reactions. Another aspect of the invention are the novel intermediates of formula 2.
