20100174068 | Complex of Ruthenium and Osmium, Method of Production Thereof and Use Thereof As (Pre)Catalysts of the Metathesis Reaction - Complexes of ruthenium and osmium according to the invention are represented by formula (1), in which M denotes ruthenium or osmium, L denotes a neutral ligand selected from the group comprising amines, imines, phosphines (preferably stilbines, arsines, alcohols, thiols, ethers and thioethers or an N-heterocyclic carbene (NHC) ligand). The compounds of formula (1) occur in the form of two isomers: trans and cis. The method of production of complexes of ruthenium and osmium of formula (1) according to the invention is based on reacting an intermediate of formula (5) with a carbene complex of ruthenium or osmium. The invention also relates to the use of the complexes according to the invention for carrying out metathesis reactions. | 07-08-2010 |

20080319199 | Preparation of Catalysts - The present invention discloses a novel synthesis method for a catalyst of formula 6, wherein Mes has the meaning of mesityl. | 12-25-2008 |
20130079575 | METHOD OF PRODUCING OLEFINS VIA METATHESIS - 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. | 03-28-2013 |
