| abstract |
The present invention relates to a method for producing olefins by means of metathesis, comprising the following steps: a. provision of an olefin reaction mixture containing at least one olefin, b. addition of a ruthenium compound of the general formula [RuX2L1 xL2y]z (I), wherein X = anionic ligand; L1 = neutral π-bonding ligand; L2 = neutral electron donor ligand; x = 0, 1; y = 1, 2, 3; z = 1, 2, c. addition of a Lewis acid and/or an anionic non-coordinating salt, and d. reaction at temperatures in the range from 30°C to 140°C, wherein no alkyne or alkynol is added. The invention further relates to the use of said method in metathesis reactions. |
