The present invention relates to a process for the production of olefins by means of metathesis comprising the following steps a. Providing an olefin reaction mixture containing at least one olefin, b. Addition of a ruthenium compound of the general formula [RuX 2 L 1 x L 2 y] z (I) wherein X = anionic ligand; L 1 = neutral π-bonding ligand; L 2 = 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, d. Reaction at temperatures in a range from 30 ° C to 140 ° C, with no addition of an alkyne or alkynol.n n n The invention further relates to the use of this method in metathesis reactions. |
