Abstract: The present invention relates to a method for producing compositions containing unsaturated compounds, wherein (A) one or a plurality of unsaturated monocarboxylic acids with 10 to 24 C atoms or esters of these monocarboxylic acids and (B) one or a plurality of unsaturated dicarboxylic acids with 4 to 20 C atoms or esters thereof are subjected to a tandem isomerization/metathesis reaction in the presence of a palladium catalyst and a ruthenium catalyst, with the condition that compounds which contain at least one Pd-P(R

2 R
3 ) structure element are used as the palladium catalysts, wherein the R
1 to R
3 radicals each - independently of one another - have 2 to 10 C atoms, which can each be aliphatic, alicyclic, aromatic, or heterocyclic, with the condition that at least one of the R
1 to R
3 radicals contains a beta hydrogen, wherein the palladium catalyst is used as such or generated in situ, with the condition that the method is performed in the absence of substances having a pKa value of 3 or less.
