Abstract
The invention relates to a method for producing compositions containing unsaturated compounds, wherein (A) one or more unsaturated monocarboxylic acids having 10 to 24 C-atoms or esters of said monocarboxylic acids and optionally (B) one or more compounds having at least one C═C double bond (wherein the compounds (B) are different from the compounds (A)) are subjected to a tandem isomerization/metathesis reaction sequence in the presence of a palladium catalyst and a ruthenium catalyst, providing that the palladium catalysts used are compounds that contain at least one structural element Pd—P(RRR), wherein the radicals Rto R, independently of one another, each comprise 2 to 10 C-atoms, which may be aliphatic, alicyclic, aromatic or heterocyclic respectively, providing that at least one of the radicals Rto Rcontains a beta-hydrogen, wherein the palladium catalyst is used as such or is produced in situ, providing that the method is carried out in the absence of substances that have a pKa value of 3 or less.
