Abstract

Process for telomerizing noncyclic olefins having at least two conjugated double bonds with at least one nucleophile using a catalyst containing a metal of group 8, 9 or 10 of the Periodic Table of the Elements, wherein the overall telomerization process has a process step of catalyst recycling, in which hydrogen is added via a hydrogen source to the mixture present in this process step.
