Abstract
A process for the telomerization of dienes with a telomerizing compound containing a mobile hydrogen atom is disclosed wherein the reaction between the diene and the telomerizing agent is effected in the presence of a catalytic system comprising a water-soluble sulfonated triaryl phosphine compound, preferably a water-soluble salt of a mono-, di-, or trisulfonated triphenyl phosphine and a transition metal compound, preferably palladium or a palladium-containing compound. Water is added either before or after the reaction is completed and the reaction products can easily be separated from the aqueous catalyst solution.
