The invention relates to a process for the telomerization of acyclic olefins having at least two conjugated double bonds (I) or mixtures in which such olefins are present with nucleophiles (II) using a metal-carbene complex as catalyst.

Method for the telomerisation of non-cyclic olefins

The invention relates to a process 1-olefins by telomerization of compounds having conjugated double bonds with a telogen in the presence of a noble metal telomerization catalyst, hydrogenation of the telomer and cleavage of the hydrogenated intermediate. Use of the 1-olefin as comonomer.

Method for producing 1-olefins using palladium carbene compounds

The invention relates to a process for preparing 1-octene by telomerization of 1,3-butadiene using a reducing agent in the presence of a telomerization catalyst and partial hydrogenation of the octadiene obtained in this way.

Method for the production of 1-octene by reductive telomerisation
