A process for preparing 1-octene starting from butadiene is described, in which step (a) is carried out in the presence of a palladium based catalyst containing at least one trisubstituted monodentate phosphine in an aprotic polar solvent. Bis-hydrodimerization to 1,7-octadiene occurs, in the second step (b) 1,7 in the presence of a titanium compound activated with one or more Group 13 alkyl metals (chosen from boron, aluminum, allium, indium) Partial catalytic hydrogenation of octadiene to 1-octene occurs. |
