Olefinic feedstocks may be oligomerized to form desired oligomers containing a preferred configuration which, in the instant case, is a linear product, by utilizing certain catalytic compositions of matter. The particular catalyst composite which will form a higher percentage of linear products comprises a porous support having composited thereon a catalytically effective amount of an iron group metal and a metal of Group IVA of the Periodic Table along with an alkyl aluminum halide and mercaptan. In addition, if so desired, the catalyst composite will also contain in combination therewith an aluminum alkoxy compound and an aluminum halide.
