Pure 1,4-dienes are produced at high rates of reaction by reacting a conjugated diene and an alpha monoolefin at a temperature below 70° C. in the presence of a catalyst consisting essentially of a 1,3-bis(diphenylphosphino)propane ligand of Co(II)(acetylacetonate) 2 or Co(III)(acetylacetonate) 3 or CoCl 2 in combination with a dialkylaluminum halide such as diethylaluminum chloride. |
