Abstract
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.degree. C. in the presence of a catalyst consisting essentially of a 1,3-bis(diphenylphosphino)propane ligand of Co(II)(acetylacetonate).sub.2 or Co(III)(acetylacetonate).sub.3 or CoCl.sub.2 in combination with a dialkylaluminum halide such as diethylaluminum chloride.
