An improved process for the preparation of higher aluminum alkyls by a chain growth reaction of an .alpha.-olefin and especially ethylene with a lower molecular weight aluminum alkyl or aluminum hydride uses a catalyst system which comprises at least one of (a) a metallocene of a transition metal and an aluminoxane (b) a cationic transition metal metallocene complex with an inert, non-coordinating anion, and (c) a cationic transition metal metallocene complex with an inert, non-coordinating anion and a hydrocarbylaluminoxane. Higher purity alpha olefins can be recovered by olefin displacement. Alternatively, linear primary alcohols can be produced by oxidation and hydrolysis.
