A process for manufacturing short-chain linear α-olefines, in particular 1-butylene, selectively from ethylene by contacting ethylene with a catalyst employs, as catalyst, a nickel chelate in which the ligand is diphenyl(2-carboxymethyl)phosphine, diphenyl(2-carboxyethyl)-phosphine or an alkali metal salt of these, or an alkali metal salt of diphenyl(2-hydroxyethyl)phosphine.
