ABSTRACT:
The invention concerns a procedure for manufacturing short-chain linear .alpha.-olefines, in particular 1-butylene, selectively from ethylene. 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, with or without a promoter, is used for a catalyst.
