Catalytic dimerization of alkenes by nickel complexes in organochloroaluminate molten salts

Abstract

Organochloroaluminate molten salts based on aluminium trichloride or ethylaluminium dichloride and 1-methyl-3-butylimidazolium chloride, 1-butylpyridinium chloride or tetrabutylphosphonium chloride can be used as solvents for the catalytic dimerization of propene to hexenes isomers by nickel complexes.
