摘要 |
Process for the selective oligomerization of ethylene to give alpha-olefins essentially consisting of C4 to C8, character in that it is carried out in the presence of a catalytic system comprising the complex having general formula (II): (L)M(Y)n wherein L represents the ligand having general formula (I) M represents a transition metal; Y is selected from groups of an anionic nature bound to the metal as anion in ionic couple or with a covalent bond of the "sigma" type.
