The invention describes a novel catalytic composition comprising at least one nickel precursor A with at least one diphosphinamine ligand B1 of formula (R1)(R'1)P&#x2014;N(R3)&#x2014;P(R2)(R&#x2032;2) or an iminobisphosphine ligand B2 of formula (R3)N&#x2550;P(R1)(R&#x2032;1)&#x2014;P(R2)(R&#x2032;2) or an iminobisphosphine ligand B&#x2032;2 of formula (R3)N&#x2550;P(R2)(R&#x2032;2)&#x2014;P(R1)(R&#x2032;1). The invention also describes the use of said catalytic composition in a method for the oligomerisation of olefins.

Nickel-based catalytic composition and use thereof in a method for the oligomerisation of olefins

The invention describes a novel dissymmetric nickel-based complex and the method of preparation thereof from at least one diphosphinamine ligand B1 of formula (R)(R')P&#x2014;N(R)&#x2014;P(R)(R&#x2032;), or an iminobisphosphine ligand B2 of formula (R)N&#x2550;P(R)(R&#x2032;)&#x2014;P(R)(R&#x2032;). The invention also concerns the use of said complex in a method for oligomerisation of olefins.
