Abstract
The invention describes a novel dissymmetric nickel-based complex and the method of preparation thereof from at least one diphosphinamine ligand B1 of formula (R1)(R′1)P—N(R3)—P(R2)(R′2), or an iminobisphosphine ligand B2 of formula (R3)N═P(R1)(R′1)—P(R2)(R′2). The invention also concerns the use of said complex in a method for oligomerisation of olefins.
