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 (R)(R')P—N(R)—P(R)(R′), or an iminobisphosphine ligand B2 of formula (R)N═P(R)(R′)—P(R)(R′). The invention also concerns the use of said complex in a method for oligomerisation of olefins.
