Abstract
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—N(R3)—P(R2)(R′2) or an iminobisphosphine ligand B2 of formula (R3)N═P(R1)(R′1)—P(R2)(R′2) or an iminobisphosphine ligand B′2 of formula (R3)N═P(R2)(R′2)—P(R1)(R′1). The invention also describes the use of said catalytic composition in a method for the oligomerisation of olefins.
