Abstract:
The invention concerns a catalytic composition comprising: at least one nickel precursor with an oxidation number of (+II) containing a phosphine ligand complexed with nickel, at least one Lewis base, and at least one activating agent selected from the group formed by chlorinated and brominated hydrocarbylaluminium compounds, used alone or as a mixture, in a manner such that the molar ratio of the ensemble of the Lewis base and phosphine ligand complexed with the nickel of the composition to the nickel is in the range 5 to 30. The invention also concerns the use of said catalytic composition.

Claim (Index 6):
The composition according to  claim 1 , in which the Lewis base is selected from diethyl ether, methyl tert-butyl ether, tetrahydrofuran, 1,4-dioxane, isoxazole, pyridine, pyrazine, pyrimidine, and phosphines with formula PR\u2032 1 R\u2032 2 R\u2032 3  in which the groups R\u2032 1 , R\u2032 2  and R\u2032 3 , which are identical, and which may or may not be bonded together, are selected from aromatic groups which may or may not be substituted and which may or may not contain heteroelements and/or from aromatic groups which may or may not be substituted and which may or may not contain heteroelements.
