The invention relates to a catalytic composition comprising: at least one nickel precursor with a degree of oxidation (+II) and containing a phosphine ligand complexed with nickel, at least one Lewisbase, and at least one activating compound selected from the group containing the chlorinated or brominated compounds of hydrocarbylaluminium, either alone or in admixture, such that the molar ratio of the Lewis base and nickel-complexed phosphine ligand of the composition to the nickel is between 5 and 30. The invention also relates to the use of said catalytic composition. 本发明涉及催化组合物，其包含：至少种氧化数为(+II)的镍前体、至少种路易斯碱以及至少种选自氯化烃基铝化合物和溴化烃基铝化合物的活化剂(其单独地或作为混合物使用)，所述镍前体含有与镍配合的膦配体，其中所述组合物的路易斯碱和与镍配合的膦配体的总体与镍的摩尔比为5-30。本发明还涉及所述催化组合物的用途。
