Oxidative addition of an aryl-halide to Ni(COD)₂ in the presence of an equivalent of amino-bis-phosphinimine ligand affords complexes of the form [HN(CH₂CH₂NPPh₃)₂Ni-Ar][X] (Ar = C₆H₄F, C₆H₅, X = Cl, Br) while the analogous reactions with 2 equivalents of Ni yield the amido-bridged complexes N(CH₂CH₂NPPh₃)Ni₂Br₃ and N(1,2-C₆H₄NPPh₃)Ni₂Br₃.
