Reductive elimination of Et-Et (butane) from NiEt₂(bpy) (1) is enhanced by interaction with electron-accepting aromatic compounds, and the rate of the reaction (R) obeys the second-order rate law, R = k[1][aromatic compound]. A plot of k against Hammett's σ value gives a linear line with a ρ value of 1.4. ¹H NMR data support the coordination of C₆F₅CF₃ with 1, and reaction of C₆F₆ with 1 gives the first example of cis-type biarylnickel(II) complex Ni(C₆F₅)₂(bpy).
