To a solution of bis (n-butylcyclopentadienyl)zirconium dichloride (1.001 g, 2.477 mmol ) and benzoic acid (0.900 g, 7.371 mmol ) in toluene (40 ml) at 25° C. was added triethylamine (0.871 g, 8.610 mmol ) with stirring. A white precipitate formed immediately which was removed by filtration. The title compound was isolated as a dark yellow oil in 84% yield by evaporating the solvent under vacuum. The title compound such prepared exhibit purity above 95% based on NMR results. 1H NMR (toluene-d8) δ 8.08 (s,6H), 7.01 (m,9H), 6.47 (m,2H), 6.22 (m, 2H), 2.80(t,J=7.6 Hz, 2H), 1.54 (m, 2H), 1.26 (m, 2H), 0.84 (t, J=7.2 Hz 3H).
