To a solution of bis(n-butylcyclopentadienyl)zirconium dichloride (1.001 g, 2.477 mmol ) and pivalic acid (0.760 g, 7.451 mmol ) in toluene (25 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 light orange oil in 78% yield by evaporating the solvent under vacuum. The title compound such prepared exhibit purity above 95% based on MNR results. 1H NMR (toluene-d8) δ 6.22 (m,2H), 5.97 (m,2H), 2.61 (t,J=7.7 Hz, 2H), 1.51 (m, 2H), 1.29 (m, 2H), 1.11 (s, 27H), 0.87 (t, J=7.2 Hz 3H).
