To a solution of bis(1,3-dimethylcyclopentadienyl)zirconium dichloride (1.390 g, 3.99 mmol) and pivalic acid (1.520 g, 14.9 mmol) in toluene at 25° C. was added neat triethylamine (1.815 g, 18.10 mmol) with stirring. A white precipitate formed immediately which was removed by filtration. The compound was isolated as a pale-yellow powder in 88% yield and exhibited purity above 99% based on NMR results. 1H NMR (toluene-d8): δ5.84 (m, 2H), 5.53 (m, 1H), 2.18 (s, 6H), 1.13 (s, 27H).
