Participants

Reaction Steps

To a solution of bis(n-butylcyclopentadienyl)hafnium dichloride (0.500 g, 1.012 mmol ) and pivalic acid (0.330 g, 3.230 mmol ) in toluene (30 ml) at 50° C. was added triethylamine (0.363 g, 3.240 mmol ) with stirring. A white precipitate formed immediately which was removed by filtration. The title compound was isolated as a dark yellow oil in 66% 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 6.15 (m, 2H), 5.90 (m,2H), 2.67 (t,J=7.6 Hz, 2H), 1.54 (m, 2H), 1.31 (m, 2H), 1.13 (s, 27H), 0.88 (t, J=7.2 Hz, 3H).
