To a suspension of 2.46 g (7 mmol) of cyclopentadienyl zirconium trichloride in toluene, a suspension of 1.6 g (7 mmol) of potassium (3-trimethylsiloxypropyl)-cyclopentadienide in toluene is added. A yellow-brown-coloured suspension immediately precipitates. The reaction is maintained for 12 hours. Subsequently, the solution is filtered and concentrated and a crystalline white solid is formed (0.8 g, 2 mmol, 28%). 1H-NMR (C6D6): 5.87 (t, 2H), 5.65 (t, 2H), 3.46 (m, 2H), 2.74 (m, 2H), 1.73 (m, 2H), 0.14 (s, 9H). 13C-NMR (C6D6): 11.6.9, 115.0, 114.7, 112.2, 61.8, 33.6, 26.8, −0.393. Mass spectrum: M+-65(356): 30%.
