Synthesis and characterization of tert-butylcyclopentadienyl derivatives of hafnium

Reaction of Si(C5H3-1,3-tBu2)Me3 with HfCl4 in toluene or hexane at room temperature afforded the new trichloro monocyclopentadienyl derivatives [Hf(η5-C5H3-1,3-tBu2)Cl3] (1). Treatment of [Hf(η5-C5H3-1,3-tBu2)Cl3] with the appropriate alkylating reagent in hexane gave the mono[1,3-di(tert-butyl)cyc...
