Synthesis of cyclopentadienyl-, indenyl-, and fluorenylbis(pentafluorophenyl)boranes as ligands in titanium and zirconium half-sand wich complexes. The crystal structures of C₁₃H₉B(C₆F₅) ₂·t-BuNH₂, C₁₃H₈SiMe₃B(C₆F₅) ₂, and {η⁵-C₅H

10.1021/om970433j

The research focuses on the synthesis and study of various borane compounds and their complexes with titanium and zirconium. Key chemicals involved include bis(pentafluorophenyl)boron fluoride (C6F5)2BF?OEt2, which is used as a precursor to synthesize fluorenylborane (Flu)B(C6F5)2 and indenylboranes 1- and 2-IndB(C6F5)2. These boranes are further reacted with various metal compounds such as Zr(NMe2)4 and TiCl4 to form half-sandwich complexes like {C5H4B(C6F5)2}TiCl3. The study also explores the formation of adducts with tert-butylamine and investigates the catalytic activity of these complexes in ethene polymerization. The crystal structures of several compounds, including (Flu)B(C6F5)2?NH2CMe3, Flu(SiMe3)B(C6F5)2, and {C5H4B(C6F5)2}TiCl3, are determined by X-ray diffraction, providing insights into their molecular structures and bonding characteristics.
