Formation of the [(s-trans-η4-Butadiene)TaCp*Cp]+ Cation and Its Reaction with Organic Carbonyl Derivatives
Abstract: (Butadiene)TaCp*Cl2 (6) was treated with CpNa to yield (η2‐butadiene)TaCp*CpCl (7). Subsequent reaction with [Cp2ZrCH3+][CH3B(C6F5)3−] resulted in transfer of the chloride ligand from tantalum to zirconium with formation of the [(s‐trans‐η4‐butadiene)TaCp*Cp]+ cation [8, with CH3B(C6F5)3− anion]. Complex 8 was characterized spectroscopically and by an X‐ray crystal structure analysis. The group‐5 [(s‐trans‐η4‐C4H6)TaCp*Cp]+ bent metallocene cation complex 8 reacts with ketones (acetone, adamantanone) to yield …
