with a catalytic amount of B(C6F5)3 (2 mol %) at room temperature resulted in efficient σ-ligand coupling with the formation of the isomeric five-membered zirconacycloallenoid complex 9a. Two similar examples with different substituents R1 (SiMe3, tBu) were also investigated. All three new zirconacycloallenoids (9a–c) were characterized by X-ray diffraction.
